JUPITER 2022 SEASON

By Christopher Go

All images were taken using a Celestron C14 mounted on an Astrophysics AP900GTO mount. A QHY 290M, QHY5III200M and a QHY5III462C cameras were used is these images. RGB is done using a set of Chroma Technology RGB filters on a Starlight Xpress Motorized filter wheel. Methane band images are done using a Chroma Methane Band filter (889nm 18nm bandpass). UV images are done using a Astrodon UV filter. Amplification is done using an Astrophysics Advance Convertible Barlow working at 2.0X.

Image acquisition was done using Torsten Edelmann's Firecapture 2.5/2.6 64bit software. All images are NORTH UP! Processing was done using AutoStakkert! and Registax.

These images were taken at Banilad, Cebu City, Philippines.

January 15, 2023

This is my first image of the year. Monsoon had been horrible. Imaging Jupiter has become very challenging. It is getting lower in the sky and closer to my hot roof. Seeing was very unstable.

The GRS is rising on the left. The chimney above the GRS seems open. Io shadow is to the left. I used the new Winjupos feature of moon derotation and it works perfectly! The NEB is quiet in this region.

December 29, 2022

We had horrible monsoon during the last week. The sky finally cleared today. Seeing was unstable during the start of my imaging (a few minutes after sunset) run but improved as the sky got darker.

These images show the region just before the GRS. Note the huge dark cyclonic oval on the NEB. There are two bright outbreaks on the NEB but these are not bright in methane band. The SEBn shows the turbulence from the GRS. The GRS can be seen rising on the last image.

December 23, 2022

After imaging the Iapetus Transit on Saturn, I turned to Jupiter. I wanted to image before the thunderstorm would arrive. Seeing was mostly good but transparency was poor. I also had problems with powerful gusts which really degraded the image.

The NEB shows some active rifts on the later images. The cyclone on the NEBn are huge! The SEB is quiet in this region. Io's shadow can be seen on the right edge of the SEB. Note the complex wake on the STB preceding a dark cyclonic oval.

December 22, 2022

Condition was terrible today. I was only able to capture a set of RGB at very poor transparency.

The GRS is prominent on this image. The chimney above the GRS is open. The EZ looks interesting with some bright clouds close to the CM. The NEB is still very narrow. Callisto can be seen above Jupiter.

December 18, 2022

I had a quick run today with Jupiter. Quick because a heavy thunderstorm was headed our way! I was only able to do 3 sets of RGB before the clouds arrived and I had to runs shutting things down. A few minutes after the had everything covered, it rained very hard with gust of up to 50kph! I am very worried with my mount and OTA now. It is still raining hard at this moment with gust shaking our house!

The GRS is setting on this image. The wake of the GRS is very turbulent. The NEB is still very narrow as it slowly recovers.

December 16, 2022

The QHY5III462M finally arrived yesterday. Unfortunately we had a heavy thunderstorm all night! Today, it was cloudy all day and we had a thunderstorm late afternoon to early evening. I wasn't expecting to image but the sky cleared. Seeing was unstable.

I was able to test the QHYIII462M vs the QHYIII200M. The first two RGB images were captured using the 462M while the third on was with the 200M. The IR image was captured using the 462M and an IR 850nm pass filter. The earlier methane band image was taken using the 462M and the later one with the 200M.

The noise level of the 462M is very similar to the 290M. But the 462M is more sensitive in visible light to NIR compared to the 290M. The 200M was more sensitive in visible light than the 462M plus with lower noise. The 462M is more sensitive in methane band than the 200M but the low noise of the 200M compensates this. I will do another test tomorrow if conditions will be better.

These images show the area captured by Juno during PJ47. Oval BA is prominent and the faint orange ring can be seen. The SEB is calm in this region. There is a bright outbreak on the NEB but this outbreak is not bright in methane band.

December 14, 2022

Condition was very bad today. Seeing was unstable and transparency was very low.

This is the region before the GRS. The STB is very turbulent here. There is a huge cyclonic oval in the NEB.

December 13, 2022

Weather had been horrible here for the last 10 days. We finally had some clearing. Unfortunately transparency was poor due to thin clouds and seeing was variable but with some periods of good seeing. I was even able to capture a decent UV image.

The GRS is past the CM. The GRS halo has really pushed north. The wake of the GRS is turbulent with a very prominent outbreak. The barge SW of the GRS is very dark especially in methane band. The NEB is very narrow with a lot of rift activity.

December 3, 2022

Weather had been very bad during the last few days. Today I had to image though clouds. Transparency was very poor. I used the QHY5III462C for these images.

The GRS looks very oblate. The chimney above the GRS is open. The wake of the GRS is very active. The SEB above the GRS is pale! The NEB shows a huge cyclonic spot.

November 28, 2022

The sky was hazy today and seeing was variable.

The GRS is well resolved in these images. The dark core can be clearly seen. The chimney above teh GRS is open. It is interesting to note that some parts of the SEB are very pale. In the NEB, There is a large cyclonic oval.

November 27, 2022

Seeing was very variable today.

Oval BA can be seen rising on the left. The STB is dominated by a large cyclonic oval with a very dark wake. The NEB shows some complex rifts. The NEB cyclonic ovals are getting very big.

November 26, 2022

Condition was excellent today.

The GRS is well resolved. Note the outbreaks on the wake of the GRS. Note the very dark spot on the wake of the GRS. Some parts of the wake of the GRS is bright in UV. The chimney above the GRS seems to be opening again. There are some activity in the NEB. The bright spot is prominent but it is not very bright in methane band.

November 25, 2022

The sky was clear today but seeing was unstable.

Oval BA is well resolved in these images. The light orange ring is can be seen. The NEB is very active. Note the huge cyclonic oval on the NEBn.

November 24, 2022

It was mostly cloudy today. I had to take these image between clouds before the sky became totally overcast.

The STB is very active in this region. The dark wake feature seem to be interacting with the white oval on the left. The SEB is red here. The NEB is still narrow. The large oval cyclone on the NEB seems to be getting bigger.

November 22, 2022

Condition was good today but deteriorated during the last minutes of this imaging run. I was able to capture some UV images but the quality is not very good. The methane band images however is stunning.

Note the bright outbreak on the NEBs. This feature is bright in methane band. The STB is very active in this region. Note the dark wake. The end of this wake is a white cyclonic spot to its left. This spot is pitch black in methane band but very bright in UV.

November 21, 2022

I had a frustrating imaging run today. Seeing was good but clouds rolled it. I had to image the methane band through sucker clouds. It was overcast after the methane band image! I used the QHY5III462C to capture this images. It is just easier to process planetary images during satellite transits using a color camera.

The GRS is well resolved. Note the bright streak close to the core of the GRS. The hook around the GRS has faded. There seems to be some flaking on the SW side. In methane band, the GRS looks distorted. The chimney above the GRS is close. There is a bright outbreak on the wake of the GRS. Io can be seen on the SEB.

The NEB looks quiet in this region. Note the large white clonic oval on the NEB above the GRS. This feature is suppose to be cyclonic but it is bright in methane band!

November 15, 2022

These images were taken using the QHY5III200M. Seeing was excellent this evening.

Oval BA is well resolved. Note the light orange ring inside Oval BA. There are a lot of details resolved even up to the poles.

November 14, 2022

This is my final test run with the QHY5III200M. This camera has proven to be the best monochrome camera available. It's sensitivity even in NIR and it's very low noise makes this an incredible camera. From now on this will be my new default camera. Seeing was excellent today and the sky was totally clear.

The GRS is prominent in these images. Note a white streak inside the GRS on the upper right of the dark core. Io shadow can be seen over the wake of the GRS. There are a few outbreaks on the wake which is visible in methane band. The NEB is quiet in this region.

November 12, 2022

I had clear skies today. Seeing was good. I have retired my QHY290M in favor of the QHY5III200M. This camera is far superior in noise and it's NIR is even better than the QHY5III462C!

The NEB is still reviving with mostly the southern half of the NEB being dark red. Note the huge dark cyclonic oval on the NEB. The SEB looks very turbulent.

November 11, 2022

I had two imaging runs today. The first run was cut short by clouds. I am also testing a new monochrome camera. This is the QHY5III200M. I have to say this is the best monochrome camera available now with an incredible IR sensitivity. I will write a full review of this camera. Seeing was good but transparency was variable.

These images show two different regions of Jupiter. The first run shows Oval BA setting on the right. My second run shows the GRS. Note the GRS is very distorted and looks very squarish probably. There is a small white oval on the upper left side of the GRS which is probably the reason of the distorted shape of the GRS. The hook that was surrounding the GRS seems to be breaking up.

November 8, 2022

There was a total lunar eclipse today. The crazy thing was that the moon was covered with clouds but Jupiter was clear. I had my C8 pointed at the moon and my C14 was imaging Jupiter. Seeing was average but transparency was variable.

Oval BA can be seen in these images. Note the orange ring inside Oval BA. There is a complex white streak on the SEB. The NEBs/EZn is very active with the dark blue festoons interacting with the NEB. The methane band image shows a complex north polar hood which is pushing south!

November 7, 2022

Condition was a bit unstable today. I imaged early to be able to capture the GRS.

The GRS is setting on the right. Note the wake of the GRS pushing to the north over the GRS. The NEB is quiet in this region.

November 5, 2022

Condition was perfect this evening!

The details on these images are incredible. Many fine details form pole to pole. The STB shows a very complex wake on the p side of a cyclonic white oval. The SEB looks dark now and probably has revived. The NEB shows a huge cyclonic oval on the CM. The IR850 images shows some spots on the south pole!

November 4, 2022

The sky was cloudy early this evening but cleared up. This is my first real clear sky in weeks! Seeing and transparency were excellent.

The GRS is very well resolved in these images. Note the outbreak in the wake of the GRS. This feature is bright in methane band. The chimney above the GRS is close. Note the huge cyclone oval on the NEB above the GRS.

November 2, 2022

It was cloudy early evening but the sky cleared as the remnant of a tropical depression dissipated. Seeing and transparency was good.

There are disturbance like features on the SEB and the STB. These feature are bright in methane band. The NEB is quiet in this region.

October 31, 2022

It was cloudy early this evening. Fortunately the sky cleared up. Seeing was average but transparency was poor during the start of my session.

Oval BA is prominent in these images. It is still pale with a light orange ring inside. The STB has really revived after so many years of being white! Note the large cyclone preceding Oval BA. The SEB is very turbulent in this region and it seems to have a much red color. The NEB is thin in this region. Note an active region rising on the left.

October 30, 2022

I finally had some clearing after more than a week of bad weather due to a tropical storm. Seeing was average but transparency was very poor.

The GRS shows it's elliptical shape compared to the more recent circular shape. The chimney above the GRS is close. The NEB after the CM looks very chaotic. The methane band of this region looks very interesting. The EZ feeston seem to be interacting with the NEBs or even the NEB cyclone.

October 23, 2022

It was mostly cloudy today. I had to image Jupiter through clouds. Seeing and transparency was bad.

The GRS is well resolved. Note the "chimney" above the GRS looks like its opening again. There is a bright outbreak on the wake of the GRS. The NEB is wide in this area.

October 21, 2022

It was mostly cloudy early this evening. But the sky cleared. Seeing was excellent.

Note the disturbance like feature on the STB and the SEBn. The NEB is quiet in this region. Note the large red spot on the NNTZ.

October 20, 2022

I did not expect to image today as it was overcast. Before going to bed, I went out one last time and saw Jupiter. The sky was still totally cloudy but there was thin clouds around the GRS. Seeing was perfect but transparency was very poor.

The GRS is well resolved in this image. The chimney above the GRS is close now. There is an outbreak on the wake of the GRS. Io and it's shadow can be seen on the SEB.

October 15, 2022

Condition was terrible today due to a tropical storm on the northern tip to the Philippines.

I imaged two session. The first session shows Oval BA while the send session shows the GRS. The chimney above the GRS is open. The NEB is almost fully revived.

October 11, 2022

We had a powerful thunderstorm early this evening. Surprisingly the sky cleared up at around 8pm. However seeing and transparency wasn't very good.

The GRS is well resolved. The wake of the GRS is very complex and seem to be spilling into the STrZ! This is a bit weird. This may be due to an outbreak very close to the halo of the GRS. The chimney above the GRS seem to be closing. Note the very bright white cyclonic oval on the STB close to the CM.

Note the outbreaks of the NEBs. It seems it is these small and short term outbreaks that is slowly reviving the NEB. At the NPR, 2 white ovals can be seen. These are the polar ovals that Juno images during Perijove.

October 9, 2022

The sky was totally overcast this evening. I was about to give up. Before going to bed, the checked the sky one last time. There was a clearing around the moon and Jupiter. With Jupiter close the the zenith, seeing was perfect though transparency wasn't great because of some thin clouds.

The SEB/NEB revival seem to be ongoing. Note the long bright white patch on the SEBn just before the CM.

October 8, 2022

The sky was mostly cloudy this evening except of a round patch around Jupiter. I was have second thoughts about imaging because there was a coming thunderstorm. I went ahead an image anyway. I only had a short run before the sky became complete overcast. Seeing was average but transparency was very poor.

The GRS is rising on the left and Oval BA is setting on the right. The NEBs has become very dark. The STB at the CM and to the left of the small white oval shows a region with what seems to be small reddish ovals embedded in a dark band.

October 7, 2022

The sky was totally overcast this evening. There was some clearing around the area of Jupiter. I was a bit nervous because there was a thunderstorm around us. I was able to get enough data sets before the sky became overcast again.

The methane bright north polar hood extention Andy Casely and I observed last week is gone! It seems that was just a temporary feature. The NEB revival is at full swing. The SEB also seems to be reviving.

October 6, 2022

The sky was mostly cloudy today. I had a short clearing around Jupiter so I took the chance. Seeing wasn't great and transparency was poor!

The GRS is prominent on these images. Note the flake on the p side which is prominent in the methane band image. The chimney above the GRS is open. Io and it's shadow can be seen on the right edge of the SEB. The dark NEB barge above the GRS has become totally white. The NEB's color is growing and spreading north.

October 4, 2022

Conditions were perfect today. Seeing was 10/10!

The NEB looks very active in this region. The NEB revival is underway but slowly with outbreaks associated with the EZ festoons. The SEB still looks pale. In the methane band, the north polar hood has really spread south in this image. This has been confirmed in the latest Juno Spacecraft image.

October 3, 2022

I didn't expect to image today because it was very cloudy and the satellite image wasn't promising. But I did have a clearing around the area around Jupiter.

There is a bright outbreak on the NEB. Lately short period outbreaks have appeared in this area so we will see how long this one will last. Oval BA can be seen on the right. It is still very pale. The GRS is rising on the left on the last images. The south polar red spot can also be seen.

October 2, 2022

I imaged Jupiter early today when it was still low in the sky. Seeing was variable and transparency was poor.

These images show the NNTZ LRS very well. The NEBs shows what seems to be multiple outbreaks but these aren't prominent methane band. The north polar hood seems to be spreading south in the methane band.

October 1, 2022

Finally had a decent night. Seeing was very good.

The GRS is prominent in these images. Details in the core are resolved. The "chimney" above is open! There are active outbreak on the wake of the GRS. The NEBs is very dark. Revival seems very slow. Note the large grey cyclonic oval at the CM.

September 30, 2022

Here is my image of Jupiter today. Just a single set of RGB (30s/channel and no derotation) because that was the only time I had before clouds rolled it. Seeing was only 8/10.. We are having a terrible monsoon right now.

This image shows Oval BA still very pale. Note the bright clouds on the SEBn spreading to the EZs. It would be interesting to see this in methane band. The NEB shows the anticyclones on the NEBn alternating with the cyclonic ovals below them.

September 28, 2022

Came back from my trip to Starmus in Armenia and Europe. Condition here since I arrive had been terrible. I was lucky to have a brief clearing before the clouds rolled in. Seeing was good but transparency was very poor.

The GRS is rising on the left while Oval BA is setting on the right. The STrZ between the GRS and Oval BA is very turbulent. Note the dark reddish feature on the STrZ before the CM. The South Polar red spot can be seen in these images. The NEBs is getting darker. Note the dark red barge on the NEB.

August 28, 2022

The sky was clear again. Seeing was almost perfect except for some turbulence during the start of my imaging run. My next images will be 3 weeks from now. I'm flying to Armenia today to give a workshop at the Starmus Festival.

There is a bright outbreak like feature on the NEBs. Surprisingly, while it is bright in methane band, it is not blazing bright. The NEB looks chaotic in this region.

The GRS show flaking on the p side. The chimney above the GRS seems to be opening up. The south polar red spot can be seen in these images. Volcanic Io is transiting over the SEB.

August 27, 2022

I finally had a decent imaging run. Seeing was very good with clear skies. I took these images while Jupiter was still low in the sky!

It was at first impressed with the very bright outbreak on the NEB. This feature isn't as impressive in methane band. The NEBs is very dark. The SEB looks very turbulent.

August 23, 2022

I had a frustrating run today. I woke up around midnight and the sky was clear to setup. As I completed my setup, it was overcast. A few minutes later it rained hard! I tried again 1 hour later. There was a clearing around Jupiter. As I started to image, clouds started to roll in. Seeing was perfect but I had to image through clouds. Unfortunately, I only had enough data for one image.

The GRS is well resolved in these images. Note the two bright outbreaks on the wake of the GRS very close to the halo of the GRS.

Note the interesting feature on the NEB on the right edge. This feature looks like a big outbreak.

August 19, 2022

The monsoon here had been horrible. Heavy rain and flooding almost everyday! I had a lucky break today. Unfortunately transparency was very poor as I had to image through clouds! That is why I have a lot of artifacts on my CH4 image due to using crazy high gains! Seeing was surprisingly excellent!

The STrZ is very active in this region with a lot of dark spots lining up. The SEB is pale in this region. The NEB is quiet in this region but the reddish belt seems to be expanding.

August 13, 2022

I had a miracle night tonight. The sky was mostly cloudy with thunderclouds in the north and south. I could even hear the thunder around me. But the area around Jupiter remained clear. The seeing was very variable but mostly good. I got to image Jupiter in UV for the first time in years. I used a Astrodon UVenus filter for this.

The area around the GRS is very active and turbulent! The STrZ preceding the GRS is very chaotic! There is a flake of the f side of the GRS. The wake of the GRS is also very active with many outbreak activity. The two white spots below the GRS is bright both in UV and methane band.

Note the bright outbreak on the NEBs on the left. This outbreak is bright in methane band. This looks like the usual outbreak around the festoons.

August 11, 2022

After imaging Saturn, I went straight to image Jupiter even though it was still low in the sky. Seeing was terrible.

The GRS is prominent in this image. It really squished on the left side compared to last month. There is a faint flake on the f side. In the methane band, note the bright extension to the SE. Note the two small ovals lining up to the south of the GRS.

The NEB looks like it is expanding to the north. Note some bright features in the methane band embedded in the festoons on the right.

August 2, 2022

The sky was clear this morning which was a surprise because the cloud condition from the satellite images did not look good. Seeing was perfect today. The resolution of the images is incredible. Features can been seen in the poles.

Note the CH4 bright spot in the SEB close to the CM. This feature is not very clear in the color image but will this spot develop into something interesting? Is this an anticylonic oval or an outbreak? Overall, the SEB looks very turbulent. The STB looks is very complex in this region. The NEB's dark band is expanding. It seems that the revival is on it's way but there is not bright outbreak visible in this region.

August 1, 2022

Two tropical systems have enhanced the monsoon here. I was fortunate to have a brief clearing before things deteriorated. Seeing started good but became bad as clouds rolled in.

The GRS is rising on the left while Oval BA is on the right. The region between these two spots is very complex. As Shinji has commented, the chimney above the GRS has closed.

Note the huge cyclonic feature on the NEB at the CM. This feature is almost as big as the GRS! Seems like the two anticyclonic ovals are squeezing it.

July 26, 2022

Another perfect day! Seeing and transparency was just amazing.

Oval BA can be seen rising on the left. The SEB is very turbulent in this region. The dark red part of the NEB is wider in this region. It really looks like the NEB is reviving despite the lack of prominent outbreaks. There is an interesting red spot on the NTrZ.

July 22, 2022

Condition was perfect this morning!

The GRS is well resolved in these images! Details can be seen inside the GRS. The chimney above the GRS is open. The SE side of the GRS is very chaotic. There is a very bright outbreak on the wake of the GRS! The NEB is quiet in this region.

July 21, 2022

The monsoon season is really very bad this year. Fortunately, Jupiter is so high up now (80deg) that image quality has been incredible! Seeing was great. For the color images, the first image was done with the QHY290M while the second image was using a QHY462C OSC camera.

The NEB is active in this region with some bright outbreaks. Interestingly, these outbreaks are not very bright in methane band but seems to be the result of the activity on the festoons. There is an interesting feature on the SEBn after the CM. Note the bright oval that is interacting with the EZ.

July 15, 2022

When I woke up, the ground was completely wet. Fortunately the sky was mostly clear. Seeing was horrible during the start but improved just before sunrise.

Here is an interesting image of the GRS partly covered with Europa's shadow. The chimney above the GRS is open. There is a bright outbreak on the wake of the GRS. This outbreak is bright in methane band. The NEB's dark band seem to be expanding.

July 12, 2022

The monsoon weather here has been terrible. This is the first time I have been able to image in more that a week. Seeing was good but transparency was very poor due to thin clouds.

The orange ring inside Oval BA is well resolved. It is interesting that Oval BA is slowly regaining color but not as red as in 2006. Note the reddish oval on the p side of Oval BA. This oval seems to be getting closer to Oval BA. Will this merge with Oval BA? The GRS can be seen rising on the left.

The SEBn looks very turbulent. The NEB looks quiet with interesting dark barges.

July 2, 2022

We had horrible weather here for a week due to two tropical systems. The sky cleared today and conditions were perfect with Jupiter over 70deg in altitude.

Incredible details all over Jupiter. Something seems to be brewing on the SEBn/EZs just past the CM. Note the large bright feature at the edge of the dark band that seems to be interacting with the EZ. There are some bright outbreaks on the NEBs/EZn which are bright in methane band.

June 26, 2022

I finally had some clearing have a miserable week of rain! Seeing was perfect and I was able to capture incredible details despite using an OSC camera.

Oval BA can been seen just before the CM. Note the small red oval preceding it. The GRS is rising on the left with Io just above it. The NEB looks really faded in this region. Note the dark red barge at the CM.

June 17, 2022

I had crazy conditions today. When I woke up, the sky was mostly clear. Set up my system, and when I was ready to image, the sky was overcast! I gave up but after taking down everything, the sky cleared again! Set up again, took some images before the sky really became overcast. Seeing was excellent today. Though transparency was poor.

Note the wavy pattern on the NEB due to the interaction of the white anticyclones and the alternating red cyclones. The EZ looks very turbulent. A lot of features can be see up to the poles.

June 16, 2022

I was having second thoughts about imaging today. 2/3 of the sky was covered with heavy thunderstorm clouds while the eastern sky around Jupiter was clear. I was scared because it might rain and the heavy cloud was overhead. Fortunately, it didn't rain and the seeing was fantastic! Although I had to image through some thin clouds.

The GRS is prominent in these images. The "chimney" above the GRS seems open. This feature is bright in methane band. The outbreaks on the wake of the GRS is active. Oval BA can be seen setting on the right. Note the strange cyclonic feature on the NEB just past the CM.

June 15, 2022

Seeing was excellent today. Subtle features can be seen!

The STB/STrZ is very chaotic in this region. The NEB and SEB are still the same. No sign of the revival outbreak. The reddish mid-EZ band is still prominent.

June 12, 2022

I finally had a clearing after days of clouds and rain. Seeing was initially unstable but improved as Jupiter got higher.

The STrZ looks busy in this region. The two dark spots at the CM seems to be interacting. The NEB and SEB looks the same as before. Ganymede can be seen on the lower left of the 2nd color image.

June 8, 2022

Condition was average today. There was a thin haze that affected transparency.

The SEB is pale in this region. The NEB shows a lot of cyclonic and anticyclonic spots but most of the NEB is still very pale. Note the two white spots on the N3TZ. One of squished to the brighter one. The bright spot is an anticyclone while the lighter one seems to be a cyclone.

June 6, 2022

Condition during the last weeks were horrible. It would be clear during the day but cloudy when it is time to image Jupiter. I was lucky to have a break in the clouds. Seeing was good but I still had to deal with some thin clouds.

Oval BA is at the CM. Note the prominent reddish ring. The GRS is rising on the left. Note the chimney above the GRS is open. Note the large yclonic feature on the NEB. The NEB anticyclonic spots are very bright in methane band.

May 27, 2022

I finally had some clearing this morning but only for a brief moment. Here is an image of Jupiter with Calllisto. Unfortunately, the sky became overcast as I was about to capture methane band. Seeing was only average and transparency was poor due to thin clouds which became overcast.

The SEB looks a little strange especially on the left edge. There seems to be a circulation from the EZ pushing into the SEBn which seems to cut the SEB almost in half. The NEB is quiet in this region.

May 23, 2022

It was mostly cloudy this morning but I had a brief clearing in the direction of Jupiter. Seeing and transparency was good.

The GRS is prominent in these images. The core of the GRS is well resolved. There is a bright outbreak in the wake of the GRS. The south polar red spot can be seen at the CM. The NEB is quiet in this region.

May 19, 2022

This year has to be the worst dry season ever! It has been cloudy and raining it was the wet season! I was fortunate to get a break in the clouds today. Although I only had sufficient time to capture RGB.

Note the dark spots lining up on the STrZ and the large STB dark oval. The SEB still looks very pale. The NEB n is still very pale.

Condition was unstable when I took the methane band image because Jupiter was still very low in the sky. It became excellent when Jupiter got higher.

The STB is very active in this region. Note the large dark oval on the STB on the right. The SEB is very turbulent on it's north and south side but the mid SEB is still plae. The NEB is still mostly pale except of it's southern edge. Note the bright circulation feature on the NEB just before the CM. Note the red spot on the NNTZ which is bright in methane band.

Europa and it's shadow is transiting Jupiter on these images.

Seeing was average today. Jupiter is still around 30 deg altitude when I took these images.

The GRS is prominent in these images. The halo is very dark. The wake of the GRS is chaotic. Oval BA is setting on the right. The wake of Oval BA is very dark. There is a strange feature on the NEB to the left of the CM and one below WSZ. These features are dark in methane band. Are these cyclonic ovals?

Finally some decent conditions. Jupiter was only around 35deg when I took these images. For the methane band I had to stay with the QHY290M because I was in the race against the rising sun.

The STrZ is quite busy with the dark spots lining up. The SEB is turbulent on it's northern and southern parts but the mid-SEB is still very pale. Note the dark feeston on the NEBs and the CM. This feature is also very dark in methane band. The NEBs is very dark and although there seems to be some bright "outbreak" spots, these are not bright in methane band. The rest of the NEB is still very pale. The distorted Io can be seen on the right.

Seeing was still unstable today due to Jupiter's altitude.

Ganymede can be seen on the STB. The SEB is very pale. Note the bright feature on the EZ/SEBs at the CM. Unfortunately I wasn't able to capture any methane band images due to sunrise. Most of the NEB is still very pale except for the southern border.

Imaging Jupiter is still very challenging because it is very low in the sky and I had to image very close to sunrise.

The GRS is prominent in this image. The wake of the GRS is active here. The northern edge of the GRS halo is very dark and it seems that the "chimney" above the GRS is about to open. Note the STB white spot at the edge on the right. It looks like this spot has become as big as Oval BA!!

The EZ looks very active. Note the SEB/EZ border. Something seems to be brewing there. The NEB seems to be reviving as the NEB is is very dark.

Poor conditions today. I was only able to capture a single RGB at poor transparency before clouds rolled in. Jupiter was only 20 degrees when I took this image.

Note a tiny part of Callisto's shadow on the SW of Jupiter. The SEB looks reddish on this region. The NEB has a very dark red color.

Finally imaged an old friend. Jupiter was just 24 deg altitude when I took this image. Seeing was terrible and I had to image though clouds! And I had to race against the rising sun!

The GRS is setting on rhe right. The wake of the GRS is very active yet the SEB is still very pale. Note the white feature on the NEB at the CM. The NEB seems to be slowly regaining its red color. Is revival on the way?
