May 12, 2016 Comments off

Ephemeris for Thursday, May 12th.  Today the Sun will be up for 14 hours and 44 minutes, setting at 9:01.   The Moon, 1 day before first quarter, will set at 2:26 tomorrow morning.  Tomorrow the Sun will rise at 6:16.

The moon tonight is a fat crescent.  In binoculars the small Sea of Crises is prominently located as a gray patch at the edge of the moon.  The Sea of Fertility is below it, while the sea of Tranquility is between them and near the terminator, the sunrise line on the moon.  In telescopes there are three craters south of Tranquility, most prominent of which is Theophilus. With its prominent central peak.  Farther to the north of Crises and near the partially exposed Sea of Serenity is the crater Posidonius, larger than Theophilus, but has a double crater wall on one side.  Larger telescopes can see cracks in its floor .  It has no central peak, and shows its age of maybe three and a half billion years.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
