JUPITER MARCH/APRIL 2017

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.    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.

April 30, 2017 

This is my 15th straight imaging run for Jupiter.  Seeing was average.

These images show the region following the GRS.  Note the bright SEB outbreak region close to the CM.   The GRS is on the eastern edge of the SEB.  The red spot close to the south pole is also visible.

April 29, 2017 

I had a crazy evening.  After powering up the mount and trying to point my mount to Jupiter, the E-W button were reversed.  In fact, the mount was tracking from W-E!  Seems like the mount was stuck in south.  I took out my mount controller and as I shook it, water poured out!  I was in panic!  I spent some time opening my mount controller, fortunately, it was dry inside.  Water was limited in the area of the N-S swich which I had to dry with a hair dryer.  After that the mount worked fine again!

Seeing was  variable this evening with periods of very good seeing.  I had to be patient for those times.

The GRS  is rising on the left and the dark core is resolved.  The STB Ghost is now headed towards Oval BA.  It would be interesting to see what will happen when they collide with each other!  The NEB has a lot of outbreaks.

April 28, 2017 

Condition was still bad today.  Seeing was ok but transparency was poor.  

The two N4 ovals are stuck right next to each other.  The NEB has some bright rifting.   The SEB shows the edge of two outbreaks on each side.   The STB Spectre can be seen close to the CM.   The south polar red spot is also resolved.

 

April 27, 2017 

I wasn't sure I would be able to image today.  We had a heavy downpour that caused some flooding in our area.  The sky cleared up though.  But transparency was very poor because of thin clouds.  I had to take a lot of image to get this.

The GRS is rising on the left while Oval BA is setting on the right.   The STB Ghost can be seen preceding the GRS.   The NEB looks quiet in this region.

 

April 26, 2017 

Excellent seeing today.  

Note the two ovals which I had previously observed during the last few days.  They are now right next to each other.  The NEB is active in this region.  Note the strange looking oval on the NEBn. There are multiple outbreaks on the NEB.

THe SEB shows a bright outbreak on the mid-SEB.   There are also blood red barges on the SEBs.  The SEB Spectre is setting on the left.

April 25, 2017 

Seeing was variable this evening.   I had to image early because I plan to image Saturn tomorrow dawn.

The GRS is setting on these images.  The wake of the GRS is very turbulent here.   There are also outbreaks on the NEB.

April 24, 2017 

Condition was good this evening.  I had a little excitement though.  I was a bit startled when something  splashed into my monitor.  A bat decided to unload it's droppings into my laptop screen...

Oval BA is well resolved.  The red ring and the white core can clearly be seen.  The mid-SEB outbreak is still going strong.  As Anthony Wesley has noted, the dark areas on the SEB has a strange olive hue. The NEB is also active with multiple outbreaks. 

April 23, 2017 

It was clear when I started imaging.  Seeing was unstable.  Clouds suddenly appeared and the sky was overcast!   I was able to take the later image through a hole in the cloud.  Seeing was excellent during that time.

Note the two white ovals close to the north polar region rising on the left.  These might merge any day now.   The NEB has a lot of bright outbreaks and complex rifting.  One can see the two outbreaks on the SEB.  The mid-SEB outbreak is rising on the left. While the outbreak on the side of the wake of the GRS is setting on the right.  The STB Spectre can also be seen as a bluish feature.  Note the red spot close to the South Pole.

April 22, 2017 

Frustrating conditions today.  It was mostly cloudy.   I had to image in holes in the clouds.

The STB Ghost looks interesting.  It is now past the GRS.  It's color has become dark blue with a reddish tinge.  The dark red spot on the mid-SEB preceding the GRS is very dark in Methane Band.  The NEB has a lot of outbreaks as the EZ festoons interact with the NEBs.

April 21, 2017 

Excellent conditions today.

Note the two white ovals next to each other close to the North Polar Region.   Will they merge?  These ovals are bright in Methane Band!  The tiny red spot on the NNTZ is bright in methane band.  The NEBn Spot Z is currently embedded in the NEB and very close to a very turbulent area.  This spot is suprisingly bright in methane band again!  Last time this happened, this spot turned pink!

There is a bright outbreak in the SEB.   The STB Spectre can also be seen.

April 20, 2017 

Seeing was good today.

The GRS is well resolved in these images.  Note the dark red core and the surrounding vortices are clearly visible.   The wake of the GRS is very turbulent.   The STB Ghost has passed the GRS and it is the dark elongated in the methane band image SE of the GRS.  The NEB is very active in this region with multiple outbreaks.  The NNTZ Little White Spot (formerly the Little Red Spot) can be seen.  It's red color is completely gone! 

April 19, 2017 

Condition was good today.

The mid-SEB outbreak is well shown in these images.  It is very complex and turbulent.   Oval BA can be seen on the left.   The NEB is also active in this region..  Note the bright spot on the methane band image setting on the right.  This is White Spot Z!    Lost of features resolved on the temperate and polar regions!

April 18, 2017 

Condition was just average today.  

This is the region showing the wake of the GRS.   There is a bright outbreak on the SEB close to the edge of the wake.   This feature is also bright in Methane Band.  The South Polar Red Spot can also be seen.  This spot is bright in methane band.  The NEB has complex rifts in this region.

April 17, 2017 

Excellent conditions today.  Though transparency was not prefect because of haze. 

The Red Oval BA is very well resolved and it's white core can clearly be seen.    The GRS is rising on the left.   The STB Ghost has passed the GRS and is headed towards Oval BA?  It would be interesting to see what will happen when they meet!

The SEB is very turbulent due to the mid-SEB outbreak.   The NEB is also very active here with multiple outbreaks.  Seeing was so good today that the small dark and white ovals on the temperate to polar regions are well resolved!

April 16, 2017 

Happy Easter.  I was not sure I could image today.  We just had a tropical depression pass by earlier today.  Fortunately, the sky cleared early in the evening!  Seeing was variable and transparency was poor because of haze.

The NEB has a lot of activity in this region.  Note the complex rift and the bright outbreak.   The SEB Outbreak is rising on the left.  Note the dark red spots on the SEB.  The STB Spectre can be seen close to the CM.

April 10, 2017 

Perfect conditions today.  I was fortunate to have the GRS in view.  This will be my last image till Saturday as I will be out on vacation.

The GRS is well resolved.  The STB Ghost is now passing the GRS.  The south side of the GRS is very dark in CH4 probably interacting with the STB Ghost.  There is a curious outbreak on the NEBn.

April 9, 2017 

Excellent conditions this evening!   Seeing was perfect and the sky was totally clear!

The SEB outbreak can be see well.  Note the dark structures that is prominent in the CH4 image!  The STB Spectre can be also see as the bluish feature.  Most fo these feature is very dark in CH4 but there is current like a bright spot on it's northern edge!

The NEB White Spot Z is embedded in a turbulent section of the NEB.  It is interesting to note that it is again bright in CH4!  This happened a few years ago and this spot turned PINK!  Will it happen again?

April 8, 2017 

Seeing was very bad during the start of my imaging run.  But it improved as Jupiter got higher.

The GRS is setting on these images.  The wake is very complex.  The bright outbreak on the mid-SEB is still going strong!  This outbreak is very bright in Methane Band.  The NEB is very active in this region with outbreaks and complex rifts.

April 7, 2017 

The last weeks have been terrible here.  We were having the NE monsoon again.  Fortunately the rain stopped on Jupiter's Opposition day! Transparency was poor though because of clouds.  Seeing was variable and I was able to salvage some data to get these images.

The SEB outbreak can be seen and it still very turbulent.   The outbreak area is bright in Methane band just north of Oval BA.  Oval BA's orange ring is prominent.  

March 29, 2017 

The last few days had been terrible for imaging due to a low pressure area.  A few minutes before I started imaging there was a heavy downpour!  Very poor imaging conditions today.

Te GRS is setting here and the wake of the GRS is very long turbulent.      The NEB looks calm in this region.

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.
