At yesterday's SAC meeting I mentioned that this is the season to watch 
Jupiter's moons occult and eclipse each other, since we're passing through the 
orbital plane near opposition.  The most favorable of these events involve 
Ganymede or Callisto being eclipsed, since they are larger than Io and Europa.  
Sky & Telescope's site has this article on the subject authored by Alan 


It mentions a table creation page, which I have found to be very accurate.  Use 
that table, and just enter 697 as the observatory code, which is accurate 
enough for all of Arizona.

The next good event is an eclipse of Callisto by Io on the 15th at 12:30UT 
(5:50 a.m.).  That "Impact" column is important; a smaller number means more 
coverage, with 0 being a central passage.
