JUPITER 2015/16 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.

January 21, 2017 

It has been more an a week since my image imaging run.  We are still have the NE monsoon which caused a lot of flooding and landslide here.   Seeing was variable and it was very windy.

The SEB outbreak is bright in CH4!   It also looks impressive in visible light.  Note the bright NEB outbreak.  The NTrZ looks reddish in visible light.   The NEB/NTrZ looks very chaotic in this region.  Europa's shadow is on the NTBn.

January 12, 2017 

It has been quite some time since my last image.   We had a tropical depression which decided to linger for a few days.  I had a lucky break this morning.   There was a clearing in the clouds before the whole sky went overcast again.  Seeing was terrible and transparency variable.  I had to capture a lot of data to get a decent image.

The SEB outbreak has grown into a complex system.  The GRS is prominent and it's dark core is resolved.  Oval BA is at the CM and it has a light orange color.  The NEB is dark in this region.  There are complex rifts.  The NTB looks quiet.

January 5, 2017 

We are still getting the winter northerly winds.  Seeing was mediocre and transparency was poor due to haze. We had gusty conditions!

The GRS is prominent in these images.   There are still outbreaks on the wake of the GRS.     Oval BA still has an orange color.   The SEB Outbreak can be seein setting on the right.  There are multiple outbreaks on the NEB. 

January 3, 2017 

It was still very windy today.  Seeing was variable and I had to deal with intermittent clouds.

The GRS is setting on the right.  The f side of the GRS is not as turbulent.   In fact, it looks very quiet.   The STB Ghost can be seen at the CM.

Note the bright outbreak on the NEB.

 

January 2, 2017 

Condition was very bad today.  Seeing was better but transparency was very poor.

The SEB outbreak is rising on the left.  The STB Spectre is setting on the right.

The NEB/NTrZ is very turbulent!   There are a lot of complex rift activity.  Seems like the reddish material from the NEB is spilling over the NTrZ.  

December 31, 2016 

Happy New Year!  It is 2017 here in Cebu.  Seeing was very poor here and it was very windy.

Congrats to Phil Miles for catching the SEB outbreak.  This outbreak has grown as expected.    Note its bright white color.  This feature is marginally bright in CH4.  The GRS and Oval BA can be seen. But seeing was poor to resolve any good details. 

The NEB has a lot of rift activity.

December 30, 2016 

It was very windy today.   Seeing was poor.  This will be my last image for 2016.  It is New Year's Eve here in Cebu.  Happy New Year!

The SPR Red Spot can be seen.   The NEB has a pale color in this region.  Note the dark features on the NTrZ.  They look like the EZ feestons!   The SEB should get exciting soon as Phil Miles just discovered an outbreak on the other side of the planet.

December 29, 2016 

Condition was a bit frustrating this morning.  There was haze that lowered transparency.  Seeing was also very unstable.

The GRS is well resolved.  Its amazing how oval it has become!   The wake of the GRS is very complex.   Oval BA can be seen setting on the right.  The STB Ghost is rising on the left.

Note the bright outbreak on the NEBn.  This feature has become more complex.  Note how dark the NEB is in this region.  

December 28, 2016 

Finally the sky is clear again after a Super Typhoon Nock ten.   Seeing was variable.  But improved as Jupiter got higher.

The SEB looks normal.  Note the bright feature on the SEB at the CM of the 2nd image.  The STB Spectre can be seen as a dark bluish feature.  The NEB has very light color in this region!  Is it fading?  The NTB has a red belt.

December 24, 2016 

Merry Christmas! It is Christmas morning here in Cebu.  I was not expecting to image this morning because Super Typhoon Nock Ten is close by. It will make landfall in Luzon this afternoon.  We will be ok here in the Visayas with land fall more than 300 miles away.  When I went out this morning, there was a clearing in the clouds with Jupiter shining bright and inviting!  However, condition was terrible today because of the Super Typhoon.  I could only get IR and CH4 image because the color images were just mucky because to terrible seeing.

The GRS and Oval BA can be see in these images.  The wake of the GRS is very complex.   There seem to be some rift and outbreak activity on the NEB.

 

December 23, 2016 

Merry Christmas!

The calm before the storm!   Condition was very bad here due to a powerful typhoon on the Pacific.   Seeing was very bad and transparency was poor due to thin clouds. 

The NTB red belt is very well defined.  The NTrZ is still very disturbed due to the outbreak last October.  The NEB and SEB looks quiet.

December 11, 2016 

Seeing was unstable when I started imaging.   So I started imaging in IR and Methane Band before imaging in RGB.  Seeing improved as Jupiter got higher.   But clouds started in come in during the later part of my RGB run.  

Just got word from Glenn Orton that the Juno's PJ3 was a success and that data is now being downloaded from the spacecraft.

The STB Spectre can be seen on the left.  The South Polar red spot is close to the CM on the color image.  I hope that Juno captured this spot during it's polar flyby.   The SEB and NEB looks normal.   Note the long dark streaks on the NTrZ.

December 10, 2016 

Seeing variable this morning.   I had to deal with high humidity.   Fortunately, my dew shield worked perfectly.  These images are about 2 Jupiter rotation before Juno's 3rd Perijove.   This is the approximate region that Juno will image tomorrow!

The GRS and Oval BA are setting on these images.  Note the complex wake of the GRS.   Juno will try to get a close up of this region tomorrow.   Note the new outbreak on the NEB.   The NEB White Spot Z seem to be embedded with NEB material.  The NTrZ is very chaotic due to the recent outbreak.  Looking forward to Juno's close ups...   The STB Ghost is very dark in CH4!

Ganymede can be seen on the lower left of Jupiter.

December 9, 2016 

Seeing was excellent this morning.   Unfortunately, transparency was very poor because of clouds.

The STB Spectre can be seen just past the CM.   The northern and southern edges of the SEB shows the turbulence from the GRS.   The NEB is dark.    Note the dark streaks on the NTrZ.   Are these remnants of the NTB outbreak.   The NTB shows a distinct reddish band.

 

December 6, 2016 

Seeing was variable today.  There were also some clouds that reduced transparency.

The South Polar Red Spot is prominent in these images.  This spot is bright in CH4.  The NEB and SEB are quiet in this region.  

December 5, 2016 

Condition was good today.  But still below average.  Transparency was variable.

The GRS is well resolved.  The wake of the GRS is very complex.  Oval BA is setting on the right.  

The NEB has a dark red color.   Note the complex rift above the GRS.   White Spot Z has a dark color similar to the NTrZ.  This spot is not bright in CH4.  The NTB band is dark red.

November 30, 2016 

I had a big scare last night.  We had a very strong gust and rain that almost toppled my C14/AP900!  I was out trying it keep it from falling.   Thinking about it now, it was a stupid thing to do but my system is ok.  When I woke up this morning the sky was surprisingly clear!  Seeing was however still unstable.   When I plugged my mount, it would not turn on!  Fortunately I had a spare power cable!

The GRS is at the CM and has a very strong red color.   Oval BA just passed the GRS and the red ring is distinct!  Note the complex rift on the NEB.  The NTB's red band is distinct.  Note the dark spot on the NNTZ.  This feature seem to be CH4 bright!

November 29, 2016 

Seeing was poor today.  

Ganymede's shadow is transiting.  The NTB has a distinct dark red color.   The NEB and SEB is quiet in this region.

 

November 28, 2016 

Seeing was much better this morning.  

The NTB has its reddish band restored.   The NTrZ has a yellowish color with dark streaks.  These are probably remnants of the outbreak last month.   The NEB is dark red but narrow in this region.   There are no outbreaks here.  The SEB is turbulent in this region.  The STB Spectre can be seen as the bluish streak at the CM.

 

November 21, 2016 

Condition was still unstable today.  Jupiter was around 40deg when I took these images.

The SEB has a very light shade.  The STB Ghost can be seen close to the CM in the first image.  This feature is very dark in CH4.

The NEB is dark and wide in this region.  Note the reddish NTB.

November 12, 2016 

Condition was poor today due to NW wind. 

The SEB is quiet in this region.   THe NEB is dark.  Not outbreaks here.   The NTB is dark.  

November 10, 2016 

Condition was much better today.  Finally able to get a decent color images of Jupiter.  Jupiter was around 30deg when I took these images.  My CH4 image did not turn out well because the sun rose when I took this image and part of the video had its background washed out!

The SEB is quiet in this image.  Note the bright feature at the mid-SEB at the CM.   The STB Spectre is the blue feature on the STB.  This feature is dark in CH4.  The NEB is dark red and narrow.  Io and it's shadow is on the NEB.   THE NTB still has the dark remnants of the outbreak that was seen last month.  This region is no longer bright in CH4.

October 30, 2016 

Here is an early start to the Jupiter season.  Seeing wasn't very good because Jupiter was less than 20deg above the horizon.

The GRS can be seen setting on the right.
