JUPITER 2014/2015 SEASON

By Christopher Go

Late start on Jupiter this year.  Hoping for an exciting year with Jupiter.  The GRS is shrinking!

All images were taken using a Celestron  C14  mounted on an AP900GTO mount.  A Skyris 132M camera are used.  RGB is done using a set of Chroma Technology RGB filters on 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 2.0X.

Image acquisition was done using  Torsten Edelmann's Firecapture 2.3 software.  All images are NORTH UP!   The Skyris 132m is controlled by a Thinkpad T520 through the USB port.  Processing was done using AutoStakkert and Registax.

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

Seeing was perfect this morning!  But I had to fight dew!  I did not get my dew shield so I had to wipe my corrector plate for every RGB sequence. 

The NEB is very active in this region.  Note the bright feature on the EZn close to the CM.  This area is bright and prominent in CH4!  The outbreaks in the NEB are creating a lot of rifts.

Note the red barge on the NTB.

The SEB is very dark and complex.

Seeing was good this morning with periods of perfect seeing.

The GRS is prominent in this image.  Details can be seen inside the GRS.    The GRS halo has a light orange color!  The border between the GRS and SEB has a dark red arc.  The SEB outbreak is pushing into the GRS.  Note the red tadpole like feature following the GRS. 

Oval BA is setting in these images and it still has a light orange tinge. 

There are outbreaks appearing on the NEB.  The dark moon Callisto can be seen to the right of Jupiter.  I had to readjust the brightness of Callisto to make it more visible.  Also because of derotation, I had to put Callisto in manually so it's position might be slightly off.

Seeing was excellent this morning.  Unfortunately, I had to shorten my imaging session because of clouds.  I had to salvage my CH4 image.

Note the small dark red spots on the SEB.   The NEB looks very complex.  The outbreak has produced a lot of rifts around the  NEB.  The Oval Z is rising on this image.  There is a reddish tinge on this Oval.  In CH4, this oval has a slight brightening but it isn't as bright as last season.

November 12, 2014

Conditions were variable this morning.  The sky was hazy and seeing was variable. 

The SEB looks very complex in this region.   The NEB is quiet.   The Spot Z on the NEB has a light orange hue.  Spot Z surprisingly is not bright in Methane Band.  Note the large white spot on the NNTB which is bright in Methane band.

November 10, 2014

Seeing was good this morning.

Europa can be seen exciting the Jovian disk.  The SEB looks complex in this region. This is the region before the GRS.   The NEB looks quiet here.

November 8, 2014

My first image of Jupiter for this season.  I had a late start because conditions here in Cebu was just horrible because of monsoon season.  I have also just returned from my travels.  Seeing was just okay this morning with some clouds.

The GRS and Oval BA are prominent in these images and are just past conjunction.  Note the SEB outbreaks are now pushing close to the GRS.  The red center of the GRS has shrunk considerably!   Note the very dark halo  as the outbreak pushing to the GRS!  Note the dark spots on the STrZ preceding the GRS.

Oval BA still has an light orange annulus ring.    Note the CH4 brights spot between the GRS and Oval BA!

The NEB has a bright outbreak.  Note the dark red barge on the NTB.
