Saturn Feb 24th in good seeing.

Hi All,

I have some interesting data from this morning. Imaged over a 2 hr session in pretty consistent conditions.

Image the section of the storm just back from the head to check up on the large dark spot that I imaged Feb 16th.
The morphology of this spot has changed, it is still quite prominent but clearly it has become more elongated. The structure, regarding the line of white spots in this region seems very similar to Feb 16th.

I have 5 RGB 807nm IR data sets which I have attached along with animations of both data sets. It is interesting to compare the animations with those from Feb 16th as the conditions were similar so I have also attached a link to that thread.

There was also a shadow transit of Tethys toward the end of the session which shows up in both RGB & 807nm IR data.

Thanks for looking.


Regards
Trevor
