It was partially cloudy this morning with a lot of haze.  Seeing was okay but not great. 

This is the area following the GRS.  The GRS can be seen setting on the 1st image.  Note the contrast of colors between the SEB and NEB.  The SEB is a little pale while the NEB is very dark. 

After imaging Jupiter, I was able to image an Volcanic Io occults of Icy Europa.  Seeing had already deteriorated during the eclipse.  These images were done with a  green filter.  Thanks to Larry Geary for the correction.

It was again hazy this morning.  Transparency was terrible when I started imaging but improved a little after around 15 minutes.  Seeing was excellent.

The GRS is very pale!  There are some features resolved inside the GRS but  the color is very striking.

There is a very complex rift system at the NEB.  Note the streaks on the NTB.  There are large ovals around the area of the NNTB.

May 27, 2009

It was partially cloudy this morning.  There was a thin haze in the sky so transparency was low.

Oval BA is rising.  It is very pale.  The SEB is very busy with a lot of mid-SEB activity.

The EZ is a bit turbulent.  The NEB has a complex rift.  It seems to have come from an interaction with the EZn.

There are still white band in this region north of the NTB.


May 25, 2009

Seeing was again good this morning.

Oval BA can be seen just past the CM.  The orange ring can still be seen but it is really very faint now.

The SEB has it's usual  dark  feature in the mid-SEB.

There is a complex rift system at the NEB.  The NTB is quiet at this region.  Note that the white NTZ is  not visible here.   Note the small red oval at the NNTB.

Another morning of excellent seeing!

The GRS is rising.  The GRS is now orange so should we change it's name to the Great Orange Spot? 8)   There is a hint of reddish haze on the STB.   Note the long dark bar on the SSTB next to the ovals.

The NEB is very busy.  The dark festoons of the EZn seems to be interacting with the NEB.  Note the outbreaks and rift systems on the NEB.

The NTB is also very busy now.  Note the feature which looks like the STrD on the NTBn close to the CM on the 20:58UT image.  Note the darker red coloring surrounding this feature.

There are a lot of small ovals at the NNTB. Note the small red oval.

May 22, 2009

Seeing was again excellent this morning! Transparency was variable but acceptable.

Oval BA is rising in these images.  It is really pale this year but there is still a hint of an orange ring.  The mid SEB looks very busy and there are hints of small ovals on  the SEB/STrZ border.

The NEB is very busy with a outbreak/rift at the CM.  There seems to be strong interaction between the NEBs and the EZn.  Note the dark red swirl below the outbreak.  There seems to be a red oval embedded in this swirl.

Note the dark band forming on the NTB.  There is also a small oval on the NTBn just before the CM.  The white band of the NNTZ seems to be breaking apart.


May 21, 2009

Seeing was excellent this morning!  It was a little hazy when I started imaging but conditions improved.

Lots of things going on in Jupiter.  Note that the STB is starting to turn red!  The GRS is pale.  Note the small red oval to the right of the GRS!  This this be consumed by the GRS?  The SEB is very busy in the area following the GRS.

There is a new outbreak in the NEB.  The NEB is really very busy this year.  Lots of outbreak white spots appearing!  The EZ also looks turbulent.

It is also  interesting to note that ovals are forming on the NTBn including a small red oval close to the CM on the 20:31UT image. Note also the huge white oval on the NTBn on the left!

There is also a huge white oval on the NNTB close to the CM on the 20:01UT image.

May 14, 2009

Seeing was excellent this morning!

The GRS is very pale.  Like Oval BA, it seems to be fading!  The area following the GRS in the SEB is very busy.  There are outbreak spots in the area close to the GRS.

Note the dark wide feature on the SSTB.

There are a lot of action in the NEB.  The NEB is very dark red.  There is a huge outbreak going on at the CM.

Note the dark spot and features on the northern edge of the NTB.

Io can be seeing moving away from Jupiter.

May 13, 2009

It was partially cloudy  this morning.  Seeing was average.

Oval BA can be seen on the left. It is still pale with a hint of orange.  The SEB is very busy with a lot of dark material uplifted by the outbreak.

Io's shadow is at the EZ.  Note the rift on the NEB.  The NEB is indeed busy this season.


April 15, 2009

Seeing was good this morning.  Jupiter was around 40 deg above the horizon.

Finally a good image of the GRS!  The area following the GRS is very busy. Note  the FFR on the  SSTB. 

Note the bright area on the NEBs just before the CM.  Will this bright area turn into an outbreak?  Note the dark red spot on the NEBn just  below the GRS. Note the disturbance like feature on this.  This looks like the STrD.  Note also the white spot on the NEB just rising on the right.  The NEB seems to be active this season!

April 11, 2009

Happy Easter everyone!  I finally got good conditions today!   Jupiter was around 40deg above the horizon when I took these images.

Note the outbreaks on the SEB and NEB!  The mid-SEB outbreak seem to be associated with the dark feature on the  mid-SEB.  While  the NEB outbreak is associated with a rift system. 

The STB looks a bit busy.   Note the dark area surrounding the SSTB white spot close to the CM.

The NTB looks faint in this area.  Note the irregular white band north of the NTB.


April 9, 2009

Jupiter is still below 40 degrees above the horizon. Seeing was okay for the altitude.

Oval BA is getting close to the CM in this image.  It still has an orange color so it hasn't really reverted back to white.

The SEBs is very dark.  While the mid-SEB looks very busy.   There is a large dark festoon on the EZ.

The NEB is very dark.  Note the  rift on the left.  The area north of the NTB has a lot of dark features.


April 8, 2009

Seeing was excellent this morning.  Considering Jupiter is only 35deg above the horizon when I took these images, these are pretty good. 

A huge Folded Filamentary Region (FFR) can be seen on the SSTB just after the CM.  This is the sausage shape feature between the two white ovals. 

The GRS can be seen on the left setting.  The mid SEB is quite busy with outbreak wakes visible.  The EZ looks quiet.

The NEBn has a lot of activity.  Note the two huge white ovals close to the CM.  Note also the large red dark oval setting on the left.  The NNTB Little Red Spot (LRS) can be seen faintly in the image below.



April 7, 2009

Seeing was better this morning. 

Oval BA is setting on the left.  It looks white now compared to its reddish color in the past 3 years. 

The SEBs looks dark red while the mid SEB looks busy with a lot of dark features.  Note the prominent oval at the SSTB on the CM.

The NEB is very dark red.  Note the large White Oval Z at the NEBn at the CM.  This oval seems to be growing.  There are a lot of dark features at the NEBn.  The EZ has some prominent dark features.


April 2, 2009

Seeing was poor this morning.  I did not have time to cool my OTA. 

Oval BA is visible close to the CM.  It is rather pale and with only a hint of redness.  There is a rift in the NEB on the left side.  There are also some interesting dark features north of the NTB at the CM.


March 27, 2009

Seeing was a little better this evening.

There some interesting activity  in Jupiter.  The GRS is setting in this image.  The area following the GRS is filled with outbreak activity.  There is an FFR at the SSTB in between two white oval.

The EZ looks quiet.  But there is a big cyclonic red spot on the NEB setting on the left.  There is also a two large white anti-cyclonic oval at the NEBn!!  Looking at the Jupiter as a whole, the northern hemisphere looks red while the southern hemisphere looks pale.

March 26, 2009

Jupiter is still very low in the sky.   Hopefully images will get better as Jupiter gets higher in the sky.

Nothing  really interesting going on in Jupiter.  Oval BA is setting on the left.  The SEB and NEB are quiet.  Note the oval at the SSTB.   The NTB is prominent now and  seems to have fully revived.  Note the dark features on the NTBn.  There seems to be some festoon activity on the EZ.


March 21, 2009

Condition still not good.  Jupiter is still very low in the sky only around 20 degrees above the horizon.

Oval BA is very pale in this image.  Oval BA is still bright in Methane band.  The south pole is  brighter in Methane band than the north pole. The NEB is very dark red.  The SEB seems tohave the same color but with a mid-SEB activity.  There are some dark features north of the NTB. 

March 17, 2009

I have an early start this year.  Jupiter was only around 20 degrees above the horizon when I imaged this morning. Seeing was good for this altitude.

Jupiter seems to have quieted down.  Oval BA is visible on the left.  The ring can still be seen in the blue channel so it is technically still red.  But it's color is a paler than last year.  Will it turn white this year?  Who knows...

The SEB and the NEB has the same dark red color.  The mid-SEB section is very busy.  The EZ looks quiet with little festoon activity.  The NEB is also devoid of activity.  It is just dark red.  The NTB is distinct.  The polar regions are dark.
