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.

May 29, 2017 

I had an interesting imaging run today.  The sky was mostly cloudy except for a patch around Jupiter.  It was a surreal because it stayed that way for close to an hour but a bit scary because lighting was flashing around me.  There were some stray clouds that passed by Jupiter so transparency was variable. Seeing was below average.

The GRS is well resolved with its reddish core and dark edges visible.  The wake of the GRS is very turbulent! The NEB looks quiet in this region.

May 28, 2017 

The sky was overcast  most of today but it cleared up early this evening.   Seeing was variable and so was transparency.

This images show the region that was hit by an impact yesterday.   There is no brightening of the impact region in methane band and nor is there any noticeable impact remnant.  I guess that was another bolinde.

Oval BA is prominent and teh ring is well resolved.   The SEB shows the mid SEB outbreak.    The SEB dark red spot and the STB Ghost can be seen rising. These two features are the dark spot and the dark streak respectively.  The NEB shows the WS-1 spot.


May 27, 2017 

Condition continue to be challenging today.  Seeing and transparency was variable due to clouds.

The two SEB outbreaks can be seen in these images.  The mid-SEB outbreak can be seen on the left.  While the outbreak at the wake of the GRS is on the right.  The dark streaks on the SEB are also prominent in the methane band image.   The South Polar red spot can be seen.

May 26, 2017 

The sky was mostly cloudy.  I tried to image Jupiter.  Seeing was okay but transparency was terrible!

The GRS is rising on the left while Oval BA is setting on the right.  The STB Ghost is moving away from the GRS.  The light blue feature above the STB Ghost is still there.  The NEBn WS-1 Spot still has a peach color with a dark center.


May 21, 2017 

Terrible conditions today.  The sky was mostly overcast.  I had to image Jupiter through clouds.  I had to crank up gain so high to compensate the low transparency.  Unfortunately, I was only able to capture 3 sets of RGB before the clouds won.

The GRS the the main feature in this image.   The STB Ghost and the light blue feature north of the STB Ghost can still be seen.  The NEBn WS-1 still has the reddish color.


May 20, 2017 

I wasn't sure that I could image today.  The sky was overcast.  The clouds thinned out in the area of Jupiter.  But transparency was very poor.  Fortunately seeing was good.

The SEB outbreak is still going strong.  The STB Spectre can be seen setting on the right.


May 19, 2017 

Seeing was perfect today but transparency was poor due to clouds.

The GRS is well resolved in these images.  Note the details inside the GRS.  There are some IR bright spots inside the GRS.  The STB Ghost is still very dark in CH4 band.   Note the light blue feature north of the STB Ghost.  Some white spots can be seen in the South Pole.  The dark red spot preceding the GRS is very dark in CH4 band.

Note the reddish spot on the NEB.  This spot is bright in CH4 band. 

May 18, 2017 

After so many days of bad weather the sky was surprisingly clear tonight.  Seeing was average when I started imaging but improved as Jupiter got higher.

The SEB outbreak is still very active and very turbulent.  Oval BA is rising on the left on the later images.  

The area on the EZ at the CM which is very bright in Methane Band.   The methane band image shows a lot of details especially at the region close to the north pole!

May 17, 2017 

We had a strong torrential downpour early this evening.  I wasn't optimistic this evening but the area around Jupiter cleared up as Jupiter passed the meridian.   I had some second thoughts with imaging as lightning was flashing around us.  Seeing was variable but transparency was good during the duration of this run.

This is the target region for Juno during PJ6!  The STB Spectre can be seen just before the CM.  This feature is dark in Methane band but note the bright spot just above this feature.  The south polar red spot can also be seen.

The SEB shows the two outbreaks on opposite limbs.   The NEB has some rifting and a small bright outbreak.

May 16, 2017 

I had to rush imaging session this evening.  There was a hole in the clouds.  Seeing was excellent but transparency was very poor.  After taking the last image set, the sky became overcast!

Oval BA has a very thin orange ring.  There are some details resolved inside.  The mid-SEB outbreak is still very active.  Note the oval on the NEBn which has a dark spot in the middle.  I could not capture any Methane band image because of the low transparency.


May 14, 2017 

I was not sure I could image today.   It was totally overcast early this evening.   They sky cleared up close to 9pm today.

The GRS is well resolved today.  The wake of the GRS is very turbulent!  In the methane band, there is a bright extention on the GRS.

There are a lot of rifts on the NEB. 

May 12, 2017 

Seeing was variable today.  

These images show the GRS and it's wake.  The NEB has complex rifts in this region.

May 10, 2017 

Conditions continue to be challenging today.   Seeing was  average but it was very windy. 

The STB Spectre can be seen close to the CM.  The two SEB Outbreaks can be seen on the opposite sides!  The South Polar red spot can also be seen.  There are two bright outbreaks on the NEB.

May 8, 2017 

Condition was very poor today.  The sky was mostly covered with clouds.  I had to take these image through clouds!  Seeing was mediocre.  I was imaging with Tomio Akutsu this evening.

The SEB outbreak is very active in this region.  Io and it's shadow can be seen on the NEB.


May 4, 2017 

The sky cleared today.  Condition was challenging because of strong winds and clouds.  But seeing was quite good.

The GRS is well resolved.  The light blue disturbance caused by the STB Ghost is still there.  The STB Ghost is not as dark in CH4!!  Except for the dark part close to the GRS, the other parts seem to be fading!  Note the trio tiny ovals on the SSTB!  Will they merge into one?

The NEB is still active with a lot of outbreak activity.  It is nice to see the tiny ovals in the area close to the poles. 

May 2, 2017 

Exceptional conditions today!  

The GRS is resolved to it's core!  The STB Ghost passage with the GRS has created an interesting light blue disturbance!  In the methane band, there seems to be a bright oval inside this feature.  The small red spot preceding the GRS is very dark in methane band! 

There is a bright outbreak at the NEB.   Small ovals are resolved in the polar regions.

May 1, 2017 

Excellent conditions today.

The SEB outbreak is still going strong.   The  NEB is also very active.  Io's shadow is crossing the NEB.  Io is also resolved.

In the Methane Band, there is a curious double oval on the NNTZ.  But in the RGB image there is only one spot!  I have checked all 4 pre-derotated data and they show this double spot!
