JUPITER 2019 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.

March 17, 2019
It was very blustery this morning.   Seeing was good but wind gust was a problem.

The GRS can be see with its very dark color and the center core resolved.  The wake of the GRS is very turbulent.   Note the dark red strip on the SEB preceding the GRS.  The EZ still has the reddish haze and the SEBn following the GRS has a yellow color similar to the EZ.

The NEB is quiet in this region.  White Oval Z can been seen above the GRS on the NEBn.    Note the dark brown barge on the NNTZ on the right.  This feature was imaged by Juno recently.

March 15, 2019
Another day of unstable seeing.

The SEB in this regions looks like an extension of EZ.  The NEB has complex rifts but mostly quiet in this region.   Note the white oval at the NPR which is prominent in the IR image.

March 14, 2019
Seeing was so unstable this morning because of N winds. 

Oval BA can be clear seen on these images.  It still has a pale orange color.   The SEBn is very dark.  Note the oval feature just above the dark NEBn band at the CM of the first image.   This feature seem to be dark in methane band.   The GRS is rising on the left of the later images.   The NEB is quiet in this region.

3 moons are featured in these images.  Icy Europa is transiting at the North Temperate region of Jupiter.  Volcanic Io can be seen in the methane band image to the left of the GRS.   Ganymede is peeking out at the 7'o clock position of the 2nd color image.

March 12, 2019
Dew was a big problem this morning.  I had to wipe the corrector every 2 minutes!  Seeing was also variable.  I was lucky that there was a short span of good seeing.

THe GRS is well resolved in this image.  Note the details inside the GRS.  The SEB preceding the GRS is very deep red.  The wake of the GRS is very turbulent.  White Oval Z is on the NEBn above the GRS.

March 10, 2019
The sky was again hazy this morning.  Transparency was poor and seeing was variable.  Again no Methane Band image today due to poor transparency.

The GRS is setting on the right.  The wake of the GRS is turbulent.   The mid-EZ in this region shows the strong red haze.   The NEB is narrow and dark.  

March 9, 2019
I had to image through thin clouds this morning.  Seeing was fair but transparency was very poor.  I was unable to capture methane band data due to poor transparency.

Oval BA can be seen with a pale orange color.   Is it trying to turn red again?  The GRS can be seen peeking out of the left on the IR image.  There is an interesting barge on the SEBs just before the CM.   The SEBn is very turbulent in this region.  The reddish hue of the EZ is very strong in this region.   The NEB is quiet in this region.

 

March 8, 2019
Variable seeing again today.  I had to hand pick the good images for derotation.

This is the quiet side of Jupiter.   The SEB is very pale here and it almost seems to have the same color as the EZ.  The NEB has some rifting.  What is interesting to note is that the dark part of the NEB in Methane Band is very narrow!

March 7, 2019
Condition was variable today. Seeing was sometime excellent with periods of fuzzy seeing.  Transparency was also variable due to clouds.  But I am happy with the results today.

The GRS is prominent on this image..   The dark core is well resolved.   Note the dark streak on the p side of the GRS.  The wake of the GRS shows some outbreaks.  These are bright in methane band.  Oval BA has a pale orange color.  This can be confirmed on the blue channel where Oval BA is a little dark.  White Spot Z on the NEBn can be seen NW of the GRS. 

March 6, 2019
Condition was poor today.

The SEB is pale in this region while the NEB is dark.  Io is transiting on the NEB.

March 4, 2019
Condition was good today.

There a lot of details captured in these images.  The South Polar Red Spot is prominent and close to the CM on the first RGB image.   Oval BA is rising on the second image and it shows a light orange color.   The SEB is turbulent in this region.  THe NEB looks quiet in this region except of the area .

February 28, 2019
Seeing was variable today. 

The South Polar Red Spot can be seen in this image.  The SEB is light in this region.  The NEB is quiet and very dark.

February 27, 2019
Seeing was much better today.

The GRS can be seen setting on the far right.   The wake of the GRS is featured in these images. Note also the two small white ovals on the SSTB to the right of the CM. Will they merge? The EZ has reddish shade.

 

February 25, 2019
The past few days has been crazy.  The sky would be clear all day until around 4-6am which is prime time for Jupiter imaging!  The sky cleared early today at around 5am. 

Oval BA can be seen rising on the right.  Note that it has a pale orange color.  This spot was white a week ago.   In methane band, Oval BA is brightening again!  Will it turn red?  Coincidentally, yesterday was the 13th anniversary of the discovery of Oval BA turning red. 

The GRS can be seen peeking on the right of the IR image.   The SEB is a contrast of colors with the dark band on the SEBs and the pale mid-SEB.  The NEB is dark and narrow.

February 21, 2019
I finally got a decent image of Jupiter with the GRS!

The GRS is well resolved in these images.  Note the dark center core.   Following the GRS is what looks like an outbreak.  This feature is not very bright in methane band.  So this might not be the outbreak that will revive the SEB.   The dark band on the SEBn around the GRS looks veyr interesting.  Parts of the wake following the GRS is bright in methane band.

The White Spot Z can be seen north of the GRS.   In methane band, a slight brightening can be seen in the area of this feature.

February 19, 2019
The weather has been frustrating during the last week.  It is clear most of the day except for around dawn.  I was fortunate today that the sky cleared a few minutes before sunrise.  Seeing was still unstable.

The SEB is very pale while the EZ still has a strong ochre color.  The reddish band on the EZs can still be seen.   The is an outbreak on the NEB.

 

February 12, 2019
Condition was poor again today.  This was due to the N winds.

The NEB is quiet in this region.  The EZ has a strong ochre color with an amber tinge. 

February 11, 2019
Condition was very poor today. 

The GRS has a very strong color.  Oval BA is moving away from the GRS.  The southern edge of the SEB is very dark.

February 7, 2019
Condition was poor today.  The atmosphere was very unstable. 

Most of the SEB has become pale except for its southern edge and the mid-SEB.   Oval BA can be seen rising on the left in the methane band image.  The NEB is very dark in contrast to the SEB.

 

February 7, 2019
Condition was good today.  

SEB is fading.  The color of the SEB is very similar to the color of the EZ!    The SEBn is very dark.  There is a faint bluish feature on the STB.  Is the the STB Spectre or  Ghost?   This feature is dark in methane band.  There are some ovals visible on the SPR.  These are prominent in the IR image.

The EZ has a strong reddish haze.  The NEB is narrow with a lot of rifting.   Note the subtle reddish band on the NTB.

February 2, 2019
Condition was better today compared to yesterday but seeing was still a bit unstable.  Transparency was poor.

The GRS is setting on the right.  Note the reddish patch following the GRS.  This feature is bright in methane band.   The SEB is indeed fading!  The SEBn has basically lost color!  The EZ has a reddish hue.  The NEB looks quiet in this region.

 

February 1, 2019
We are currently experiencing the NE monsoon.  This brought a lot of cloudy skies here in our region.   It was clear this morning but seeing was poor due to the low altitude of Jupiter.

Oval BA can be seen rising on the lower left.  Oval BA is still bright in CH4.   Note the SEB seems to be fading!   Note the dark red barge on the mid SEB.   The EZ has a strong yellow color with a reddish band on the mid-EZ.  The EZ is very bright in CH4.  There is a bright outbreak on the NEB.

January 15, 2019
Condition was terrible today.  Transparency was poor because I had to image through clouds.  Seeing was also poor.

The mid-EZ seems to be forming a reddish belt.  I had observed this on my previous image but it is much clearer now.   The SEBs has a very dark.

 

January 6, 2019
 

Here is my first image of Jupiter for this season. Imaging was a bit challenging because Jupiter is so low in the sky, less than 25 deg! Seeing was terrible but I had to capture something.

The GRS and Oval BA can be seen on these images. The GRS still has very strong orange color. One thing interesting is that Oval BA looks WHITE! This is probably due to the quality of the image. In Methane Band, BA is not as bright as before. The entire EZ has a dark yellow color with the EZs having a reddish hue.

FYI, those who are using QHY series 3 cameras should update to the latest Windows 10 driver. I went crazy this morning when my laptop refuses to recognize my camera! Fortunately, the latest Win 10 driver fixed this problem.
