The GRS is approaching Jupiter’s central meridian.

I observed the first part of the transit using the Naylor Observatory's 17" f/15 classical Cassegrain.  The conditions were not the best.  There were thin clouds and the seeing was poor.  I stopped down the scope to 14 inches and then 12 inches and employed a 2" light blue color filter to enhance the GRS.  Magnifications used were 116 (56mm Meade Series 4000 "Super" Plössl), 170 (38mm Agena SWA), and 185x (35mm Explore Scientific 70-degree), with the best views of the GRS occurring at 170x.

Observed with a near 50 year old C8. Seeing was mixed, average(poor) to good at best. When good, many details popped out. The GSR became separated from its cloud band and a few barges appeared. Overall I was pleased to have spent the time as the weather has been sooooo poor. Hit Saturn as well, same conditions. Warm cream color with a tan belt and darkening towards the pole. Cassini’s decision stood out and when conditions improved the “C” band was easily seen against it face. Best magnification was 170x. Over was a waste of time. Best seeing conditions were fleeting. Again, happy to have spent the time! Clear and steady skies.....

The GRS will transit Jupiter's CM at 6:31 UT (2:31 a.m. EDT) on Monday morning.
