JUPITER 2017/18 SEASON

By Christopher Go

All images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount.  A QHY 290M camera was 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 2.5beta 64bit software.  All images are NORTH UP!     Processing was done using AutoStakkert! and Registax.

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

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.

May 23, 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.

 

May 1, 2018 

Seeing was mostly excellent today but there were periods where it was less than perfect. 

The GRS is well resolved.  The STrD continues to push towards the GRS.  Note the multiple outbreaks on the wake of the GRS!  The methane band image show 3 bright outbreaks.  The south polar red spot is very prominent.

April 30, 2018 

Seeing was variable today. 

The STB Spectre is very faint.  But its bluish features are clearly visible.   The dark red spot on the SEB is distinct.   Note the large white ovals on the NEBn.   The NNTZ LRS is prominent in the northern hemisphere.

April 29, 2018 

Condition was a bit challenging today.  The sky was mostly cloudy.  I had to take an image of Jupiter during gaps between clouds.  I was only able to get a few sets of data.  When I was about to capture the CH4 data, the sky was already overcast.   Seeing was very variable.

Oval BA is prominent in these images.  The red ring is well resolved.  The STB Ghost is very turbulent.  The White Spot Z can be seen past the CM.

 

April 27, 2018 

Seeing was variable today.  There some periods of good seeing but mostly mediocre seeing.

Oval BA is setting on the right.  The STB Ghost  is very complex.  The red spot on the STB at the CM of the first image looks interesting.   This spot is bright in methane band and is embedded in dark material.

The SEB and NEB looks normal.

April 24, 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.

April 23, 2018 

Seeing was variable today and mostly unstable.

The GRS is rising on these images.   The STrD continues to push though the GRS.  There seems to be a new outbreak on the wake following the GRS.  Note the SEBn/EZ area above the GRS is very bright in methane band.  The SEB dark red spot can be seen setting on the right.   The South Polar red spot can also be seen.   The STB Spectre is just past the CM.

The NEB is quiet in this region.

April 21, 2018 

Perfect conditions today.  Seeing started at only 8/10 but improved to 9/10 as Jupiter got higher in the sky.

Incredible details inside the GRS.  The dark core and the surrounding details are well resolved.   The STrD is very turbulent and the outbreak in the wake of the GRS is expanding.  The oubreak is  bright in methane band.  The South Polar red spot is very distinct.   A lot of details are resolved at the NEB and at the other regions of Jupiter.

April 16, 2018 

Seeing was excellent today!  My only problem was clouds which badly affected transparency!

The GRS is very well resolved.   The dark inner core and the vortex streaks can be seen.  These features are visible in the Juno images.  The bright outbreak on the SEB following the GRS is expanding.  This feature is bright in methane band.  The South Polar Red Spot is clearly seen.

April 14, 2018 

Seeing was variable this evening.  I had to image early to catch the GRS.   I also had to deal with some clouds.

The GRS is well resolved and there is a BRIGHT OUTBREAK following the GRS!!!    This outbreak is very bright in methane band.   The STrD is still following the GRS pushing into it.  The South Polar Red Spot can be seen below the GRS.  The NEBn is still very light in color.   Note the white and red spots on the NEB!

Europa and it's shadow are doing a transit over Jupiter.

April 9, 2018 

Weather here in Cebu has been crazy.  March and April are  suppose to be dry season here with Easterly Winds!  But we had nothing but clouds,  rain and Northerly winds which make seeing horrible!  Transparency was poor today and seeing was very unstable.

The GRS and the STrD are creating a complex wake!   It is interesting to note the the N edge of the GRS is bright in methane band.  The NEB is quiet in this region.

April 5, 2018 

Condition was poor today due the N winds. 

Oval BA and the STB Ghost are still interacting.  The wake of Oval BA is very turbulent. The NEB shows the WSZ just past the CM.  

April 3, 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.

April 1, 2018 

Seeing was below average today though we had perfectly clear skies.

This is the region Juno imaged during PJ12.  These images are 1 rotation after PJ12.  Juno imaged the area just to the right of the GRS.  The GRS is well resolved on these images.   The wake of the GRS is just chaos!   The STrD is violently interacting with the GRS.   The South Polar Red Spot can be seen SE of the GRS.  The NEB looks quiet in this region.

March 29, 2018 

Seeing was variable this morning.  Transparency was poor due to haze.

These images show the tail end of the STB Ghost.  The NEB has some bright outbreaks.  But it seems that the northern part of the NEB has lost it's color.

March 28, 2018 

Condition here has been terrible due to nearby Tropical Storm Jelawat.   Seeing and transparency was very poor.

The wake of the GRS is very chaotic.  The STrD must be pushing above the GRS now.   Note the multiple bright spots in Methane Band in the area following the GRS.  The southern rim of the GRS is very dark in Methane Band!  Ganymede can be seen on the lower left of Jupiter.

March 21, 2018 

We had a strong rain last night which flooded my veranda.  Fortunately, the sky cleared during the time Oval BA was at it's prime.  Seeing and transparency was variable due to thin clouds.

Oval BA's orange ring is clearly resolved.   The STB Ghost is quite a mess.  It's a mixture of dark material and small white ovals and this feature is still pushing toward Oval BA.  Note bluish feature on the p side of Oval BA.

The SEB shows the tail end of the turbulent wake of the GRS.   The NEB is quiet in this region.  White Spot Z has a brick reddish hue but it is not bright in methane band.

March 20, 2018 

I had some fair seeing conditions today. 

The GRS well resolved with a lot of details inside the GRS.  The STrD is thinning out as it pushes to the GRS.  The dark patch following the GRS is now hitting the STrD.  There are two bright outbreaks in within the wake of the GRS.  The South Polar Red Spot can also be seen SE of the GRS.

The NEBs/EZn shows some interesting interaction just past the CM.  The ice moon  Europa can be seen on the NNTZ.

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 18, 2018 

The sky was clear this morning.  Unfortunately, seeing was still  unstable.

The GRS is very well resolved.  The dark core can clearly be seen.   The STrD is still interacting with the GRS.  The South Polar Red Spot can be seen below the GRS.  The NEB is quiet in this region.  The methane band bright area on the NEBs/EZn is now covered with dark material. 

March 17, 2018 

It was a bit blustery today.  Seeing was variable this morning.

There were two shadow transit this morning.  The first shadow is that of Ganymede.  The second shadow is that of Io.  The SEB red barge had become round.  The NEB looks quiet here.

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 9, 2018 

Variable seeing this morning due to NNW winds.  There were periods of good seeing.  Transparency was excellent.

The red Oval BA is very well resolved.  The orange ring is distinct.  The STB Ghost is very close to Oval BA.  In the Methane Band, the N and NW of Oval BA is some dark material passing through.  Are these material from the STB Ghost? 

The NEBn shows the WSZ.  This spot us currently dark in Methane Band.   The NEB is quiet now and the methane band image shows the distinct wave pattern.

March 8, 2018 

The condition was a bit challenging this morning.  Seeing was very variable.  Sometimes it was stable, at other times it was horrible! Transparency was also variable due to thin clouds and haze.

The GRS and the South Tropical Disturbance (STrD) are still interacting.  The wake of the STrD seems to have thinned out as it pushes towards the GRS.  The wake of the GRS is very turbulent!  The South Polar Red Spot can be seen below the GRS.

The NEB looks quiet except for the bright rift.  In methane band, it looks quiet.

March 7, 2018 

Seeing was variable this morning with periods of excellent seeing.

Oval BA is setting on the right.  The STB Ghost is well resolved.  It looks very complex with dark streaks and small white ovals embedded.  This feature is very dark in methane band.

The NEB looks quiet in this region.  While the SEBn is still turbulent.

March 5, 2018 

I actually overslept this morning.  I was suppose to image at 3am local time but did not wake up till close to 5am.  I went ahead to image even though Jupiter was way past meridian.   Seeing was excellent during the start of my run.  Unfortunately, it deteriorated during my second RGB set.

The GRS is rising on these images.  There is only a hint of the STrD on these images.  The dark red barge on the SEB can be seen on the right.   There is a bright outbreak on the NEB above the GRS.  Surprisingly, it is not bright in methane band.   The NNTZ LRS and the South Polar red spot can both be seen on these images.

March 4, 2018 

Seeing was excellent when I start imaging.  Unfortunately, it quickly deteriorated after I took my first RGB set.  Clouds also made transparency variable!

Oval BA is well resolved and the red ring is distinct.   The STB Ghost is getting very close to Oval BA.   The SEB is still turbulent.  The NEB is quiet in this region.  The WSZ can be seen setting in this image.

March 2, 2018 

When I woke up this morning, the weather app of my phone indicated that the sky was cloudy with an Easterly wind.  When I got out there was some clouds but mostly clear.  Unfortunately, we had  N winds!   Seeing was variable and mostly mediocre.   Transparency was poor due to passing thin clouds.

The red Oval BA is well resolved.   The STB Ghost is very chaotic with knots of dark material and small white ovals embedded into it.  Note the small reddish oval to the left of Oval BA!

The SEB is  very turbulent whle the NEB looks quiet.

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!  

February 28, 2018 

I had a lucky break today.  The sky was mostly cloudy except for a patch around Jupiter.  Seeing was perfect!   After taking all the images I wanted to capture, the sky was overcast!

The dark SEB barge in prominent on these images.  The white and red ovals on the NEBn are well resolved.  The NNTZ LRS can be seen rising on the left.  This spot is bright in methane band.

February 27, 2018 

Seeing was good today.  I had to image late to catch Oval BA.

Oval BA is well resolved and the red ring is clearly visible.   The STB Ghost is now pushing towards BA.  The SEB looks quite turbulent in this region.

February 26, 2018 

We had horrible weather during the last few days due to a low pressure system that came over.  Seeing was good this morning though variable and transparency was a low due to thin clouds.

The GRS has a deep red color!   It is now interacting with the South Tropical Disturbance.   Note the bright band on the STrZ which is a circulation due to the interaction of the STrD and the GRS.  The South Polar red spot can also be seen.  There are some outbreaks and rifts showing up on the NEB. 

February 22, 2018 

Seeing was terrible today because of N winds.  It was also a bit gusty.

The GRS is setting on these images. It currently has a very strong red color!  The wake of the GRS is very turbulent.   Note the bright band forming on the STrZ which is bright in Methand band! The NEB looks quiet here.  Volcanic Io and it's shadow can also be seen.  The image of Io was taken from the first image I captured and pasted to the derotated image.

February 21, 2018 

The sky was clear this morning.  Seeing was good.  Unfortunately, dew was horrible!   I planned to use my dew shield but it sets my collimation off.  So I had to use Kleenex and wipe the corrector after each set..

The SEB dark barge is prominent on these images.  The NEB looks quiet in this region.

February 20, 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.

February 18, 2018 

Seeing was variable again today due to N winds.   The G and B data are still very bad.

These images show the remnant of the STB Outbreak.  The remnant is  mixture of dark barges and small ovals.   Oval BA is close to the terminator on the right.  

The SEB is active on it's northern half.  THE NEB is quiet in this region and has a very light color except on it's southern part.

February 16, 2018 

Condition was poor today.   Seeing was very unstable.

This is the region preceding the GRS.   Note the dark red barge on the SEB.  The NEB looks very light in color.  Europa can be seen on the NNTZ.

February 15, 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.

February 14, 2018 

We had a brush with Tropical Depression Sanba last Tuesday.  I wasn't sure I could image today. When I woke up at 4 am, the sky was overcast!  It cleared up by 5 am but there was still some clouds.   Seeing and Transparency was variable today.

The GRS and the STrD are now interacting!   The STrD is now turning the GRS halo yellow!   The wake of the GRS is very chaotic right now.  Note the methane bright feature rising on the left on the STrZ following the GRS!  The color image seems to show a bright feature surrounded by a brown arc.

The South Polar Red Spot can be seen just after the CM.  The NEB shows the alternating dark and white spots.

February 10, 2018 

Poor conditions today.  The NW winds are back and seeing was just so unstable.

The SEB shows the wake of the GRS.  Oval BA is rising on the left.  WSZ can be seen on the NEBn. 

February 9, 2018 

Condition was decent today.  

The GRS is rising on the left.   The STrD seem to be diving into the GRS halo.  The South Polar Red Spot can also be seen in these images.  Note the bright outbreak on the NEBs  embedded on the festoon just past the CM.  Will this create rifts on the NEB?

February 8, 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.

 

February 6, 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.

 

February 3, 2018 

Condition was variable this morning.  I had to wait for some fleeting period of good seeing to get these images.  

Oval BA is prominent in this image.  It's color is very pale but the reddish ring is resolved.  WSZ can also be seen.  It's northern region is no longer very bright in CH4.  The NEB and SEB are quiet in this region.

January 29, 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.

January 26, 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.

January 25, 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.

January 11, 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.  

January 7, 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.

 

January 6, 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?

January 3, 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.

December 30, 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.

December 28, 2017 

Condition was still poor today.  Seeing was unstable as Jupiter is still very low.

The GRS is prominent in these images.  It has a strong orange color.  The STrZ Disturbance can be seen rising on the left.The NEB is quiet in this region.

December 24, 2017 

Merry Christmas!  It's Christmas morning here and I woke up early for a date with Jupiter!  Seeing was poor today.

The South Tropical Disturbance can be seen setting on this image.   This feature is dark in Methane Band.  The NEB is quiet in this region.  White Spot Z can be seen rising on the left.  It still has a light orange color.

December 20, 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.

December 18, 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.
