I haven't seen such a peculiar feature on Jupiter since the Schoemaker-Levy impacts. It was a large dark "comma"-shaped feature. At times I suspected the GRS was hiding under it, but the conditions weren't good enough to be sure.

Recently dark material has been seen winding round the spot and it seems to be changing frequently. well done on capturing this feature! along with a wealth of banding...

I missed Jupiter today as I got home too late. Did anybody else get a look at it?

That makes the sketch golden. I'm planning to go out shortly to take a look at the King and the GRS should be visible. Unfortunately, the CSC has changed its forecast--the seeing is now supposed to be poor so I don't know what I'll be able to detect. I'll report back here.

Re: A most peculiar Jupiter (16 Feb. 2011) [Re: Special Ed]       #4394136 - 02/18/11 03:25 AM Attachment (20 downloads) Edit   Reply   Quote Quick Reply   Mark, An excellent observation of Jupiter. You have captured fine detail across the Jovian disk. You actually recorded the re-emergence of the Red Spot Hollow (RSH, also known as the White Spot Hollow (WSH)) which normally borders and nearly encloses the Great Red Spot (GRS) towards the north. I have attached an excellent image of Jupiter obtained by Glenn Jolly of Arizona that shows the GRS/RSH very nicely. Thank you for sharing it with us all.

Thanks for posting the image, Carlos. I saw something similar in the Solar System Imaging forum recently.
