I hope some of you are having clear mornings because here it has been cloudy at 'comet' time. Send me some pictures please!!!! ;-)
For those of you wanting to calculate when to see the Great Red Spot and Red Spot Jr. there is a GRS calculator on the Sky and Tel website... http://skyandtelescope.com/observing/objects/planets/article_107_1.asp The GRS is currently around 104 d long and I believe around 20 d South so unless my upside-down thinking is off Junior should transit after GRS. (the image on Science@NASA being south-side up) without lats and long on both I can be exact with a calculation but with a 10hr rotational period you wouldn't have to wait very long maybe 2 hours would get both in the same frame??? Astrophotographers out there have any comments or corrections???
Cheers! Category:Tools
