JUPITER 2011/2012 SEASON

By Christopher Go

A new season of Jupiter!  The SEB has revived from the outbreak which started last November.

All images were taken using a Celestron C11 or C14 (after July 2011)  mounted on an AP900GTO mount.  A  Point Grey Research Flea3 cameras were used.  RGB is done using a Homeyer Motorized filter wheel.  Methane band images are done using a Custom Scientific Methane Band filter (889nm  18nm bandpass) provided to me by the University of California at Berkeley.  UV images are done using a Astrodon UV filter.   Amplification is done using an Astrophysics Convertible Barlow working at 2.5X.

Image acquisition was done using  Torsten Edelmann's Firecapture software.  All images are NORTH UP after this date!   The Flea3 is controlled by a Thinkpad T520 through a Firewire B adapter.

These images were taken at Banilad,  Cebu City, Philippines.

Seeing was variable this evening.  But I was able to get two very good image. I did not use derotation because the result wasn't as good as a single image.

One thing apparent is that Oval BA is approaching the GRS!!  Conjunction should occur between June to August this year depending on how fast Oval BA will move towards the GRS.

Oval BA's ring is apparent and has an orange hue now.    The wake of the GRS is very complex.  The embedded in the wake has grown a lot since my image in Jan 22.  This outbreak area is  bright in methane band.  This outbreak pushes gas towards the GRS creating the wake.

The NEB is still narrow.  The north temperate zone is very quiet.

Transparency was very poor this evening.  I was only able to salvage one image.

Jupiter is still the same.  The SEB is complex and wide while the NEB is narrow.  Nothing special in this region.

Seeing was good when I started imaging but deteriorated as Jupiter went over our hot roof.

The GRS is setting.  The area preceding the GRS is very red.  While the area following the GRS is very turbulent.   Note the bright outbreak spot following the GRS.  The dark ring is still surrounding the GRS.

The NEB is narrow.

Condition was very unstable this evening. 

NNTZ LRS is prominent in Methane band but is hard to see in visible light.  The NEB is still narrow.  While the SEB is very active.

Condition was good this evening.  But I only had a short window before clouds rolled in and cut short my session.

Oval BA can be seen in these images.  It is very bright in Methane Band but it's red ring is very faint.  The SSTB oval southwest of BA is also bright in Methane Band.

 The SEB is very complex and dark.  While the NEB is narrow.  The north temperate region is very pale.

Seeing was much better this evening.  It was clear today.

The GRS is rising in these images.  The SEB is very dark with a lot of activity on it's north and south bounderies.

The NEB is very narrow.

It had been cloudy here for the last few days.  Tonight was mostly cloudy and I transparency was poor and variable!!

Ganymede and Europa could be seen on the southwest.  The SEB is still very dark and active while the NEB is very narrow now!

It was partially cloudy this evening.  I had to image between clouds and seeing was very variable.

The NEB is very dark.  The NEB is a bit wider here.  Note the large white spot north of the dark oval on the NEBn.

Condition was very poor this evening.  Seeing very unstable.

It's the usual active SEB and the narrow and quiet NEB.  The bright spot in Methane Band is the NNTZ LRS.

It was mostly cloudy this evening.  Seeing and transparency was very poor.

The GRS is rising in this image.  The SEB is dark.  The NEB still narrow with the dark ovals getting bigger!
