JUPITER 2016/17 SEASON

By Christopher Go

JUNO in now on orbit in Jupiter.  Unfortunately it is currently stuck on a 54 day orbit due to some problems with it's thruster valves. 

All images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount.   I used a Celestron Skyris Protype Camera starting April 2016.  Images taken after March 30 were taken using a prototype Skyris camera.  RGB is done using a set of Chroma Technology RGB filters on a Starlight Xpress Motorized filter wheel.  Methane band images are done using a Chroma Methane Band filter (889nm  18nm bandpass).  UV images are done using a Astrodon UV filter.   Amplification is done using an Astrophysics Advance Convertible Barlow working at 2.0X.

Image acquisition was done using  Torsten Edelmann's Firecapture 2.5beta 64bit software.  All images are NORTH UP!   The Skyris  camera is controlled by a Thinkpad T530 through the USB 3.0 port.  Processing was done using AutoStakkert! and Registax.

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

March 25, 2017 

I had 2 imaging runs today.  The first image was taken in exceptional seeing.   Unfortunately, clouds rolled in before I could take the IR and CH4 image so I had to stop.   One hour after, the sky cleared so I did another run.  Seeing wasn't as good but had some decent images.

The first image shows the approximate target region of Juno for Perijove 5 on March 27.   The NEB is very chaotic in this region with multiple outburst!   The SEB shows the effect of the mid-SEB outbreak.  It is nice to see the small white ovals close to the polar area.  These will be imaged by Juno.  The south polar red spot can also be seen.   The STB Spectre can be seen just before the CM on the first image.  This feature is very dark in Methane Band.

The second image shows the mid-SEB outbreak rising on the left.

March 24, 2017 

Condition was perfect today.  Unfortunately, it was cut short by clouds.

These are stunning images of Jupiter with the Great Red Spot which is well resolved.  Note the complex wake following the GRS.   In the CH4 image, there is a curious bright spot on the SEBn.  This is the first time I have seen an outbreak in that area.  Note the STB Ghost is making a pass below the GRS!

Note the ovals on the NEBn.  There is a curious oval  with a red core on the NTrZ!  This oval is marginally bright in CH4.  The NNTZ LRS is also very distinct and bright in CH4.

March 23, 2017 

Seeing was variable to day but I was lucky to have some very good data!

These images show the mid-SEB outbreak at its full extent.   This feature is very turbulent and consist of multiple outbreaks.  These outbreaks are the bright spots in the Methane Band image.  Oval BA can be seen rising on the left.

The region preceding the bright rift on the NEB looks quiet.    Note the ovals on the NEBn.

March 22, 2017 

Seeing was good this morning.

This is the region following the GRS.  Note the bright outbreaks on the left.  These outbreaks is bright in CH4.  The NEB is also very active in this region with major outbreaks.

March 21, 2017 

Seeing was excellent today but transparency was variable due to thin clouds and haze.

The GRS is well resolved in these images.  The core and the vortex can be resolved.  Oval BA color is a bit pale.  Note the bright outbreak in the wake of the GRS rising on the left.  The NEB looks very active with a lot of rifting. 

 

March 20, 2017 

Very poor conditions today.  Seeing was horrible and transparency was poor.

The effects of the mid-SEB outbreak can be seen in these images.   The NEB looks turbulent in the area close to the CM.

 

March 18, 2017 

Seeing was much better today. 

The SEB outbreak looks very chaotic in this region.   The blue STB Spectre can be seen setting on the right.  The NEB is wide and active in this region.

 

March 17, 2017 

Conditions here have been terrible the last few weeks.  The NE monsoon returned giving us a lot of cloudy skies.  I got my first clearing this morning.  Unfortunately, seeing was terrible and winds were gusty!

Note the SEB outbreaks in this region.  The SEB is really active this year.  This outbreak is on the opposite side of Jupiter from  the outbreak that Phil Miles discovered a few months ago!  This outbreak is also bright in CH4!

The NEB has a lot of rifting on active on it's south side.   Yet it is very narrow in this region.

 

March 4, 2017 

Very poor conditions today.  I had to image through clouds and transparency was very poor.

Oval BA can be seen at the CM while the GRS is rising on the right.   The SEB outbreak can also be seen.  Note the rift system on the NEB.

 

March 2, 2017 

Seeing was unstable today.   Clouds had to interrupt my imaging session midway.

The GRS is prominent.  The dark core is resolved but the other features are not very clear.   The STB Ghost is now on the left, next to the GRS.   On the Methane Band image, there is a bright extension on the right side of the GRS.  The NEB outbreak has now formed a long rift.

March 1, 2017 

Condition was challenging today because of clouds.  Seeing was good but transparency was variable.

The SEB outbreak is very chaotic in this region.   Oval BA is rising on the left.   The NEB has a lot of rift activity.
