NOVEMBER - DECEMBER 2011

December 29, 2011

It was mostly cloudy this evening.  I had a good break in the clouds that enabled me to take for images of Jupiter.  Seeing was very variable but with the derotation tool, a bad day can still be salvaged!  I was able to scrape 4 RGB sequences before clouds rolled in.

The GRS wake is very active and complex.  Note the outbreak spots following the GRS.  The NEB is very narrow and the dark red barges are very impressive!  The northern hemisphere is very quiet.

Merry Christmas!  This is my first image after Christmas.  Seeing was very variable.  I used the de-rotation tool to improve the images.

The NNTZ LRS is bright in Methane Band.   In visible light, it's a white spot.  The NEB is very narrow while the dark NEBn barge is very prominent.

The SEB is still very active.  The  north and southern edge of the SEB are still dark and very active.   Note the bright feature on the SEB.  Is this the SED?

Seeing was very unstable this evening.  Fortunately, the high speed of the Flea3 and the new Registax Derotation tool really help in  making these image look good!

The GRS is rising on these images.  The SEB is very dark with complex activity on it's northern and southern edges.  The NEB is very narrow and the dark oval on the NEB is very huge!

Seeing was still very unstable this evening.  But it improved as Jupiter got higher.

Here's an image of Jupiter with the GRS.  The action of the SEB is in the area around the GRS.  Details inside the GRS are well resolved.  The wake of the GRS is very complex.  While the halo of the GRS is dark.

The NEB is very narrow in this region.  I used Winjupos derotation on all the images.

December 18, 2011

We had a brush with Tropical Storm Washi.  Everything is okay in my area but the southern Philippines was devastated by this storm.  Seeing was unstable this evening.  Transparency was also not very good.  I did not use any winjupos derotation on these images because the moons seem to mess things up.

The SEB is dark in this region while the NEB here is wider but still narrower than normal.  Io and its shadow is on the SEB.

It was mostly cloudy today.  But the sky cleared.  Transparency, however, remained poor.  Seeing was very good.

The images today are similar to the images I took two days ago.  The GRS is the highlight.   One can see the changes on the wake of the GRS!   The SEB continues to be complex due to the interaction of the GRS and the outbreak following it.

The NEB is very narrow!

Made some changes in processing. The image on the right uses Winjupos derotation using 3  images.  Click the image on the right to see the  comparison.

The pain of the appendectomy is slowly subsiding.  It still hurts when I exert myself but is slowly becoming bearable. Seeing was a little rough this evening.  But it was compensated by the sheer speed and sensitivity of the Flea3!!

The GRS is setting and there is a full view of the wake that follows it.  Outbreaks are very prominent in the area following the GRS.  The GRS is still surrounded by a dark halo. 

The NEB is really very narrow now!!  

December 10, 2011

I just had an emergency appendectomy on Dec 7.   I'm back now, but my tummy still hurts a bit.  I would like to thank my surgeon Dr Henry Chua for the wonderful job! I was able to take some Jupiter images before the total Lunar Eclipse. Condition during imaging Jupiter was less than perfect.  Seeing was good but transparency was poor and variable.

Oval BA can be seen in this image.  The red ring is very prominent!   The dark halo is disappearing.   Note the white spot following BA.    The dark shadow in the right is Europa's shadow.

The SEB is still very complex.  The NEB is very narrow.

An hour after taking these images, a Total Lunar eclipse started.  I used my old C8 and my Nikon D5000 to take this image.

December 2, 2011

Condition was almost perfect this evening except for some clouds.  These are some of my  best images of Jupiter with the GRS.

The GRS is well resolved in these images.  The dark halo around the GRS is also covering the STrZn.  The outbreak area is now just next to the  GRS.  This is the reason why the  SEB is very active this year. 

The NEB is narrowing making the dark ovals prominent.  There is now a  hemispheric reversal in color for Jupiter.  For the past few years, the southern hemisphere was pale while the dark north was reddish.  Now it is reverse.

It rained early this evening.  The sky cleared up close to 9pm local time but transparency was poor.  Fortunately seeing was good.

Oval BA can be see in this image.  The red ring can still be seen but contrast with the surrounding area is poor.  The halo around BA is dark like the GRS.  The SEB is still very disturbed with dark north and south edges.  The NEB is very narrow now.  The northern temperate area is quiet in this region.

 

November 29, 2011

The evening started with cloud cover with most of the sky.  Fortunately it cleared up.  Seeing was excellent!

The first thing that caught my eye is the two ovals on the NNTZ that are starting to merge!!  This needs to be monitored as these two ovals should complete the merger in the coming days.  The dark bar in the NNTB is striking.

The NEB is calm with the large dark oval on the NEBn.  The SEB is still very disturbed.  The GRS is surrounded by a dark halo.

November 28, 2011

Everything was perfect this evening.  The sky was clear and seeing was excellent!

Oval BA can be seen in the CM of the first image.  The red ring is still visible but the background is hazy.  The STrZ is dark with the northern part very disturbed from the wake of the  interaction of the GRS.  There is a white oval close to BA.  Will this merge with BA? 

The SEB is still very busy.  The NEB is quiet.  The dark spots on the NEBn are very prominent.  Note the red spot on the NTB which looks like an "eye".

November 27, 2011

Imaging was tough this evening.  It was again mostly cloudy with some breaks in the clouds.  Transparency was very variable.

The GRS can be seen here on the CM of the second image.  The area around the GRS is very disturbed.  Outbreaks can be seen in the area following the GRS.  These outbreaks create the turbulence around the GRS.  Note the dark halo around the GRS.  Features can be seen inside the  gRS.

The NEB looks quiet.  The dark ovals on the NEBn are very prominent.

 

November 26, 2011

Condition was crazy this evening.  It was raining about  15 minutes before I was imaging.  I thought that this evening was hopeless.  But when I went out, the sky was suddenly clear!  Seeing and transparency was excellent!

The NNTZ LRS is prominent in the Methane Band.  But is absent in the visible light.  There is a hint of an oval but it is difficult to see.

The NEB is quiet and narrow.  Note the small dark spot on the NEBn.  The SEB is busy.  Note the wide dark band south of the SEB!

November 25, 2011

It has been almost 2 months since my last image.  I travelling to the USA last October.  When I came back home, my filter wheel broke down!  Fortunately, I was able to get a replacement from Charlie Hein!!  Thanks Charlie!!

Conditions was great this evening.  I just finished assembling the new filter wheel to my imaging system.  It was mostly cloudy but I had to test out my new system.  Transparency was variable but I was able to scrape one decent image.

The SEB looks very busy.  This is because of the outbreak close to the GRS.  Oval BA is rising on the left  Note the dark barges on the NEBn.
