JUPITER: July 2008

By Christopher Go


July 29, 2008

Condition was  poor.    Transparency was okay but seeing was horrible because of the southwest monsoon. 

The GRS and Oval BA can be seen transiting the Jovian disk.  Oval BA looks pale orange.  Both spots are very bright in the Methane Band filter.  The SEB has become dark red.

 Note the NEB rift on the images taken before 13:00UT. 


July 27, 2008

Condition was very poor today.    Transparency was very poor because of clouds. 

The GRS is setting in this image.  The STrZ white oval is closing in on the GRS!  Will this follow the little red oval?   The area right of the GRS is very busy.

Io can be seen on the NEB.  The NEB is very dark red.


July 23, 2008

Finally a clear night!  Seeing wasn't great though. 

The SEB is very busy. Note the red spot at the SEB.  Note that one of the SSTB white is bright in Methane band.  Note also the dark band at the STB.

Note the large dark spots at the NEBn!  There is also a large white spot at the NTrZ.

July 21, 2008

It was mostly cloudy today.  Seeing was good but transparency was horrible!  Weather had been horrible during the past week.

The SEB outbreak is prominent.  Note the red spots on the mid-SEB.   The NEB is very dark.  Note the large white spot to the right of Europa's shadow.  Note the dark feature at the NNTZ southern edge.


July 15, 2008

It was again cloudy this evening.  Again there was a short break for one color image.

The GRS can be seen just passing the CM.  Oval BA has passed the GRS.  No sign of the LRS here.

The NEB is still dark red with some signs of rift activity at the CM.


July 14, 2008

It was very cloudy this evening.  There was a break in the cloud but only enough for a red image of Jupiter. 

The SEB is very busy because of the SEB outbreak.   Ganymede is on the right.


July 12, 2008

Condition was very poor this evening. It was mostly cloudy and I had to image Jupiter through clouds! Transparency was very poor and so was seeing.

The GRS and BA are close to the CM.  Note the bright long feature emanating from the northern edge of the GRS through the SEB.  No sign of the LRS in this image.


July 10, 2008

I  had to start imaging early today to catch the area around the GRS. 

In the methane band image below, the high altitude cloud of the STrZ LRS has  dissipated!  The remnant can be seen east of the GRS!  In visible light, the LRS can no longer be seen!  The SEB area following the GRS is very busy!

The STB white oval surrounded by a dark ring looks interesting.  Oval BA's red ring is very prominent.  It has now passed the GRS.

Note the rift forming on the NEBs rising on the right.



July 9, 2008

Condition was not good during the start of my session but improved as Jupiter went higher in the sky.

Note the South Equatorial Disturbance (SED) is very prominent in this image.  It looks yellowish at  the  SEBn close to the CM at the image below.  Note the connection of the SED and the mid-SEB white spot.  The SEB is very busy from the outbreak.  Note the dark red spot on the mid-SEB.

The NEB is very dark red.  It looks quiet except for the Disturbance like feature at the NEBn.

July 7, 2008

Condition was okay this morning.  I was finally able to use the Methane Band Filter Imke de Pater sent to me!  Thanks Imke!

Finally, a good image on the 3 red spots.  It seems that the LRS might have survived it's passage between the GRS and BA!!  You can see it attached to the p side of the GRS!  Note it's red material spread all over!  In the Methane band image the LRS is distinct.  It seems like this spot will be attached to the GRS and probably get absorbed as it goes around the GRS.

Note also that the NNTZ LRS is bright in methane band!  The red ring of BA is still very distinct.

The SEB is very busy.  Note the dark barge at the SSTB.  The NEB is quiet.

July 5, 2008

Seeing and transparency was horrible.  There was a light shower during the start of the session.  I was having second thoughts whether I should image or not.  I was only able to get 1 image before clouds rolled in!

The Oval BA is now in conjunction with the GRS.  The LRS just went between the GRS and Oval BA.  Note the reddish protrusion southeast of the GRS!  Is the the LRS remnant?


July 1, 2008

Seeing was not very good today and transparency was poor.

Note the SEB is very pale. Note the wake feature at the SEBn.

The NEB is really very red.  The SEB seems to be fading.  WSZ can be seen on the right.
