December 31, 2013

Happy New Year!!  This is my last image of the year.  As I type this it's just 2014 here in Cebu City.  It's amazing how seeing changes in a few minutes.  In my RGB image on the left, there is a huge difference in image quality even though they were taken less than 10 minutes apart.  I had to image early before Cebu turns into a warzone with crazy fireworks.

The GRS is setting on the right.  Note the complex wake following the GRS and the numerous outbreaks erupting in the wake.  These outbreaks are bright in CH4.  In  the SSTB, note the "Mickey Mouse" like feature that is formed by the two AWO and the large cyclonic spot between the AWO.

The NEB has a lot of rift activity.  White the NTB is quiet in this region.  A lot of spots can be resolved in the northern temperate region.

 

December 28, 2013

Seeing was a bit variable today.  Jupiter was still low when I took these images.  I just had to catch the ROZ.

The area preceding the GRS has a lot of activity!  Jupiter's new red spot  what once was White Spot Z still has a reddish color but still a bit faint.  The spot looks very bright in Methane band.  The NTBn is still very chaotic.  Note the prominent red feature just south of the NNTZ LRS.

December 26, 2013

Merry Christmas!  Seeing was good this evening even though I imaged Jupiter when it was still low in the sky.

The Great Red Spot is the main feature in these images.   The halo of the GRS has a yellowish color.  Note the bright outbreak just west of the GRS!  The wake of the GRS is very complex.   Note the large SSTB spots rising on the lower left.

The EZ/NEB still has very complex interactions.  The festoons are pushing into the NEBs with a lot of complex cloud features.  The NTB has some activity in this region. 

December 21, 2013

Seeing was a bit variable this evening but I was able to catch some good moments.

The GRS is well resolved and the region around it is very complex.  There is a curious bright feature to the Southwest of the GRS.  This feature is bright in methane band.  Note the complex wake and the yellowish region on the halo of the GRS.  Note red features that seem to be emanating from the GRS lining up on the STrZ. 

The new red spot ROZ can be seen setting on this image.

The NEB is very dark.  The NTBn looks active.

December 20, 2013

This imaging session was a bit frustrating because of clouds.  Seeing was okay but transparency was variable.  I had to image between clouds.

Jupiter's new red oval is now getting more prominent.  What was White Oval Z now has a more prominent red color.   It is even getting darker through the green filter!  This spot is also very bright in Methane band much brighter than the NNTZ LRS.

The NNTZ LRS has a strong red color.   Note the dark red barge to it's southeast.   The NTB is very chaotic.  There are three spots in the NTB!  A white cyclonic spot and a dark (black) spot with a large  Anticyclonic White Oval between these spots.  The region following these three spots show a disturbance similar to the wake of the GRS!

 

December 19, 2013

Condition was terrible this morning.  Seeing was unstable.

Oval BA can be seen setting on  this image.  The SEB looks complex.  Note the dark spot on the SEB.  Note the little red spot on the NTZ and the complex feature just north of it.

December 17, 2013

Woke up later than my planned imaging.  I was having second thoughts on imaging but went ahead to image anyway.  Seeing was average.

Jupiter's possible new red spot, what was White Spot Z or Red Oval Z now can be seen rising on the left.  The red color of this spot is getting stronger.  The NNTZ LRS can be seen to it's northeast while the GRS is rising.  The NEB is very complex with a lot of festoon interaction activity.  Note the chaotic NTB and the white ovals on the NTB.

December 11, 2013

Seeing and transparency was very variable today.  Jupiter was still low when I took this image.  Had to catch the GRS and ROZ.

The GRS is very well resolved.  Note Europa on the left edge of the GRS.   Europa's shadow is preceding the GRS on the right.  The SEB looks very busy especially at the wake of the GRS.  There is an interesting reddish cyclonic feature on the SSTB between the white ovals.

The Red Oval Z is now more distinct.  Color is still light. The NEB is very dark and very busy with a lot of rift activity.  The NNTB LRS can be seen setting on these images.

December 9, 2013

Transparency was very poor this morning because of haze.  Seeing was however excellent.

Oval BA can be seen rising on this image.  The SSTB white ovals are prominent.  Note the dark center on each of these ovals!  Also, note the cyclonic spot between the two white ovals close to the CM.  This cyclonic spot looks light in methane band!  Note the dark features lining up on the STBn towards Oval BA.  There is a white spot close to the SPR.

The wake of the GRS can be seen on the SEB.  Note the dark features lining up on the STBn towards Oval BA.  The NEB is narrow but dark red in color.  Note the STZ red spot and the dark features to it's north.

 

December 7, 2013

I tried imaging earlier this morning. It was cloudy.  The sky cleared 2 hours later.  Seeing was ok but deteriorated as Jupiter got lower.

The SEB looks complex.  This is the area preceding the GRS.  Note the little red spot on the STrZ.  The NEB is very busy with the EZ festoons creating rifts on the NEB.  Note the large cyclonic red spot imbedded on the NEBn.   The NTBn looks very busy. 

December 4, 2013

Seeing was unstable today.  But improved a little bit towards the end of my imaging run.

The SEB shows the complex wake of the GRS.  There are dark red features lining up on the STrZ.

The red Oval BA can be seen rising on the left.  Note the SSTB white ovals.  The NEB has a strong color but it is currently narrow.  Note the complex EZ including an area that is bright in methane band.

 

December 3, 2013

I overslept this morning.  Jupiter was past the zenith!  Seeing was good this morning.

The GRS is very distinct.  Details can be seen inside the GRS.  The area around the GRS is very busy.  Note the dark coloring of the STrZ preceding the GRS.    Note the white feature north of the GRS.  The SEB  is very complex.

The new Red Oval Z (ROZ) is now very distinct.  The red color is not more prominent and a dark edge is now forming.  ROZ is bright in CH4 and dark in UV.  The NEB is dark and narrow. 

The NNTZ LRS can be seen setting on this image.

 

 

November 30, 2013

Seeing was great this morning.  Unfortunately, the imaging session was  cut short because clouds rolled in. So no methane and UV band images. Transparency was variable when I took the IR image as Jupiter came on and off the clouds.

The red Oval BA is prominent in this image with it's own complex wake!  The color is very strong this year and the white core is still visible.

The SEB is very complex.  Note the dark red cyclone on the SEBs.  The NEB is active but narrow.  The NTB has a distinct color with an active northern part. Note the two small red spots on the NTZ.

 

November 26, 2013

Seeing was excellent again this morning. 

3 big red spots visible in this image.  The three reds spots are bright in the Methane band image but dark in the UV image. The GRS is very prominent. and well resolved.  A lot of details can be seen inside the GRS.  The NNTZ LRS can also be seen.  It is fully red now with a dark ring on it's edge.

The NEW red spot is what once was White Oval  Z.  Last February this white oval had a merger with another NEBn white oval.  Interestingly, it became very bright in Methane band starting this season!  Now it has a reddish haze.  Will this turn very red like the NEB red ovals in the 1970s?  Or will this reddening be temporary?   (Thanks Agustin!)  So please keep monitoring this spot.

Note that the STrZ preceding the GRS has a reddish tinge as noted by Damian Peach.  The SEB is very complex.  Note the outbreak following the GRS.  The NEB also looks very busy with a lot of EZ festoons intereacting with the  NEB.

November 25, 2013

Another morning of excellent seeing! 

Jupiter looks like it has a measles attack!  Red spots galore.  On the south, the Red Oval BA can be seen.  On the NTZ, you have two small red ovals.

The SEB looks very complex.  Note the dark red cyclonic ovals lining up on the SEBn.   The NEB is narrow but very complex.  There are a lot of outbreaks on the NEB.  The NEB is faint but active on it's northern half.

November 24, 2013

Seeing is excellent this morning!  I was able to clean my camera and the images a better now.

The GRS is prominent in this image.  Note details inside the GRS.  It has a dark red core and some vortex features.  The wake of the GRS is very complex.  Note the bluish feature on the STB south of the GRS.

The NEB is narrow and a lot of rift activity.  Note the White Oval Z (WOZ) on the NEBn setting on this image.  It looks like it has turned reddish.  Checking past images, there seems to be some darkening in Tomio Akutsu's image on Nov 14.  The UV image shows a very dark spot on the position of the WOZ.

Note the complex feature on the NTB. 

November 17, 2013

It's been quite sometime since my last image.  Our country went through quite a lot of events.  We had a 7.2 mag earthquake plus a Jupiter type Super Typhoon (with max winds of 370kph!).  Fortunately, we are ok here. 

Seeing was excellent this evening.  But my images have some vertical artifacts which was the result of not cleaning my camera properly. 

Oval BA is rising on this image.  Note the complex SEB.  The NEB is narrow and has a lot of rift activity.  The NTB has a light red color with some activity in the dark band on it's northern part.  Note the dark red feature on the NNTB.  I'm just wondering what is the methane bright feature on the Equatorial zone?

September 13, 2013

Seeing was unstable today. 

Europa is on the SEBs.  It is very bright in CH4.  The SEB looks quiet in this region.   The STB streak is prominent.  THe NEB is narrow.  The NTB has a dark streak on it's northern edge. 

September 7, 2013

Condition wasn't great this morning.  Seeing was excellent but transparency was poor.  Plus I had to deal with dew.  However, I was able to scrape a decent RGB image.

The GRS can be seen rising on the left. Note the bright patch on the SEB preceding the GRS.  Is this a vortex?  IT seems to be associated to the dark wake on the SEBn.

The NEB looks quiet and narrow. 

September 3, 2013

Seeing was excellent this morning!

Note the interesting CH4 band bright spot on the NEBn!  At first I though this was the NEBn dark spot but it seems this bright spot corresponds to a  white spot on the NEBn White Spot Z!! Note the bright arc on this area which indicates the edge of WSZ!

Note the small red spot on the NNTB. 

The SEB is very complex with the wake of the GRS. There is a bright outbreak at the wake of the GRS.  Note the bluish feature on the NTB is very dark on the CH4 band!

September 1, 2013

Seeing was a bit unstable today. 

The SEB is very busy in this region.  The NEB looks narrowing but has a strong red color.  The NTB has a light red color.  Note the feature on the NTBn above the dark band just past the CM.

August 31, 2013

I had a late start with Jupiter this season.  This was because of the active monsoon season here in Cebu.  Seeing was excellent today! These are my first images of Jupiter with the ASII20MM.  The sensitivity of the camera is astounding.  It blows away the ICX618 chip and I was surprised with the good results in the Methane band.  I can now really say that the ICX618 is dead.  LONG LIVE CMOS!! There might be some artifacts in my images due to dust in my camera.

The GRS is prominent in these images.  The GRS is well resolved with details inside the GRS!  The wake of the GRS is very complex while there is a bright area preceding the GRS.

THE NEB looks narrow!  Note the dark red spot on the NEBn.  This spot is bright in Methane band.  The NNTZ LRS  can be seen up north and there is a small red spot just south west of the NNTZ LRS!  This small red spot is bright in Methane band.
