I have been really hoping to catch the GRS. That will be 1:24 am Sunday morning here in Arizona and will be well positioned at 36 degrees above the horizon.
Looks like I might finally get my chance!

I sometimes use a Wratten #80A blue filter to enhance the GRS.
Good luck, Scott, and thank you for the heads up on the incorrect date.

Unfortunately, is is the monsoon season here in Arizona and of course it clouded up with thunderstorms overnight. So I missed Jupiter.
However, it did clear up before dawn so I was able to catch Mercury in my binoculars, So not all was lost!

I just happened upon the GRS placement this morning. Dead center on Jupiter when I sat down at my acclimated scope. Dumb luck.
I had mediocre seeing and things only popped a dozen times in an hour-long session with a 4" refractor. The Spot just keeps getting blander, year after year. The detail in the NEB was far more interesting, though that dark, thin band on the southern edge of the SEB had some visible swirls and knots along it's edges. The GRS looked like a pale lump in a snake that swallowed an egg. But all in all, the NEB had better contrast with it's darker features.
Good stuff, Dave. Keep the notices coming! (Even if I tend to see them all after the fact.)
