JUPITER 2023 SEASON

By Christopher Go

All images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount.  A QHY5III678M and a QHY5III585C camera  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 2.7 64bit software.  All images are NORTH UP!     Processing was done using AutoStakkert! and Registax.

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

March 5, 2024

Conditions were very unstable today because I had to image during twilight.  Seeing was bad because of the hot roof of my house.

The GRS is prominent in this image.  Is has become very round now rather than an oval shaped spot!  The chimney above the GRS seems to be open.  Note the bright white band preceding the GRS.  The NEB looks quiet in this region.

 

March 3, 2024

Seeing was very unstable today. 

The GRS is setting on the right.  The wake of the GRS is very complex.  But not significant outbreak today.  The NEB looks quiet in this region.

March 2, 2024

I finally had a clearing.  But seeing was horrible with Jupiter getting very low. 

Oval BA can be seen as a very faint orange ring.  The NEB looks active on the right.

February 22, 2024

Weather here had been very bad this month.  I finally got a few minutes of clearing before the sky became overcast.  Seeing as very unstable and I had to image during twilight.

The GRS is rising on the left.  Oval BA is on the right.  The NEB looks quiet in this region.  Ganymede is on the upper right.

February 9, 2024

The NE monsoon has really affected our region.  Nothing but clouds and rain for the past week.  I had a short clearing today before the sky became overcast again.  Seeing was very unstable.

Something seems to be brewing on the STrZ.    The NEB shows complex rifts but no outbreaks.

February 2, 2024

Weather here had been horrible due to the NE monsoon.  I finally had a short clearing today.  Unfortunately seeing was very unstable.

The South Polar Red Spot can be seen in these images.  The SEB looks very quiet.  The NEB shows a lot of complex rifts.  There are no outbreaks at this region.

 

January 21, 2024

The sky was mostly overcast today.  I had a very short clearing but had to image though clouds.  Seeing was fair but transparency was poor.

Ganymede's shadow can be seen close to the south pole.  The south polar red spot can be seen to it's right.  The NEB shows some complex rift activity.

 

January 17, 2024

The NE monsoon has finally hit our area.  We had a week of clouds and cool weather coming from the northern Pacific.  I finally had a break today.  But seeing was very unstable due to powerful gusts.

The GRS shows some flaking activity.  The hook like feature NW of the GRS is very prominent.  This feature seems to be a barrier that prevents the wake of the GRS from spilling to the other side of the SEB.  The chimney above the GRS is open.  The wake of the GRS is looks very chaotic.

 

January 11, 2024

Seeing was good today but I had to deal with clouds.

Io is in transit above the SEB.  It's shadow is following on the left.  Note the large white ovals on the NEBn.  There are large white ovals visible close to the north pole.

 

January 10, 2024

Conditions were good today.

The GRS is well resolved in these images.  There seems to be some flaking on the left side of the GRS.  The wake of the GRS is very chaotic with multiple outbreaks.  Oval BA is clearly red.  The NEB is still very active with complex rifts.  Ganymede be seen on the upper right of Jupiter.

 

January 9, 2024

I had a late imaging run today.  Seeing was good.

Oval BA has turned red again.  It has become dark again in the blue and green channels.  Red Spot Jr is back!  The cyclonic systems on the belt below Oval BA looks very interesting.  The NEB is very active here with very complex rifts and outbreaks. 

 

January 8, 2024

Seeing was a bit unstable when started imaging but as Jupiter got higher.

The GRS can be seen on the right.  The wake of the GRS is very chaotic and has a lot of outbreaks.  The NEB in this region seems to be widening.  Note the "ghost" like feature on the NEBn.  There is also a cyclonic circulation with two dark barges inside at the NEB just past the CM on the first image.  There are north polar details resolved in these images.

 

January 5, 2024

Seeing was a bit unstable today. 

Oval BA has a distinct orange color.  It is getting dark in the blue channel. Will it become a red spot again.  The GRS is well resolved in these images.  There seems to be some flaking on the western edge.  The "chimney" above the GRS is close.  The wake of the GRS looks chaotic.

The NEB shows some bright outbreak like features but these are not bright in methane band.

January 4, 2024

Conditions were perfect again today. 

Note the large oval feature on the north pole.  The NEB shows complex rifts.  The south polar red spot can be seen rising on the left.

January 3, 2024

Conditions were good today. 

The wake of the GRS can be seen on the right with the GRS setting on the right.  Europa's shadow can be seen in transit.  The NEB shows complex rifts.

 

January 2, 2024

Conditions were perfect today.  I had 10/10 seeing!  Jupiter was so still this evening!

The south Polar Red spot is prominent on these images.  The SEBn show complex waves of clouds.  A part of these features are bright in methane band.  The NEB shows complex rifts and some outbreaks.

January 1, 2024

Happy New Year!  Here are my first images of 2024!  Conditions were perfect today.

The NEB is very active.   Note the very dark cyclonic oval on the NEBn just past the CM.  The dark festoon on the NEBs at the CM is very dark in methane band.  The right side of the SEB shows the wake of the GRS.

 

December 31, 2023

It's New Year's Eve here.  This will be my last image for 2023.  Happy New Year!  Conditions were very good this evening.  Although there was times when seeing dropped to only 8/10.

The GRS is well resolved in these images.  The chimney above the GRS seem to be closing again.  The wake of the GRS is very chaotic.  Oval BA clearly has an orange. The NEB is very active in this region with bright outbreaks and complex rifts that can also be seen on the methane band images.

 

December 30, 2023

Seeing was excellent this evening.  But I had to deal with clouds and poor transparency when I stared imaging.  During my second run the sky was clear so the image is better.

The north polar hood visible in methane band is not as extensive as before.  Spots on the north pole are clearly visible on the methane and image.  The NEB has some active outbreaks and complex rifts.  The white spots on the NEBn are bright in methane band.  Note the interesting feature on the STB at the CM on the last image.  Looks like a congregation of cyclonic features.

 

December 28, 2023

Conditions were a bit unstable today. I had to image early because I'm going tonight to attend a reception.

The small bright outbreak on the NEB is bright in methane band.  The NEB shows a lot of rift activity.

December 26, 2023

Merry Christmas!  I finally had a period of clear skies this evening.  It was very windy which affected the quality of my data.  I was hoping to image the GRS, unfortunately clouds rolled in and the sky was overcast again.

Here is an image of Jupiter with Io in transit at the SEB.  The light orange Oval BA is below Io.  The center of Oval BA has a very pale orange color.  The GRS is rising on the left.  The NEB is showing some complex rifts.

 

December 22, 2023

I was hoping to image the GRS today but it was cloudy early this evening. When the sky cleared, the GRS was already setting.  Conditions were perfect today.

The wake of the GRS is prominent in these images.  Note the multiple outbreaks on the wake.  This can easily be seen in the methane band image.  The NEB is also active with complex rifts.

 

December 21, 2023

After a few cloudy days due to a tropical cyclone, we finally have some clear skies. Seeing was excellent today.

There is a bright outbreak on the NEB.  This area seem to be very active lately with outbreaks erupting every few days.  The south polar red spot can also be seen.

 

December 16, 2023

Conditions were unstable today because I had to image early.  A tropical cyclone is headed our way and I am still trying to decide if I should take down my C14 now or try to get an image tomorrow. 

Ganymede is well resolved in these images!  This is around the same area that I captured yesterday.  The outbreak I imaged yesterday is still there but not as bright.

 

December 15, 2023

The sky was mostly cloudy early this evening as the outer rain bands of LPA 91 has reached Cebu. SEEing was a little unstable.

There is a small outbreaks on the NEB.  Above this outbreak is a large white oval with a blue haze.  Note the large gray feature on the SEB.

 

December 14, 2023

The sky was mostly cloudy this evening.  I went out to attend a Christmas party with friends.  But have to leave early to capture these images.  Seeing was excellent!  These images were captured using the QHY5III585C camera.

The GRS is prominent in these images.  It is well resolved with details visible inside the GRS.  The chimney above the GRS is open.   The part of the SEB preceding the GRS has a very dark red color.  Oval BA's light orange core is very prominent.  Oval BA is not very bright in methane band.  In the 850nm IR pass image below, one can see a dark band on the south pole of Jupiter. 

 

December 13, 2023

Conditions were poor today.  Seeing was variable and I had to image though clouds!

Note the large white oval on the NEB.  There is an interesting dark cyclonic feature on the STB close to the CM of the second color image.

December 12, 2023

It was mostly cloudy when I started imaging.  I had to wait out for the clouds to clear.  Seeing was excellent when I started but it dropped to 8/10 towards the end of my imaging run.

The GRS can be seen on the left.  The chimney above the GRS is open.  The wake of the GRS is very turbulent with a very bright outbreak.  There is also a huge bright outbreak on the NEB. 

 

December 11, 2023

The sky was mostly cloudy early this evening.  When I started imaging, I had to image between clouds.  But the sky where Jupiter was cleared up.  Seeing was quite good today when the sky cleared up.

This is the region preceding the GRS.  The red spot close to the south pole can be seen here.  The SEB is quiet in this region while the NEB shows some small outbreaks and complex rifts.  At +47N (at the CM on the second color image), there are two small ovals basically kissing!  Will these ovals merge?  There is a weird rectangular feature between the two SSTB ovals

December 10, 2023

Conditions were unstable today.  Seeing and transparency was variable.

The GRS is well resolved in these images.  The dark core can be seen.  Note the complex wake of the GRS and the bright outbreaks embedded on the wake.  There is also a very bright outbreak on the NEB.  Note the dark band forming on the STB which seems to be created by the wake of Oval BA.

 

December 8, 2023

Conditions were challenging today due to clouds.  Transparency was poor.

There is a tiny outbreak on the NEB.  Note also the red spot on the NEBn above this outbreak.  This feature looks like a mini GRS on the NEB. 

 

December 7, 2023

I had a late imaging run today.  I was doing an outreach for a local university.  Seeing was unstable when I started imaging but improved when the sky cleared.

The GRS is setting on these images.  The chimney above the GRS is open!  There are complex outbreaks on the wake of the GRS.  The NEB is also active with rifts and some outbreaks.

 

December 4, 2023

Conditions were perfect today.

The little red spot close to the south pole is very prominent in these images.  The color is intense!  The NEB shows some outbreaks and rifts.

 

December 3, 2023

Conditions were unstable when I started imaging but improved when Jupiter got higher.

This is the region after the GRS.  The NEB looks like it is reviving.  I wonder if this is a permanent revival or will this fizzle out.  The wake of the GRS can be seen here.  There are complex rifts on the NEB.  Note the huge dark red feature on the NEBn rising on the left.  Io is transiting on the SEBs.

December 2, 2023

Conditions were challenging today.  I had to image between clouds.  It was also very windy.

The GRS is well resolved with the three small ovals on the east side of the GRS.  The wake of the GRS is very turbulent.  Note the long white streak NE of the GRS.  The light orange center of Oval BA can be seen.  Europa's shadow is close to Oval BA.  The NEB shows some complex rifts from the interactions of the EZn festoons.  Above the NTB on the first image there is a bright streak with a dark borderat the CM. 

November 30, 2023

The sky was mostly cloudy most of today.  There were some clearing early in the evening but transparency was very poor.  Seeing was however excellent.

Here are images of the GRS.  Three small ovals are resolved inside the GRS.  The wake of the GRS shows some bright outbreaks.  Oval BA light orange ring can be seen.  The chimney above the GRS seem to be closing again.

The NEB is very active in this region with multiple bright outbreaks.   These outbreaks are however not bright in methane band.  Close to the north pole, there seems to be huge white feature.

 

November 27, 2023

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

These images show the GRS and Oval BA.  The GRS continues to shrink.  Note the reddish streak on the STrZ preceding the GRS.  The chimney above the GRS is open. There is a bright outbreak on the wake of the GRS. val BA shows a light orange core.  The NEB is active in this region especially on the southern part with the interaction with the festoons.

 

November 26, 2023

Conditions were perfect today.  I did a test with the QHY5III678M.  I did not use binning nor drizzling for the image.  I also had to use my SSD instead of my HDD because my HDD couldn't keep up with the data.  The rest of the images were taken using the QHY5III585C.

The NEB and SEB looks quiet in this region.  But a lot of details are resolved.

 

November 24, 2023

It rained hard late this afternoon to early evening.  The sky cleared when Jupiter was close to the zenith.  Seeing was excellent but it was very windy.  Seeing deteriorated as the winds got stronger.

The NEB and SEB looks quiet in this region.  Note the strange feature above the NTB before the CM. 

November 23, 2023

Conditions were excellent today.  I started early today to capture the GRS.  I had to use a mono camera because Jupiter was only around 45 deg above the horizon.   I switched to the OSC camera as Jupiter got higher.

The GRS is well resolved in these images.  A lot of details are resolved inside the GRS.  Oval BA seems to be turning red again as it regains it's orange core.  The SEB following the GRS show a lot of outbreak activity.  These can clearly by see in the methane band images.  The second color images shows the approximate area where Juno will make an equatorial pass during PJ56.  The NNTZ LRS shows is small orange call much like Oval BA.

 

November 22, 2023

Just came back from my trip to China where I attended the 5th Yangtze River Delta Star Party.  The sky was overcast all day but cleared this evening!  Seeing was excellent but transparency was poor.

The GRS and Oval BA are rising on these images.  There are three bright outbreak spots on the NEBs.  However they are not bright in methane band.  Note the small white spots on the SEBs.

 

 

November 14, 2023

It was mostly cloudy today.  The sky cleared early this evening.  After taking some images, clouds started to roll in.  Seeing was quite good.

Here is an image of the other side of Jupiter.  The NEB shows a lot of complex rifts.  The SEB shows the normal turbulence from the GRS.

 

November 13, 2023

We had some rain early this evening.  I was surprised that the sky cleared.  Seeing was good but it was very windy.

Here are images of Jupiter with the GRS and Oval BA.  The dark red core of the GRS is resolved.  The chimney above the GRS is close while there are two bright outbreaks on the wake of the GRS.  Oval BA is now moving away from the GRS.  The orange core is now distinct.    There are some activity on the NEBs above the GRS.  In this area there is a very bright outbreak interacting with the dark feestons.

 

November 12, 2023

Seeing was mostly good today.  On the last two color images, there is a comparison between a mono camera (QHY5III678M) and a OSC camera (QHY5III585C)

The most interesting object in these images is the very bright bluish spot on the NEBn.  Despite its bright appearance, it is dark in methane band.  It is rather interesting that on the STB, there are dark spots lining up while on the NTB there are small bright spots lining up.  A lot of details are resolved especially in the area close to the poles.

 

November 10, 2023

Conditions were variable today. Seeing was sometimes good.  At other times, it was unstable.

The GRS is well resolved in these images.  Note the small white spot above the GRS on it's halo.  A pale orange ring can be seen inside Oval BA.  In methane band, Oval BA is not as bright as the GRS.  The wake of the GRS is very active.  The NEB looks quiet in this region. There seems to be some bright outbreaks but these aren't bright in methane band.  The NNTZ LRS can also be seen.

 

November 9, 2023

I had to image early today because I wanted to sleep early.  Jupiter was still a bit low in the sky so seeing wasn't great.  These were capture with the QHY5III678M camera.

The NEB looks active in this region.  There are many rifts and outbreaks.  The contrast between the SEB and NEB is striking in the methane band image.  The SEB looks quiet in methane band while the NEB looks very active.  The NTB is just a think reddish/purple band on the color image but in methane it is a full belt!  The north polar hood  has extended south in the methane band image.

 

November 8, 2023

It was cloudy all day but the sky cleared this evening.  Seeing was good but transparency was poor due to some thin clouds.

The GRS and Oval BA are prominent in this region.  A pale orange core of Oval BA is resolved.  The wake of the GRS is very turbulent with complex outbreaks.  On the south side of the GRS, there seems to be some mixing with the materials on the wake of Oval BA.  Strangely, the area on the STB preceding Oval BA is clear.  There are some outbreaks on the NEB but these aren't bright methane band.

In methane band, there is a dark feature on the northern end of the south polar hood.

November 6, 2023

 Conditions were good today. But I had to cut short my imaging run as rain was approaching.   These images were taken using the QHY5III678M camera.

 The GRS is setting on these images.  The wake of the GRS is very complex with very bright outbreaks.  The NEBs also shows some bright complex outbreak.

 

 

 

November 5, 2023 PART II

 I had another run today to image the GRS and Oval BA.  Seeing was very good with Jupiter at the zenith.  Seeing was so good that only light post processing was necessary.  I will be using the mono camera in the next few days because of the request by those involved with the Juno spacecraft to capture very high resolution images of Jupiter.  After imaging with a color camera for the last few months, it took time to get use to how high contrast the images from mono cameras are.  Contrast enhancement is not necessary anymore. 

Oval BA has just passed the GRS.  The center of Oval BA has formed a pale orange color.  The wake of the GRS is active with outbreaks.  There is a very bright outbreak on the NEBs.    The NNTZ Little Red Spot (LRS) can also seen in these images.

 

November 5, 2023

Conditions were perfect today.   My routine now starts with a mono capture then capture the methane band and a Luminance set with the color camera.  This will be part 1 of today's imaging run.  If the sky continues to be clear, I will capture the GRS later.

This is the region preceding the GRS.  The south polar red spot is very prominent in these images.  Note the long pale yellow cloud on the NEBn just past the CM.  The SEB shows the turbulence from the GRS.

 

November 4, 2023

It was cloudy all day today.  But the sky cleared close to midnight.  Seeing was excellent with Jupiter close to the zenith.  My first image was captured using a monochrome camera (QHY5III678M) and the second image was made using a color camera (QHY5III585C).

The NEB and SEB looks quiet in this region.  The southern hemisphere is pale in this region.  In fact except for the dark band it seems the the southern hemisphere have lost it's belts!  The northern hemisphere has a more reddish color compared to the southern hemisphere. 

 

November 3, 2023

It's the day after opposition.  It rained hard this evening!  I was about to give up but the rained stopped for a few minutes.  So even with the ground wet, I attempted to image Jupiter.  Seeing was good but transparency was very poor as I had to image through clouds.  After imaging methane band, I had to rush and take down my system as rain was coming!

The GRS is prominent in these images.  The wake shows a complex outbreak.  Ganymede can be seen on the south pole.  Many features are resolved.  The shadow of Ganymede is now following the planet  because we are just past opposition.

 

November 2, 2023

Jupiter is now at opposition!  Conditions were perfect today.  For the color image, I tested the mono cam (QHY5III678M) vs the OSC (QHY5III585C).  The monochrome camera gives a much better image with a lot of low contrast details no seen on the OSC.

A lot of fine details are resolved in these images. Note the tiny dark cyclones lining up on the STB.  The NEB shows some complex dark features around the CM.

 

November 1, 2023

Conditions were perfect today.

The GRS and Oval BA are in conjunction right now.  Oval BA is very pale.  There is even a third white spot on the SSTB that has joined the conjunction party!  The wake of the GRS is very active with some complex outbreaks.  The NEB has a bright spot but this is not bright in methane band.

 

October 31, 2023

The sky was partially cloudy today.  Transparency was poor as I had to image through clouds.  Seeing started average but improved later on.  We are two days before Jupiter opposition!

Europa and it's shadow is very close to each other!    The south polar red spot can be seen below just past the CM.   The NEB has some interesting features especially the large grey area just before the CM.

 

October 28, 2023

I am finally back home from my trip to the USA for the Annular eclipse earlier this month.  Seeing was perfect!

The south polar red spot can be seen n these images.  Note the small outbreak spots on the NEBs.  These are not very bright in methane band.  The north polar hood is not very bright in methane band.

 

October 5, 2023

Conditions were incredible today after weeks of terrible weather due to Typhoon Koinu.

Oval BA is about to have a conjunction with the GRS!  Oval BA has become very pale.  The orange ring it had before is gone!  But there is a small orange spot in the center!  One can see how small the GRS has become when compared with Oval BA.  There is a bright outbreak in the wake of the GRS.

Note the small outbreaks on the NEBn.  Many of these are bright in methane band. The NNTZ LRS can also be seen.

 

September 19, 2023

Perfect conditions today!

The NEB has a lot of rifting.  Note the huge dark elongated object on the NEB after the CM.  There is also a small red spot the lower center of this object.   In methane band, there is a bright object on the EZ next to a dark festoon at the CM.  The SEB shows the turbulent wake from the GRS.  The STB shows some dark cyclonic features.  These are well resolved in the methane band image.   The south polar little red spot can also be seen.

 

September 15, 2023

Conditions were perfect today.  I didn't really have to do a lot of post derotation sharpening.

The GRS has really shrunk!  It's so small now.  The core of the GRS is resolved. The wake of the GRS continues to be very active.  The "chimney" above is open.  Oval BA's pale orange ring is well resolved.  The NEB seems to have a grayish haze over the complex rifts.  The NNTZ LRS is prominent with its reddish core.

September 10, 2023

Seeing was variable today due to monsoon winds.

The GRS is prominent in these images.  The chimney above the GRS is open.  The wake of the GRS has some bright outbreaks.  Oval BA can be seen rising on the left.  The orange ring is resolved.  The NEB is quiet in this region.  The NNTZ LRS can be seen rising on the upper left.

September 7, 2023

Conditions were perfect today.  I used the QHY5III585C camera for these images.  This camera is very low noise and produces incredible images up to NIR!

A wealth of details are resolved in these images.  The South Polar Red Spot can be seen below.  The NEB shows a large cyclonic oval on the CM.  Two bright spots came be seen on the NEB but these are not methane bright.  Also in methane band, the haze on the north pole is very faint!   Io's shadow is in transit on the SEB.

August 31, 2023

Conditions were excellent today.  These images were taken using the QHY5III585C camera.

Io is well resolved and can be seen on the SEBs past the CM.  Using the Winjupos satellite derotation option really works!  The SEB in this region looks chaotic.   The GRS is rising on the left.  The NEB is dark and narrow. 

 

August 25, 2023

I was finally able to collimate my OTA last night.  It had been off since took it down when I travelled to the US last month.  Unfortunately, weather here had been very bad for weeks!  Seeing was average today.

The NEB and SEB looks quiet in this region.  Note the dark band on the STB which seems to be created by the wake of Oval BA.

 

August 22, 2023

Finally some decent conditions. 

The GRS has really shrunk!  Note the reddish right on the outer perimeter of the GRS.  There are two bright outbreaks on the wake of the GRS.  Oval BA is well resolved. Note the orange ring inside Oval BA.

 

August 14, 2023

The sky was hazy today but seeing was good.

The GRS is rising on these images.  The SEB and NEB are very dark.   Note the light elliptical features on the NEB just past the CM.

 

August 7, 2023

Conditions were poor today because of the SW monsoon winds. 

The GRS is prominent in these images.  There is a bright outbreak on the wake of the GRS.  The NEB looks quiet.

August 5, 2023

Conditions were very poor today. 

The GRS and Oval BA can be seen in these images.  The GRS has really shrunk!

 

August 3, 2023

Conditions were mostly good today but there were some thin clouds.  I note refocus when imaging IR and CH4 and the results are much better than the images yesterday.

Oval BA is setting on the right.  Note the red band on the STB following Oval BA.  The NEB and SEB shows the usual activities.

August 2, 2023

Conditions were perfect this morning.  Here are images of Jupiter without a barlow.  Yesterday, I tried using the Seibert 1.3X barlow and found out that the image scale was still too much. 

The GRS is rising on the left.  There is a bright outbreak on the NEBs.  In methane band, there are bright patches on the EZ.   There is a large grey oval feature on the NEB at the CM.

 

August 1, 2023

Murphy struck today.  As I was preparing for imaging, I noticed that the plastic screw of my Telrad finder was broken!  I had to use the C14 Finderscope today.  As I was able to image, I noticed that the USB wasn't running at full frame rate.  I had to restart my system.  As I was ready to image, thin clouds started to appear!

Note the two bright outbreaks on the NEBs at the CM.  The SEB looks quiet.

 

July 31, 2023

It has been over a month since my last image.  I finally had clear skies today.  But condition was terrible due to the SW monsoon winds.

The GRS is prominent in these images and has shrunk!  The size of the actual red spot is small compared to the halo.  The wake of the GRS is active.  Oval BA can be seen rising on the left and it looks very white.  The NNTZ LRS can also be seen and is the prominent methane bright spot in the northern hemisphere.

 

 

July 1, 2023

Seeing was excellent today but transparency was very poor.  I had to image through clouds. 

The NEB has complex rifts and a bright spot past the CM.  The huge cyclonic feature on the NEB can be seen rising on the left.  The SEB is quiet in this region. 

 

June 26, 2023

Weather had been terrible here.  I finally had a clearing but seeing was a bit unstable. 

Note the dark red spot on the NEB just before the CM.  This cyclonic spot is pushing against the large white spot on the NEBn. It is interesting that the area below that red spot is bright in methane band.  There is also a bright spot on the NEBs but this feature is not bright in methane band.  The SEB is quiet in this region.

Conditions were better this morning.  Seeing was ok despite the low altitude of Jupiter.

Not the huge cyclonic feature on the NEB just past the CM.  Note a white spot SE of this feature.  This feature seems cyclonic as it doesn't appear bright in methane band.  It is also a bit unusual as we don't really see a lot white spots at this latitude.  The SEB looks calm.

The methane band image below is impressive.  It shows how sensitive the QHY5III678M is in NIR.

Conditions were very poor today due to clouds and unstable seeing.

Here are images of Jupiter with the Oval BA.  The SEB and NEB are quiet in this region.  There is a large dark red cyclonic spot on the NEB at the CM.

Conditions were very good this morning.  But I was imaging very close to sunrise.   Jupiter was only 35 deg.

The NEB is very active in this region.  Note the two dark features on the NEB one before the CM on the NEBn (2 small red spots seem to be colliding there) and the other after the CM bordering the EZ.  The SEB is quiet in this region.

Finally some decent images of Jupiter.  Seeing was better today but transparency was very poor due to clouds.  I was not able to capture a methane band image because the sky was already overcast!  Jupiter was only 35 deg above the horizon!

The GRS is setting on the right.  The wake is very active.  Oval BA can be seen on the left.  It is still pale but a little shade of orange.  The NEB is narrow in this region.  Note the bright spot on the NEBn.  NE of the bright spot is a reddish extension to the NTrZ.

The weather here had been horrible during the last few weeks.  I finally had a clearing today but I overslept.  I could only take these images of Jupiter.  When I started imaging the conditions were horrible that I had to trash these data set.  The seeing improved as Jupiter got higher but now it is a race against the sun!  The methane band image was a bit challenging because the background was already very bright with the sun rising a few minutes later.

There is a bright oval feature on the NEB rising on the left.   Both NEB and SEB seem to have fully revived.  There is a large white oval on the STB.

This is my first image of the seeing.  Seeing was terrible because Jupiter is so low in the sky.  The GRS can be see in this image.
