JUPITER 2017/18 SEASON

By Christopher Go

All images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount.  A QHY 290M camera was used is these images.    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!     Processing was done using AutoStakkert! and Registax.

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

January 11, 2018 

The sky was clear this morning.  Seeing was good.

Note the bright spot north of the dark barge on the SEB.  Will this start an SEB outbreak?  The CH4 image doesn't show any brightening so it is premature to call this an outbreak.  We will see in the next few days if this feature will brighten up on CH4.  This feature is currently located at around  CM2: 185.

Note the dark barge on the STrZ just southwest of the SEB red barge.  The feature seems to show a "hump" on its surround belt.   Nothing in the CH4 however.

The NEB looks quiet in the region.  There are some brightening close to the EZ festoons.  

January 7, 2018 

The sky was mostly cloudy today.  I probably should have gone back to bed because imaging was very frustrating with clouds passing Jupiter.

The GRS and the South Tropical Disturbance (STrD) are prominent in these images.   There seems to be some SEB outbreak north of the STrD.    Io is the bright patch above the GRS on the NEBn.

 

January 6, 2018 

The sky was partially cloudy today with a bit of haze.  I hesitated a bit to image because of the conditions.  I was lucky to capture a set of RGB before the sky was overcast.  Seeing was not great and transparency was very poor.

The dark red barge with a bright halo on the SEB looks interesting.   The NEBn has cyclones and anti-cyclones lining up.  The NEBn is also light in color.  Is the NEB shrinking this season?

January 3, 2018 

Happy New Year!  Here are my first images for 2018!   Seeing was much better this morning.  Though it is still poor compared to my usual seeing due to Jupiter being so low in the sky.

Oval BA is prominent in these images.  The light orange ring can be seen.  The SEB looks turbulent in this region, while the NEB is not every active.  White Spot Z can be seen on the NEB. It still has a reddish hue.

December 30, 2017 

Very poor condition today due to a nearby low pressure system.

The SEB and NEB looks quiet in this region.  The NEB looks very wavy in methane band.

December 28, 2017 

Condition was still poor today.  Seeing was unstable as Jupiter is still very low.

The GRS is prominent in these images.  It has a strong orange color.  The STrZ Disturbance can be seen rising on the left.The NEB is quiet in this region.

December 24, 2017 

Merry Christmas!  It's Christmas morning here and I woke up early for a date with Jupiter!  Seeing was poor today.

The South Tropical Disturbance can be seen setting on this image.   This feature is dark in Methane Band.  The NEB is quiet in this region.  White Spot Z can be seen rising on the left.  It still has a light orange color.

December 20, 2017 

Condition still very unstable today.  I had a clearing before an upcoming storm.   A tropical cyclone is headed our way.

Oval BA can be seen setting on right.  Note the dark band on the STrZ.  THe SEBn is dark.  The outbreak that was seen last season seems to be gone.  There are a lot of anticyclonic white spots on the NEB!  Note the wavy look of the NEB in CH4.

December 18, 2017 

My first image of Jupiter this season.  Seeing was a bit unstable because Jupiter was very low.  I started imaging in IR and CH4.  Unfortunately, when I was ready to image RGB clouds rolled in.

This feature is prominent in the IR image.   Note the dark wavy pattern of the NEB in the CH4 image.
