[AZ-Observing] Re: Jupiter Events


I probably should have left my 10-inch to equilibrate earlier, 
but at both 400x and 560x, Callisto is a dark featureless 
spot--not unlike a shadow--and Io is a pale spot just about to 
cross the central meridian at 7:50pm.  There is a festoon north 
of Callisto which may effect Io's visibility, as they appear 
close to same albedo--I think Io may be darker, though.
