SATURN 2010-2011

Saturn has returned with a lot of excitement this season.  A new strong Electrostatic Disturbance has been observed in the northern hemisphere!

These  images are north up and were taken by my C11 mounted on an AP900GTO mount  with a Flea3 camera.

You can also see my past images of Saturn at the ALPO Japan Kansai Branch site.

June 4, 2011

Seeing and Transparency wasn't stable this evening.

This is the boring side of Saturn.  The "tail" of the NED can be seen.  The NEB is wide and very red.   Nothing interesting happening at the southern hemisphere.


May 30, 2011

Seeing was very variable and transparency was poor.

The NED is still very complex.  The head of the NED can be seen setting on the right.   There are a lot of bright spots on the northern edge of the NED wake. 

May 21, 2011

Seeing and transparency was just okay this evening. 

The NED is quite prominent.  Note that the head of the NED is interacting with material on the old tail!  The region around the NED has become very complex.

The NEB is very dark and wide.

May 13, 2011

Seeing was  unstable this evening. 

The NED is very prominent in these images.  The NEB is dark and broad. 


May 12, 2011

Seeing was good this evening.   It's been a while since my last image because I went on a trip to China to visit my grandfather's home town.

The NED is still spectacular!   The old and new material uplifted by the NED are interacting forming bright and complex features.  The head of the NED is still very bright.

Note that in the animation below, spokes can be seen on the left side of the B ring.  Please click the gif animation below to download the wmv video format of this animation.


April 28, 2011

Seeing was good but I was only able to scrape one image before clouds rolled in.

The remnant of the NED can be seen.  It is bright in the north and southern edge while dark in the middle.  Dark red streaks on the NEB are prominent.


April 26, 2011

Seeing was good last night but transparency was very variable.

The  head of the NED is very  bright!    Note the bright streak north of the NED.  The NED is interacting with it's own tail!  It is really amazing how powerful this storm is even until now!


April 25, 2011

Seeing and transparency was perfect this evening!

The extent of the NED can be seen in this image.  The head of the NED is rising on the left on the last image.  The tail of the NED is very chaotic with the old and new material interacting.

Note the spokes visible on the B ring on the left!  It is a dark  spot the moves around the ring.  This spoke seem to be moving with the head of the NED!


April 22, 2011

Condition was very variable today. I had to image early while Saturn is low to catch the NED.  Seeing was poor during the start of the session but improved as Saturn got higher.  Transparency was variable due to haze.

The NED is still going strong!  It's fascinating to see the head of the NED surrounded by the tail end it made 3 months ago. 


April 16, 2011

It was hazy and cloudy this evening.  I was able to get some images but transparency wasn't great.  Seeing was however good.

The NED wake is very prominent.  Note that the NEB is getting read the broad.   The belt north of the NED is also getting read.  Is this reddening an effect of the NED?

Saturn's rings are fading from the Seeliger effect a few weeks ago!


April 13, 2011

It was mostly cloudy this evening. But the sky cleared around 9:30pm. Condition was good.

The NED is still going very strong after basically going around the planet.  It's back to around CM3:240.  This is the area where it first appeared last December!  Wake material of the NED can be seem to the north and south of the NED.


April 11, 2011

Condition was excellent this evening.

This area is the wake of the NED.  It is still bright and complex.   The rings are slowly fading. 


April 9, 2011

The sky was overcast early this evening.  I thought the situation was hopeless but the sky cleared up around 10:30pm. After taking a few images, clouds started rolling in again only to clear after half an hour.  Seeing was excellent with perfect transparency. 

The NED is still very prominent.  Note the dark and white ovals lining up south of the NED outbreak area.  A bright belt has formed north of the NED.  The NEB is very dark red and wide.  The ring is still very bright.  The north polar area is very dark.


April 8, 2011

Seeing was again variable this evening.   But there were moments of good seeing.

The NED Wake looks very complex.  The red NEB is very wide.  It is also interesting to see bands on the north polar area.

Note the animation below which show the complex NED wake and a spoke moving through the B ring on the left.

April 7, 2011

Seeing was variable this evening.   I had to cut short my imaging run when clouds rolled in.

This is the area which features the tail of the NED.  This tail end is very complex.  The rings are still very bright!


April 5, 2011

Condition was better this evening compared to last night. 

The NED is still very prominent.   Note the difference between yesterday's shape of the NED and today's image.   There seems to be some "spoke" features on the ring. 

Check out the animation below.  Note the dark spot moving on the B ring on the left.  Is this a spoke or a shadow?


April 4, 2011

Transparency was poor this evening and seeing was very variable.

The NED continues to put on a strong  show!   I has almost gone around the planet!  The wake of this storm is very complex. The rings are still very  bright the day after opposition. 


April 1, 2011

Transparency was poor this evening.    Seeing was very variable.

The rings are very bright now reducing the contrast of the disk.  It's 2 days before opposition.


March 30, 2011

Imaging was frustrating this evening.  When I was setting up my system, the sky was clear.  The clouds started to roll in and I had to image between clouds.  Seeing was okay.

We are getting closer to the head of the NED.  But the wake of the NED is still very complex.  The contrast isn't as good now with the rings so bright due to the Seeliger effect.  It's only a few days to go before opposition!


March 29, 2011

Seeing wasn't great today.  I was only able to catch of few images before clouds rolled in.

The contrast on Saturn's disk has dropped considerably.   The tail end of the  NED is can be seen but it's contrast is not as high.  This is probably the result of the Seeliger effect.


March 28, 2011

It had been cloudy during the past weeks.  Condition was good this evening.

It is interesting to see that the Seeliger Effect is now visible!  Saturn is just a few days from opposition.  The ring is very bright because of this effect.

There are some details in the area of the NED.   Rhea can be seen on the lower left.


March 5, 2011

Condition was frustrating this evening.  I had to play peekaboo with a patch of cloud that is in the area of Saturn.  Seeing and transparency was very variable.

This is the tail of the NED.  Note the dark patch  on the tail.   The NED tail is still very  complex. 


March 2, 2011

Seeing was excellent this evening.  I finally had clear skies after weeks of rain!

The NED is still going strong!  The head of this storm is at ~CM3: 120! Note the feature south of the wake of the NED.

The C ring is can be seen.  The Cassini division is distinct around the planet.


February 16, 2011

Seeing and transparency was poor this evening. 

The NED is very prominent and bright. 


February 11, 2011

Seeing was excellent this evening. 

This is the region where the NED started.  It is interesting to note that even though the head of the NED is on the other side of the planet, this area is still bright.  The NED has basically moved more than half the  planet now.

The SEB can be seen just below the ring. 


February 9, 2011

Seeing was good this evening but not as good as yesterday. 

Here's another view of the NED.  Note the change in the structure of the NED barely 22 hours after my image yesterday.  The bright spot on the NEB is still very prominent.

February 8, 2011

Seeing was excellent this evening with Saturn close to the meridian.  But transparency was poor.

It's amazing that the change of the NED just a few days ago is very obvious.  On Feb 5, the wake was very plain while know it's knotty!  Note the bright feature south of the NED.  Is this another disturbance?

The C ring can be seen in these images.  There is even a hint of the Encke Minima.


February 5, 2011

After weeks and weeks of rain, I finally had clear skies!  Seeing was excellent.

I was able to catch the NED!  The NED now looks like a comet.  It is very bright and prominent.  I spent a few minutes observing it visually and it is very distinct bright white feature in Saturn's northern hemisphere.  The NEB is red and distinct now.   The Cassini division is very distinct.

Check out the animation below.

January 14, 2011

It  was again mostly cloudy this morning.  Transparency was very poor but I was able to get a break for a few minutes.  Seeing was average.

The NED is really grown and it's affected area has covered almost half the planet.    Contrast on this image is still poor because of poor transparency.


December 13, 2010

Seeing was good this morning.  I had an early start with Saturn because of the alert by Georg Fisher of the Cassini RPWS team that the Electrostatic Disturbance is back.  Images by other amateurs show that the disturbance is now in the northern hemisphere instead of the southern hemisphere in the past years.  Saturn was 48 deg above the horizon when I took this image.  This is the first time I imaged Saturn with my Flea3 camera.  The faster frame rate and extrra sensitivity really helped in making this image look good.

In my image this morning, the Northern Electrostatic Disturbance (NED) is very bright!  I was even able to see it distinctly visually!  The position of the storm has shifted  from it's original III: 250 to around III: 261!!!  Note the "tail" like feature of this storm.

The Cassini Division is very distinct.
