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.

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.

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. 

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.

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.

 

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.

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.

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.

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.

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.

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.

 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.

 

 

 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.

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.

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. 

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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. 

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.

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.

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.

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.

Conditions were very poor today. 

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

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.

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.

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.

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.

 

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. 

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.
