JUPITER 2022 SEASON

By Christopher Go

All images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount.  A QHY 290M and a QHYIII462C 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.

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.

 

May 12, 2022

 

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.

May 11, 2022

 

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?

 

May 5, 2022

 

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.

April 30, 2022

 

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.

 

April 29, 2022

 

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.

 

April 23, 2022

 

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.

 

April 22, 2022

 

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?
