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 MacRobert. http://www.skyandtelescope.com/sky-and-telescope-magazine/beyond-the-printed-page/mutual-events-jupiters-satellites-201415/ 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. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
