Seeing was terrible this morning because of  the effects of Typhoon Nalgae.  I was able to scape one image.

The SEB and NEB are very quiet.  The SEB seems to be losing color.  The NEB is narrow.  The STrZ has a reddish haze.

Io is to the right of Jupiter.

September 30, 2011

We had cloudy skies because of Typhoon Nesat.  Seeing was still unstable because of the southwest monsoon.

Ganymede can be seen  above Jupiter.   Note the bright spot on the Methane Band.  This is the NNTZ LRS.  Curiously, it is difficult to make out this spot in visible light!  The red ring has disappeared!

The SEB seem to be losing color!  With the absence of outbreaks will the SEB fade again as John Rogers predicted?  Note the red spot on the mid-SEB just before the CM.  The STrZ is hazy.

The NEB looks quiet.  The dark red spots are still prominent.

September 21, 2011

Transparency was poor this morning because of clouds.  Seeing was also very unstable.

The  SEB is very broad while the NEB has narrowed.  White Oval Z can be seen on the NEBn.

 

September 20, 2011

Woke up early this morning.  But there was a cloud around the area where Jupiter was.  I went back to bed and it took 90 minutes for the sky to clear up!   Unfortunately, Jupiter was past the Zenith and I was able to get one good image before conditions deteriorated.

 I was able to test out my new laptop.  It is a Thinkpad T520 and it  has a dual core Intel Sandy Bridge CPU!  Firecapture runs flawlessly with this baby!  I have also retired my JMI NGF-S focuser.  From now on, I will be using a motorized Moonlite Focuser!

The SEB is broad and dark.  There are no outbreaks here.   Note that the SEB is looks very active!  The NEB is narrow but dark.  Note the dark ovals on the NEBn! 

Oval BA is rising and can be seen in the Methane Band image.

September 15, 2011

It was mostly cloudy today and condition was unstable.

Here's an interesting image, Io is over the GRS!!  The SEB is dark. 

September 14, 2011

Seeing was again excellent this morning!

This is the area opposite to what I imaged last night.

The STrZ isn't pure white.  It has a yellowish hue.  The SEB is still very busy activity all over.  Note the small dark ovals lining up on the mid-SEB.

The NEB is narrow.   The NNTZ LRS can be seen rising in the last image.  It has noticeably lost its color.

 

September 13, 2011

Seeing was excellent this morning!

There are a  lot of details in Jupiter.  The STrZ is still dark.  The SEB looks pretty mixed up.  There are dark ovals on the SEBs.

The NEB is narrow but the dark ovals on the NEB are very distinct.

August 31, 2011

Seeing was terrible during the start of my session.  But it improved after a few minutes.

The GRS in very prominent in this image.  The dark halo wraps around the GRS extending to the STrZn.  The STrZ around the GRS is reddish. There is a new bright outbreak spot following the GRS.

The huge dark NEB oval is still very prominent.  It seems to be interacting with an outbreak just south of this object. 

August 30, 2011

Seeing was a little unstable this morning.  Fortunately I was able to get some decent images.

Oval BA is setting in these images.  It still has a light orange color.  The shadow in the right is Io's shadow.  Io can be seen at the SEB.  Note the dark red features on the mid-SEB.

The White Spot Z is very prominent on the NEBn.  It looks a little bright in Methane Band! 

August 29, 2011

It was frustrating this morning!  When I woke up, the sky was clear,  After setting up my system, the sky was overcast!  Since today was a holiday, I just waited out the clouds.  I was able to image in between clouds.  The sky finally cleared after 30 min.  Seeing was variable but with periods of good seeing.   In the end, the frustration was worth it!

The GRS is prominent in this image.   Note the dark halo around the GRS. The GRS is pale.  Note the faint dark ring inside the GRS.  The SEB is very turbulent.

The NEB is starting to get busy.  Note the huge dark oval on the NEB.  This oval has really grown huge. 

It is interesting to note that in the Methane band, the NTB is dark.  But it is light in visible light.

August 27, 2011

I overslept this morning.  When I started imaging, Jupiter was past the meridian!  Seeing was very good when I started imaging but deteriorated after a few minutes. 

Oval BA can been seen rising in this image.  I can make out the red ring inside but the contrast is very low.  The SEB looks very complex.

The NEB is quiet.

August 21, 2011

Condition was poor today.  I was only able to capture one image before clouds rolled in.

Nothing much happening in this region.  Both the SEB and NEB are dark red.   The STrZ is also hazy.

 

August 20, 2011

Condition was a little unstable this morning with moments of good seeing.

Oval BA is rising on this image.  Note the dark halo around BA. It still has an orange tinge.  The SEB is still very complex.

The NEB is still dark.  It is quiet in this region of the NEB. 

August 19, 2011

Seeing was again excellent this morning.

The GRS is well resolved.  Note the details inside the GRS!  The GRS halo is very dark. Note the tiny dark oval south of the GRS that is getting squished!  The GRS wake is very complex!

THe NEB has a huge dark spot.  The NTB looks faded on the visible light but dark on methane band.

August 18, 2011

Seeing was good this morning.  I was still having dew problem.  This time around I was armed with a hair dryer!

Oval BA is now orange in color.  It seem like all 3 red ovals have lost their color.    There is still a small white center on BA.  The bright spot following BA is Europa. 

The SEB is dark and broad.  The STrZ is also reddish.  The NEB is dark red.  Note the huge white spot on the NEBn.  Is this White Oval Z?  It looks like it's about to gobble up a small white spot.

August 17, 2011

Seeing was excellent this morning.

The GRS looks orange. Not as red as usual.  Note the features inside the GRS.  Note the dark spots inside.  The GRS halo is very dark.  The wake of the  GRS is very  complex.   

The NEB is still very red.  Note there are bright outbreak spots on the NEBs. 

Ganymede can be seen north of the GRS.  It is well resolved.

August 16, 2011

Seeing was excellent this morning.  These are probably my best images so far this season.

Note the two dark ovals on the NEB (CM).  The are on the verge of merging!!  The EZ looks very complex.

The SEB is very complex.  Note the tiny white ovals lining up on the southern edge of the SEB. The STrZ is reddish.

Also note the the red ring of the NNTZ LRS is visible in these images!!   So the news of it's demise was a bit premature.

August 11, 2011

Seeing was excellent this morning. 

The STrZ is dark.  There is a reddish haze over it.  The SEB is dark and complex.  Note the dark band south of the SEB. 

The NEB is dark.  Note the two small red ovals at the CM of the NEB.  Will they  merge?

Note the reddish feature on the NTBn.  The NNTZ LRS can be seen.  The reddish ring around it seem to have disappeared.  It seems to also have lost it's reddish color.  Should this now be called the LWS instead of LRS?

August 6, 2011

Seeing was good this morning.   I was surprised that transparency was dropping even though the sky was very clear.  There was dew on my corrector!

Oval BA  is setting on these images.  Oval BA is still red.  The STrD id dark and a little reddish.  The SEB is very complex.  Both the northern and southern edge is very dark. 

The NEB is dark.  Note the large white spot on the NEBn.

August 5, 2011

Seeing was very bad this morning.   I had to also deal with clouds.

The GRS is setting in this image. 

 

 

August 4, 2011

Seeing was again terrible this morning. 

Note the small dark oval on the STrZ.  The STrZ look dark.  The SEB is red and very busy.  The NEB is dark red but narrow. 

Note the reddish barges at the NTB.  NNTZ LRS can be seen in the northern hemisphere.  It is bright in methane band. 

August 3, 2011

Seeing was terrible this morning.   The SEB is dark.  No sign of outbreaks here.   Oval BA is rising on the left as can be seen on the methane band images. 

The NEB is dark but narrow.  It is interesting to note than the NTB is dark on methane band even though it is barely visible in visible wavelengths.

 

August 2, 2011

It's been over 2 weeks since my last image.  My notebook died two weeks ago.  Fortunately, I was able to have it fixed.  Last week, I was in Chiang Mai, Thailand to attend the 11th Asia Pacific  International Astronomical Union Meeting! 

Seeing this morning wasn't great but I was able to get a decent red and green channels.  Blue is still terrible.

The GRS is prominent in these images.  The area around the GRS is very busy.  The GRS is very bright in CH4. 

Note the huge dark oval on the NEB.   The EZ looks very busy.  Note the bright ovals on the NNTZ in CH4. The brightest spot is the NNTZ LRS.
