Happy New Year!  It's 2016 here in the Philippines.  I woke up early today to capture some Jupiter.  Seeing was variable but I had a period of excellent seeing towards the end of my imaging session.  Seeing was very variable because of clouds.  It was also very windy this morning!

Oval BA can be seen in these images.     Io can be seen on the NEB.   The NEB is wide in this region. 

December 30, 2015 

Seeing was good today. 

The blue STB ghost can be seen rising on the left.  Note the features on the SEBn. 

There is a bright outbreak on the NEB and complex rifts on the NEB. The NEB is narrow in this region.  A lot of activity on the NTB/NTZ in this region.

December 29, 2015 

Seeing was variable today.  It was also a bit windy today.  But there were periods of good seeing.

Oval BA can be seen close to the CM in the first image.   It's color is a bit pale when compared to the GRS.  The STB is very clear this season.

Note the dark red spot on the SEB.  The NEB has a lot of rift activity in this region.  Note the three dark spots on the NEBn. 

December 26, 2015 

Condition was  poor and windy. 

The GRS can be seen with a very strong color.  The "wake" of the GRS is very chaotic. 

The NEB looks very active in this region.  The White Spot Z can be seen rising.  The area around WSZ is wide while the preceding area is still narrow.

December 25, 2015 

Merry Christmas!  It's been more than a week since my last image.  Weather has been very bad during the last week.  Seeing was good today.

The NEB is very active in this region.  Note the bright outbreak and the complex rift .  The NTB looks interesting with more than a dozen small white ovals this this belt.  

The SEBn looks interesting with it's light color.  The STB looks blank except for the blue STB ghost.

December 15, 2015 

We had a close call with a very powerful typhoon.  Fortunately, we did not experience any strong winds. Seeing was very unstable this morning.

Io's shadow can be seen on the NEB.  The SEB is quiet in this region.  Note the dark red barge on the SEBs.  Is this the remnant of the merged red spots.  The NEB has a lot of rifts.

December 12, 2015 

Condition was horrible today.  Seeing was very unstable because of an incoming typhoon!  I had to reject a lot of images around 70% of my data.  I also had to do some hard sharpening to get these images.

Oval BA can be seen rising on the right.  It's light orange color is distinct.  The SEB looks quiet in this region.  There are rifts on the NEB and it is wide in this region.

December 11, 2015 

Seeing was variable today but transparency was perfect.  Now dew problem today.

The GRS is rising.   The STB ghost can be seen just past the CM.  This feature is very dark in CH4!  Note the chaotic NEB.  The NTB is active in this region.  Note the multiple small white spot and the dark red northern edge.

December 9, 2015 

Condition was very challenging this morning due to dew.  When imaging the methane band, transparency was only 50%!

The GRS is very resolved in these images.  The dark red core.  The black thin outer ring can be seen.  There are currently two outbreaks following the GRS generating its complex wake.    Due south of the GRS, one can a SSTB white anti-cyclonic oval interacting with a cyclone.

The White Spot Z can be seen on the NEBn.  The area preceding the WSZ is narrow while the area following is wide!  Note the dark red material surrounding WSZ and the black feature inside WSZ.    The area preceding the WSZ looks very active.  Are new anticylones being formed?

December 7, 2015 

Condition was poor this evening.  Seeing was terrible and transparency was poor.  I had to reject 80% of my data this evening! 

Ganymede can be seen on the upper right.  Some features can be resolved.  The SEB is active on it's southern edge.  The NEB is wide in this region.  The White Spot Z is setting on the right. 

December 5, 2015 

Transparency was poor today because of thin haze but seeing was good.

Oval BA is well positioned this evening.  The reddish ring is well resolved.   Note the small oval above the "wake" of Oval BA!  Will this get swallowed by Oval BA?  Oval BA is very bright in methane band.

The dark red streak on the STB is still prominent.  This was the remnant of the  merger between two small dark red oval.

There are two prominent outbreaks on the NEB.  A lot of complex rift activity on the NEB.

 

December 4, 2015 

Condition was challenging today .  I had to image during a break in the clouds.  I was fortunate to get a set of RGB.  However, I did not have time to capture a Methane band image before clouds rolled in.  Seeing and transparency was variable.

The GRS has a very strong color.  The dark core is well resolved.  The wake of the GRS is very chaotic while the region following the GRS looks calm.   

Note the outbreak on the NEB.  This region of the NEB is narrow.

December 3, 2015 

Seeing was average this morning.  Transparency was poor and I had to cut my imaging session because of clouds.

Note dark red streak on the SEB just past the CM.  This of the remnant of the two small dark red oval that merged earlier this week.  Oval BA is setting on the right.

There are a lot of complex rifts on the NEB.

 

November 30, 2015 

Seeing was excellent this morning but transparency was poor.

Finally caught Oval BA!    The reddish ring is still visible but is very thin now.  This is in stark contrast with the strong color of the GRS! 

The SEB is quiet in this region.   Note the two small red ovals I had predicted last week has MERGED!    THis is the dark red spot rising on the left!  Seems like merger is still ongoing!

The NEB is wide in this region.  Note the outbreak and rifts on the NEB!

November 29, 2015 

Woke up 4am today to find the sky overcast.  Went back to bed.   Woke up 5am and the sky cleared!  Today is a holiday here so I went ahead and took some image.  Seeing was good but transparency was deteriorating because of dew.   I wasn't able to take the methane band because of dew and sunrise!

The GRS has a very strong color.  The dark color can be seen.   The halo has a yellow color.  The region following the GRS has outbreaks creating the wake. 

There is a bright outbreak on the NEB creating complex rifts.

 

November 26, 2015 

Condition was perfect today.

The NEB is very active but at this region it is narrow compared to the region yesterday.  The SEB is active in it's northern edge.  Note the two dark red spot on the SEBs setting on the right.  Will these two spots merge?

November 25, 2015 

Seeing was very variable this morning.   This is probably due to gust.

The Southern Polar red spot can be seen just past the CM.  This spot is still bright in CH4 but barely!  Note the dark red barge in the STB.  The SEBs shows the wake of the GRS.  The NEB is quiet in this region.  Note the White Spot Z setting on the right.  The NEB is very wide this year!  Note that the reddish material is at the level of the WSZ!

November 24, 2015 

Seeing was excellent this evening although transparency was variable.

Finally caught my first image of the GRS this season although it is just peeking out at the edge.  The color of the GRS is very strong!  The SEB looks quiet in this region while the NEB is very chaotic.   The STB ghost can be seen and it is a dark streak in Methane band!  There are dark barges on the NEB in Methane band!

November 14, 2015 

Condition was excellent this evening. 

The NEB is very active.  There are outbreaks on the NEBs/EZn close to the festoons.  Notice the reddish ring on the NEBn.  The SEBs continues is also active and note the wavy pattern on the STrZ/SEBs region.  Nothing remarkable on the CH4 image except for the bright outbreak spots on the NEBs.

November 13, 2015 

Condition was better this evening.   Seeing was average but transparency was variable.

The dark moon Callisto can be seen on the lower left of Jupiter. Note the bright pole is visible.  White Spot Z can be see on the NEB.  This spot is back to white in color but the surrounding region of this spot is very active.   Note the white elongated feature on the NTB before the CM.

The wake of the GRS is prominent on the SEBs.  The south polar red spot is prominent.

November 12, 2015 

I had a challenging imaging run today.  The sky was clear when I started woke up. But as soon as I started my imaging run, the sky became overcast!  I was able on make only 1 RGB run but with very poor transparency!

The GRS is rising on this image.  The SEBn looks active while the NEB seem to have complex rift activity.
