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.

May 23, 2019
The sky was very hazy today.  Seeing was good but transparency was poor.

Oval BA is rising on the left.  Note the bluish features on the p side of Oval BA.   The SEBs show small ovals lining up.  The mid-SEB is very pale.  The EZ has a strong ochre color.  Io is on the NEBn with it's shadow preceding it.  Close to the south pole, there is a dark wavy dark line.

 

May 22, 2019
I overslept today and totally missed the GRS.  Condition was very good when I took these images.

Note the reddish haze spilling  over the mid-SEB.  THe NEB shows complex rifting.

May 21, 2019
We are having an early monsoon here.  Fortunately, the sky cleared this morning.  Seeing was variable but mostly excellent.  Transparency was poor due to haze.

Oval BA is still mostly white.   The wake of Oval BA is complex.  Above Oval BA is an interesting feature on the SEB.  The barge is surrounded by a bright haze.  The NEB looks quiet in this region.  Ganymede is approaching Jupiter and the south polar cap is resolved.  Some albedo features can also be seen.

May 17, 2019
We had rainy weather during the last few days.   The sky cleared today but dew was a challenge and I had to deal also with haze.

The GRS is well resolved in these images.  The left side the the GRS shows a reddish extension.   There is a bright outbreak on the wake of the GRS.  Note the oval inside the GRS!   Note the methane band bright feature on the p side of the GRS.

The NEB shows rifting.  It is dark and narrow.   The WSZ is still above the GRS.  Europa and it's shadow is transiting Jupiter.

May 13, 2019
Condition was perfect today.

Oval BA is rising on the left.   The South Polar Red Spot can also be seen just past the CM.  The SEB is mostly pale but very active in this region.   The NEB is dark but narrow.  Note the bright band in Methane Band above the NEB.

May 12, 2019
Seeing was perfect this morning but I had to deal with some periods of thin clouds.  These are my best images for the season.

The GRS and its surrounding region continue to be very active.  The GRS is well resolved and many features visible inside the GRS.  Note the large white oval just east of the GRS!  There is a bright outbreak on the wake of the GRS.    Note what looks like three white spot between the GRS and the outbreak.

The NEB is quiet in this region.  WSZ is not bright in methane band.

 

May 10, 2019
Condition was challenging today.  Seeing was only 7-8/10 and transparency was variable due to clouds.

The GRS is setting on these images.   The dark stream surrounding the GRS is still prominent.  The dark core of the GRS is well resolved.  The edge of the GRS is also dark.  Note the methane brights streak on the wake of the GRS.  Although the SEBn is turbulent and active, the mid-SEB is very pale!

The EZ still has the reddish haze.  The NEB is quiet in this region and the WSZ can be seen above the GRS.  Europa is at the edge of the NTB.

May 9, 2019
Condition was perfect today.

Oval BA is prominent in these images.  The orange ring on BA seems to be forming again.  The wake of Oval BA looks very turbulent.  Note the barge on the SEBn above Oval BA.   The NEB is dark.  Note the dark red spots on the NEBn.  The GRS is rising on the left.  On the methane band, note the bright extension on the p side of the GRS.

May 8, 2019
I just returned from my trip to Cartagena, Colombia.   Seeing was excellent last night but transparency was very poor due to clouds and haze.

Note the bluish feature on the STB.  It seems to be making a U turn. This feature is dark on IR.   Note the white spots on the southern edge of this feature.   The SEB is very pale.   The EZ still has the reddish haze.  There are a lot of details resolved in the Temperate zones.

April 17, 2019
Perfect conditions today!

A lot of details are resolved all over the planet.  Oval BA is pale.  The GRS is rising on the left.  Note the extension on the north side of the GRS.  This extension is bright in methane band.  The SEBn is turbulent.  The NEB is dark.  Note the reddish feature on the NEBn close to the CM.

April 16, 2019
Seeing was good today.

The SEB is very pale in this region.  The SPR red spot can be seen. The NEB has some complex rifts.  Note the methane band image shows a  bright streak on the NTrZ.  This seems to be associated with anticyclonic spots.

 

April 15, 2019
Seeing was fair today.  Transparency was variable due to dew.

The GRS is well resolved in these images.  The area surrounding the GRS is very chaotic.   The reddish outflow on the f side is gone.  But there seems to be some remnants on the wake.   Note the dark barge on the p side of the GRS.   The shape of the GRS in Methane band looks sharp on the p side.

White Spot Z can be seen above the GRS.  The NEB shows a lot of rifting.  Europa can be seen on the NNTZ.   Ganymede's shadow  can also be seen on the send RGB image on the upper left.

April 12, 2019
Came back from my trip to NEAF/NEAIC.   Seeing was fair today.

Oval BA is prominent on these images.   The inside of Oval BA is pale orange.   The SEBn is turbulent.  Note the dark barge NNE of Oval BA on the SEBs.  The EZ still has the reddish haze.   The NEB is quiet in this region.  It is dark and narrow.

March 31, 2019
Seeing was very variable today.   I had to throw in a lot of data to get a decent image.

The GRS is rising on the left.  Note the methane band image of the GRS looks very strange due to the bright extensions. Note also the bright bluish "tail" on the p side of the GRS.  The SEBs has a dark maroon color. Note that the small AWO south of the GRS has not merged! Oval BA is past the CM with a pale peach color.  The reddish smudge on the EZs has just past the GRS.

March 30, 2019
Seeing was variable this morning.

There is a very bright outbreak on the NEB!   This outbreak is very bright in methane band!  Note the TWO circular feature on the NEB at the CM of the first image. This is similar to the circular spot  Phil Miles and Anthony Wesley first noticed this a few days ago on another region of the planet.  The SEB is pale in this region.  NOte the small ovals lining up at the SEBs.

March 29, 2019
Transparency was poor this morning due to thin clouds.  Seeing was fair.

The GRS is well resolved in these images.  Note the red extension of the GRS on the f side which seems to be leaking into the SEB.  The wake of the GRS is very turbulent.  The shape of the GRS in Methane band shows the red extension.

Note the two tiny Anti-cyclonic White Ovals (AWO) below the GRS on the STB.  As Damian noted, these two seem to be close to merging.  Both of these AWO are bright in methane band.

The NEB looks quiet in this region.  Io can be seen on the NEBn.  Above Io is the White Oval Z.  There are a good number of small white ovals on the NNTZ.  Two small white ovals on the NNTZ seem to be right next to each other.  This can be seen on the 2nd color image just before the CM.

March 27, 2019
Condition was fair today but I had to deal with dew.

The GRS is setting on these images.  Note the dark material on the SEBs along the wake of the GRS.  The EZ still has the reddish haze.  Lots of rifts on the NEB.

March 25, 2019
Condition was close to perfect today.  I had a late start in imaging.  I only got one set of methane band before the sky was just to bright to image.

The SEB is very pale in this region.  Small ovals are lining up on the SEBs.  The dark area of the NEB is very thin in the methane band image.  Note the tadpole like feature on the NNTZ at the CM.

March 23, 2019
Condition was fair today.

The SEB looks quiet in this region.   There are dark ovals lining up on the SEBs/STrZs area.  The South Polar red spot can be seen. The NEB is dark.

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.
