Thursday, July 14th.  Today the sun will be up for 15 hours and 15 minutes, setting at 9:25.   The moon, 1 day before full, will set at 6:37 tomorrow morning.  Tomorrow the sun will rise at 6:11.

Jupiter has retained its title as the planet with the most satellites with the discovery last year of two new moons.  These tiny moons are just a couple of miles in size.  They were reported last year but were brought to my attention by a blog entry by Kelly Beatty of Sky and Telescope magazine, who spotted it among last year’s issues of the Central Bureau for Astronomical Telegrams.  They’re no longer telegrams but emails,but the name hasn’t changed.  Anyway he notes back in the day the announcement of a new satellite was a big deal, But now the announcement of Jupiter’s 64th and 65th moon is no big deal.  If you’re keeping count Saturn’s moon count is 62, three behind Jupiter, and we still haven’t found them all.
