June 20,
2018 We had heavy monsoon rains during the last few days. I was not expecting much tonight because it was overcast all day. I was surprised that the sky cleared up a bit! It was still hazy and the seeing was poor. This is a quiet region of Jupiter. The STB Spectre can be seen but it is very fain and not very dark in methane band. The SEB and NEB looks quiet.
|
|
June 15,
2018 We still got the SW winds today enhanced by a tropical depression east of Luzon. This brings poor conditions here. Seeing was unstable but the sky was clear. This is a quiet area in Jupiter. The EZ has a strong yellow color. The NEB and SEB looks quiet here. The dark remnant of the STB Ghost can be see past the CM.
|

May 31,
2018 I wasn't sure I could image today. The sky was overcast all day. Even when I took these images, these were done through clouds. Seeing was variable and transparency was poor. I had some visitors today. Erika and Mark Rivera were with me along with Lowie Dino. Oval BA is prominent in these images. The STB Ghost has become dark and seems to be elongating. Note the merged SST Ovals setting on the lower right. There are now multiple outbreaks on the NEBs. |

May 28,
2018 Poor conditions today. I was not planning to image because the sky was overcast. The clouds thinned but never cleared. Seeing was okay but transparency was horrible due to clouds. The GRS is setting on the right. The wake of the GRS is very turbulent. Oval BA is rising on the left. The two merged ovals have almost done merging. The NEB looks quiet in this region.
|
|
May 27,
2018 Frustrating conditions today. Seeing was good and the sky was mostly clear except for a big patch of thing haze around the moon and Jupiter. I waited for over an hour for the haze to clear but it stayed stationary. So I just went ahead and took as much images as I could until the haze became a cloud. The STB Spectre can be seen just before the CM. The NEB seems to be fading in this region.
|
|
May 26,
2018 Seeing was fair today. Many interesting things in Jupiter. The most prominent feature is the red Oval BA. There is also a merged oval on the SSTB. It is the deformed white feature on the ESE of Oval BA. There is very bright feature in the methane band on the EZ. I have imaged this feature 2 days ago. Is it associated with the white spot on the the EZ? The NEB looks quiet in this region.
|
|
May 24,
2018 Seeing was fair when I started imaging. After my first run, clouds rolled it. I decided to wait the clouds out and took a second round of images. Seeing was much better during the second round. The north polar area of these images are the approximate area Juno would have imaged during it PJ13 close pass 1 Jupiter orbit ago. Note the while spot on the north pole. Oval BA is setting on the right on the first image and the complex remnant of the STB Ghost can be seen. There seems to be some bright outbreaks on the NEB but these are not bright in methane band. There is a very methane bright feature on the EZ but can't seem to associate it with a interesting feature on the color or IR image.

2018 I had an interesting imaging run today. When I started imaging, it was very hazy and transparency was poor. The haze slowly dissipated. As I was doing my 2nd run, thunderclouds appeared out of nowhere! Seeing was fair today. The GRS is well resolved in these images. The STrD is still pushing towards the GRS. The wake of the GRS is very turbulent with multiple outbreaks. The methane band image of this wake looks very interesting. The South Polar Red Spot can also be seen below the GRS. There is a bright outbreak on the NEB.
|

May 22,
2018 The sky was hazy today. Seeing was excellent but transparency was poor! These images show the region which Juno will see on PJ13 on May 24. The STB Spectre is distinct. The SEB shows the dark red barge preceding the GRS. The NEB seems to be losing most of it's red color. Note the bright reddish feature on the NEBs at the CM of the first image. This outbreak is very bright in Methane Band. Lots of features are resolved up to the poles!
|

May 20,
2018 The sky was mostly overcast today. Looking at the satellite image, things looked hopeless here. But at around 10pm local time, Jupiter was able to get through the clouds. Seeing was good but transparency was very poor. I had to crank up the gain and capture a lot of data to get this image. 17 min of data was captured to get this image. The GRS is rising and the dark core is resolved. The wake of the GRS looks active and the STrD can still be seen. The south polar red spot can be seen below the GRS. There seems to be some new outbreaks on the NEB.

May 19,
2018 I am back from my 2 weeks trip to Europe to attend the RAS Europlanet Juno Conference in London. I was an exciting trip and I was glad to meet many fellow imagers and the Juno team. I also had an accident in London. Seeing was close to perfect this evening. Oval BA is passed the CM. The STB Ghost has evolved into a complex system. Will the interaction of the STB Ghost and Oval BA revive the STB? The SEB and NEB looks quiet in this region. The methane band image is very interesting as it resolved a lot of polar details.
|
|
May 2,
2018 The sky was overcast today. I almost gave up on imaging but at around 10pm, Jupiter was able to pierce through the clouds. Transparency was very poor. Normally I would have gone to bed. But this will be my last chance to image before I leave for Europe for the Juno Conference. So I derotated the hell out of this image. I took as much image as I could using crazy gain settings until the clouds won over! Seeing was fair at around 6-7/10. The red Oval BA is setting on the right. The shape of the STB Ghost seem to have evolved. There a large reddish elongated feature on it. The NEB is quiet in this region.
|

2018 I had an incredible run this morning. Seeing was literally out of this world! Just incredible details on Jupiter from pole to pole. The red Oval BA is the highlight of these images and shows details resolved! The STB Ghost continues to push towards Oval BA and there is a small red spot at the very left of the STB Ghost. There is also another Polar Red Spot south of Oval BA. This is the second Polar Red Spot on Jupiter right now with the other spot south of the GRS. The SEB is chaotic as this is the region of the wake of the GRS. White Spot Z has returned to white again.

2018 I had one of those nights when nature seem to be playing tricks on me. The sky was clear when I woke after. After I set up my imaging system, a small cloud appeared around the area of Jupiter. This cloud grew until it covered a quarter of the sky! I was about to give up when 20min after, the clouds slowly vanished! Seeing was variable and transparency was poor due to haze. The STB Ghost is has become dark and looks very chaotic. There is a small red spot embedded on the STB Ghost at the CM of the first color image. This feature is bright in methane band. There is also a very dark barge close to the South Polar Region. The SEBn shows the turbulent wake of the interaction of the GRS and the STrD. The NEB is quiet in this region.

March 19,
2018 I was not sure I could image today. Accuweather predicted cloudy skies and a chance of showers. True enough, when I woke up at 2am local time, the sky was overcast! I went back to sleep. I had a hard time sleeping so I went back out at around 2:45am and found the sky clear! Seeing was horrible during the start of session. I had to discard a most of my data today. But seeing improved about 40min after I started imaging. Seeing was still not great. Oval BA is at the edge on the right. The STB Ghost is now a complex of small white ovals and some dark material. Note the dark band on the STrZ/STB border. The SEBn is turbulent while the NEB is quiet in this region.

March 15,
2018 Condition was variable today but with periods of good seeing. Humidity was a bit high which made imaging a challenge. However, these are some of my best images this season. The GRS is well resolved. Two small ovals can be seen INSIDE the GRS. In the methane band, there is a dark arc inside the GRS along with a very bright area in the middle. The STrD is still pushing towards the GRS. The small dark feature following the STrD is moving closer to the GRS! The wake of the GRS is very turbulent. The South Polar Red Sot is prominent. There is a bright rift on the NEB but this feature is not bright in methane band. However there are two bright plumes in methane band at the EZn/NEBs border that seems to be pushing close to each other. Will these merge? These two bright plumes are not very clear in the color image because of the EZ festoons.
|
|
March 13,
2018 We had rains and clouds during the last few days. It finally cleared up this morning. Seeing wasn't great though. The STrD is still pushing towards the GRS. Note the large dark feature on the STrZ following the STrD. The wake of the GRS is very turbulent. The South Polar Red Spot can also be seen SSE of the GRS. The NEB is quiet in this region. Note the two bright area on the NEBs/EZ just before the CM. These two features are bright in methane band. Europa is the moon just off Jupiter.

March 1,
2018 I woke up early today excited to catch the GRS. But this morning was one of those days when I first thought that maybe my telescope is broken. Then you realized that I probably should have gone back to bed. Seeing was so bad because of NW winds. 90% of my data was just muk! These images show the GRS. The STrD is now pushing had towards the GRS. The wake of the GRS is very turbulent!

2018 I woke up at 3:50am today. When I went out the sky was overcast! But there seemed to be some clearing on the horizon. I went back to sleep and was back at around 4:30am. Still overcast but with some winds and hope of clearing. I gave up at around 5:00am At 5:30am, the sky cleared ! I rushed to image! Seeing was good due the the East winds. But it was a race against the sun. The CH4 image was taken a few minutes before sunrise! These images show Oval BA and the STB Outbreak remnant on the STB Ghost. The STB Ghost is still dark in CH4 but the bright outbreak is now mostly gone. The STB Ghost is moving closer to Oval BA! Will we see fireworks when they collide? Note the brightening on the EZn. The NEB still shows the wave pattern on methane band.

2018 Happy Lunar (Chinese) New Year! Condition was a bit frustrating this morning. Seeing was variable. But I had a double whammy of thin clouds causing variable transparency and dew due to high humidity! I had to do some hard processing to get these images. Oval BA can be seen in these images. It still has a pale orange color. The STB Ghost has a dark arc due to a white oval right next to it. The STB Ghost is dark in CH4. There are some features resolved inside the STB Ghost which may be some remnant of the recent outbreak. The SEB shows the end of the wake of the GRS. The WSZ can be seen on the NEBn just past the CM.

2018 Poor and frustrating conditions today. We are having a cold front here with temperatures dropping to around 20C. Unfortunately, this system is bringing in NW winds to my location which is terrible for seeing here. Oval BA can be seen just past the CM. The outbreak following BA has really developed into a complex system. This system is embedded in the STB Ghost! Note the bright streak in the methane band image! Rising on the SEBn is what seems to be an interaction between the SEBn and the EZs. Festoons seem to be forming on the EZs! The NEB shows the wavy pattern in methane band.

2018 Condition was terrible this morning. Seeing was unstable and I could only salvage a few data. I was fortunate to capture the STB outbreak that was first imaged by Damian Peach and Anthony Wesley and noticed by John Rogers. The outbreak can be seen setting on the right and it is very elongated. It is very prominent in IR and can be seen in CH4 band . The CH4 band brightness is not as bright as when it first appeared. But the area preceding this outbreak is very dark in CH4 band! The SEB is quiet in this region. Io's shadow is on the NEB and note the wave pattern on the NEB.

2018 Seeing was again unstable today and transparency was variable. I had to use a lot of data to get the color image. This images show the wake of the GRS. The GRS has just set while Oval BA is rising on the left. Note the methane bright region on the SEBn. The NEB is quiet in this region. WSZ can be seen also rising. It still has a light reddish hue. Interestingly, the northern part of this spot is very bright in methane band.

2018 Seeing was unstable today because of the NW winds. But it became stable as Jupiter got higher. Transparency was variable. The GRS is prominent feature in this region. The GRS is well resolved especially on the second image. Outbreaks seem to be active in the area following the GRS. The SEB outbreak seem to be pushing the STrD towards the GRS. This will be interesting to see how this will develop. The NEB is quiet in this region. The South Polar red spot can be seen below the GRS.

2018 We had terrible weather during the last weeks. But this morning the sky was mostly clear when I started imaging. Unfortunately, clouds appeared out of nowhere so transparency was very variable! Seeing was stunning! Oval BA can be seen setting on the right. The STB Ghost is the bluish feature following Oval BA. The SEB clouds are well resolved. The dark barge on the SEB can be seen rising on the left. The NEB is shrinking! The northern part has basically lost its color. A lot of features can be resolved in the temperate zones.

2018 The sky was clear this morning. Seeing was good. Note the bright spot north of the dark barge on the SEB. Will this start an SEB outbreak? The CH4 image doesn't show any brightening so it is premature to call this an outbreak. We will see in the next few days if this feature will brighten up on CH4. This feature is currently located at around CM2: 185. Note the dark barge on the STrZ just southwest of the SEB red barge. The feature seems to show a "hump" on its surround belt. Nothing in the CH4 however. The NEB looks quiet in the region. There are some brightening close to the EZ festoons.

2018 The sky was mostly cloudy today. I probably should have gone back to bed because imaging was very frustrating with clouds passing Jupiter. The GRS and the South Tropical Disturbance (STrD) are prominent in these images. There seems to be some SEB outbreak north of the STrD. Io is the bright patch above the GRS on the NEBn.

2018 The sky was partially cloudy today with a bit of haze. I hesitated a bit to image because of the conditions. I was lucky to capture a set of RGB before the sky was overcast. Seeing was not great and transparency was very poor. The dark red barge with a bright halo on the SEB looks interesting. The NEBn has cyclones and anti-cyclones lining up. The NEBn is also light in color. Is the NEB shrinking this season? |

2018 Happy New Year! Here are my first images for 2018! Seeing was much better this morning. Though it is still poor compared to my usual seeing due to Jupiter being so low in the sky. Oval BA is prominent in these images. The light orange ring can be seen. The SEB looks turbulent in this region, while the NEB is not every active. White Spot Z can be seen on the NEB. It still has a reddish hue.

2017 Very poor condition today due to a nearby low pressure system. The SEB and NEB looks quiet in this region. The NEB looks very wavy in methane band.

2017 Condition still very unstable today. I had a clearing before an upcoming storm. A tropical cyclone is headed our way. Oval BA can be seen setting on right. Note the dark band on the STrZ. THe SEBn is dark. The outbreak that was seen last season seems to be gone. There are a lot of anticyclonic white spots on the NEB! Note the wavy look of the NEB in CH4.

2017 My first image of Jupiter this season. Seeing was a bit unstable because Jupiter was very low. I started imaging in IR and CH4. Unfortunately, when I was ready to image RGB clouds rolled in. This feature is prominent in the IR image. Note the dark wavy pattern of the NEB in the CH4 image.
