February 28, 2014

It was a bit windy this evening.   This affected the image quality as vibration was very bad with my mount.

Oval BA can be seen setting on the first image.  The SEB looks very complex with a lot of dark ovals on the SEBs/STrZ.  The NEB looks very narrow.  

February 26, 2014

Seeing was excellent this evening.  I was able to image after the sky cleared.  It was very cloudy earlier this evening.

The NNTZ LRS is prominent in these images.  It has a strong red color with a hint of the white center.  It is currently surrounded by some dark clouds.

The Red Spot Z still has the reddish color but it is still very pale.  This spot is very bright in Methane band and dark in UV.

The SEB is very complex.  Note the bluish streak on the STB.  Note also the little dark spots on the STrZ.

February 25, 2014

Condition was excellent this evening.

Oval BA is slowly approaching the GRS.   The wake of the GRS is very complex.  volcanic Io is well resolved on the SEB.   There is a bright rift on the NEB.

February 24, 2014

I had a very frustrating evening.  It was clear all day today but at around the prime time to image Jupiter, clouds started to roll in.  I had to image during breaks in the clouds.  The first two color images are single RGBs while the last two are derotated.

The Red Spot Z continues to have a faint reddish color.   What is interesting is the NTB outbreak.  It is not as bright as last week.  One thing interesting is that this feature doesn't show up in CH4!  In fact some areas of this feature is DARK in CH4.

The bright feature in the SEB preceding the GRS is very prominent.  The GRS  had  a strong reddish color.  The STrZ around the GRS has some light orange coloring.  Note the bright feature next to the bluish cloud on the STrZ preceding the GRS.

The NEB is dark and narrow with a lot of rifts.

Today is the 8th anniversary of my discovery of the Red Oval BA!

February 23, 2014

I'm back from my short trip to Manila.  Seeing was good this evening but transparency was variable because of moving clouds.  This made imaging a bit frustrating!

The Red Oval BA can be seen just past the CM.  The center of oval BA is still white.  The color is a bit pale.   Tomorrow is the 8th anniversary of my discovery of this red spot!

The large dark shadow is that of Ganymede.  The SEB looks complex.   There are outbreaks erupting in the NEB.

February 19, 2014

Looking at the images tonight, one might think that I had perfect conditions.  However, conditions were far from perfect.  Transparency was very poor because of thin clouds despite the excellent seeing conditions!  I could only use less than half my usual the frame rate with full gain!  This is derotation to the rescue!  I just double my usual RGB sequence I take and derotated all these images!   Individually, each image is very grainy but after derotation, I got these excellent images!

The Red Spot Z can be seen close to the CM.  The  new red spot still has a faint red color.  The NNTZ LRS can be seen in the north.  The GRS is rising on the left.  Note the light feature on the SEB seem to be approaching the GRS!  I  wonder what this feature is....  There are some activity on the NTBn.

Unfortunately, I couldn't do any CH4 or UV images because of poor transparency.

I'm leaving for Manila tomorrow to give two workshops on Planetary imaging.  Hope to be back imaging on Saturday.

THE SECOND ROUND:

After processing my first set of images, I went out and saw Jupiter out of  the clouds!  I couldn't resist going on a second round with the GRS at the CM. Transparency was a little better that earlier but it still wasn't great while seeing was excellent!

The GRS is at the CM!  Note the white spot at the 2 o clock position of the GRS! The GRS is well resolved. Note the dark core and some hint of the vortex arms.  The wake of the GRS is complex with some outbreaks close by. The STrZ has a yellowish tinge.  The STrZ around the GRS also looks a bit disturbed. 

The NEB is dark and narrow.  Some outbreaks can be seen.   Note the bright spots congregating on the NTB!   Is this outbreak similar to the powerful outbreak in 2007?

February 18, 2014

I had a late imaging session this evening because we had a stargazing session at USC.   This area is close to the area I imaged 2 days ago. 

Note the NEB outbreak which seems isn't as active compared to two days ago.  The SEB continues to be very complex.

February 16, 2014

Seeing was excellent this evening but I had to deal with intermittent clouds.

The SEB looks complex.  Note the dark barges on the SEBs.  There is a bright outbreak on the NEBs/EZ which seem to be associated with a festoon.  This outbreak is bright in UV and Methane Band.

 

February 15, 2014

It was clear today.  Seeing was a little unstable because of the strong winds. 

The GRS is setting on these images.  Note the very bright outbreak following the GRS.  This feature is very bright both in CH4 and UV!  The wake of the GRS is very complex.  Note the dark spots on the STrZ which seem to be coming from the GRS.  The NEB is quiet in this region.

February 14, 2014

I wasn't expecting any images today.  It was totally overcast!  At around 9pm, there was a small break in the clouds in the area of Jupiter.  Just  went ahead  and took an image.  I was only able to capture some RGB sequence.  Seeing was excellent despite the poor transparency.

Here are 3 red spots of Valentine's day!  The GRS  is rising on the left,  the reddish Red Spot Z is past the CM and the NNTZ LRS is setting on the upper right. The area preceding the GRS has some complex activity.

Two dark barges are still following the NNTZ LRS.    The area of the NTB below the left barge is interesting.

 

February 10, 2014

It was mostly cloudy today.  I  had a short break on Jupiter.    Seeing was excellent.  Unfortunately, the sky became overcast and I was unable to capture  with Methane Band and UV.

This is my first decent capture of the Great Red Spot (GRS). The region around the GRS is very busy and complex.   The halo of the GRS has a yellowish color. Note that the STrZ has a yellowish/orange tinge.  The GRS is resolved.  Note the dark center and hint of the vortex arms.   Reddish material seem to spilling over from the GRS to both sides of the STrZ.

The NEB looks dark and narrow. 

February 9, 2014

I did not expect to get an image this evening.  It was cloudy most of the day and forecast was rain!  But the sky cleared at  around 9pm local time so I was able to grab some images.  Seeing was okay.

Io can be seen transiting Jupiter's SEB.    The three red spots are visible.  The GRS is rising on the southwest.  The new Red Spot Z is at the CM.  RSZ has a pale reddish color.   The NNTZ LRS is prominent. Note the dark red barges to it's south.

February 6, 2014

Had bad lack yesterday when it was cloudy.  Missed imaging the GRS.  I had to image a little late today because I had some kids who wanted to use the telescope .  These were 3 year old triplets, sons of  a family friend who were very interested in astronomy.  They even work astronaut costumes when they came...  Seeing was excellent today.

Caught a double shadow transit this evening.  The small shadow is Europa's shadow while the bigger one is Callisto's.  Note Callisto's shadow shows both the Umbra and Penumbra. The Red Oval BA has a pale orange color and is between the two shadows.   The SEB is vey complex.  The NEB is quiet in this region.  Note the triple white spots on the NTBn close to the CM.

 

February 4, 2014

Seeing was excellent this evening! 

This is the area preceding the GRS. The SEB looks very complex.  The NEB is also very active.  The NNTZ LRS can be seen rising on the left.

 

 

February 3, 2014

I had imaged earlier this evening.  Unfortunately, seeing was so bad that after initial processing, I gave up and retook more images.  Seeing was excellent this evening.

The wake of the GRS is very complex.  Oval BA has pale orange color.  The NEB is very complex.  The SPR red spot can also be seen.

 

February 2, 2014

I had a crazy evening.  I finally figured out how to make the Flexi Dew Shield of my C14 stay put!  But while trying to install it, I somehow hit my Bob's knobs and to my horror, collimation  was now way off!  I had to spend almost an hour recollimating my OTA.  Dew was still a problem but the dew shield really helped!   Seeing was excellent.   After imaging, I spent some time doing a visual observation on the M82 supernova which is still very bright!

Io shadow is moving out of Jupiter.  The SEB is very dark in this area preceding the  GRS.

Jupiter's new red spot the Red Spot  Z is still very pale in color.  But this spot has become very bright in Methane band even brighter than the NNTZ LRS.  The NEB is very active with a lot of outbreaks.  The NTB has some complex activity.

The NNTZ LRS is still red while the deep red feature to it's south has broken up.

February 1, 2014

We had a powerful tropical storm this morning.  Fortunately, no serious damage here in Cebu.  The tropical storm seemed to have wiped away all our bad seeing here.   Seeing was incredible this evening.  Unfortunately,  I had to deal with dew which was a  bit frustrating at times!

The Red Oval BA is prominent in these images.    Note the dark thick ring around Oval BA and it's complex wake.  Note also the dark line of dark materials that is coming from the GRS going to Oval BA. The SEB shows the wake of the GRS.

There are some outbreaks in the NEB.  The NEB is still dark red. The NTB looks quiet.    White spots can be seen up to both polar regions including the reddish spot on the SPR.

January 29, 2014

Seeing was still bad lately.  I was able to scrape some acceptable images.

Oval BA is now approaching the GRS!!  Conjunction should happen in the coming months.  Note the chaotic wake of the GRS.  The "Mickey"  SSTB ovals are still prominent.  The NEB  is dark and narrow with a lot of complex rifts.  The NTB looks quiet in this region. 

 

January 24, 2014

Seeing was still unstable this evening.  Did a stupid thing!  I deleted my data this evening.  Unfortunately, my had set my Recycle Bin to a low number.  I lost a lot of my data!

The GRS is prominent in this image. Note that the area  of the SEB preceding the GRS looks very red.  The wake is very complex.  The NEB is very dark.

 

January 22, 2014

We had a long lingering Low Pressure system and a cold front which gave us cold, cloudy and wet weather!  Seeing was terrible this evening and it was also very windy. 

Oval BA is rising on the left.  The SEB is dark in IR.  This is the area of the wake of the GRS.

January 4, 2014

Happy New Year!!  This is my first image this year and a few hours before Jupiter Opposition!  Seeing was unstable and I had to stop because of clouds.

The GRS is very prominent rising on the left.  Note the chaotic area preceding the GRS.  Note the bluish feature interacting with the reddish outflow that seems to be emanating from the GRS pushing it's way to the STrZ.

The NEB is very active with rift activity.  The Red Oval Z still retains its faint reddish coloration.  ROZ is very bright in CH4!  Much brighter than the NNTZ LRS!

The NTB looks very active!  Note the White Anticyclonic Oval seem to be squashed as it approaches the cyclonic feature just south of it!  Note the complex wake of this interaction.  The NNTZ LRS is very prominent.  Note the deep red barge just south of this red oval.
