Saturn dark spot & white spot May 20th

Hi All,

Imaged Saturn last night over a 2 hr session and have 5 "R", RGB & 807nm IR data sets.

I have been monitoring a dark spot on the edge of the great storm remnant and captured it in the first data set last night. Later in the night I also noticed an isolated white spot in the region of the recent SED's outburst.

Have attached the "R" & RGB that best show the dark spot which WinJUPOS puts at approx lat +43.4 L3 255.9.

The white spot is best seen in the RGB from 10:50 UTC where it is close to the CM, WinJUPOS puts it at approx lat +15.6 L3 336.2

Have also attached links to animations of all data sets. The dark spot comes up in both the "R" & RGB animations while the white spot appears to pop in and out of the RGB animation as it was only on the final 2 RGB's.

The 807nm IR animation is interesting as there is a dark spot within the great storm remnant that comes up nicely.

Thanks for looking.
