Monday, November 14th.  The sun will rise at 7:37.  It’ll be up for 9 hours and 38 minutes, setting at 5:15.   The moon, half way from full to last quarter, will rise at 8:19 this evening.

The moon will be a waning gibbous phase tonight.  The terminator is now the sunset line sweeping slowly across the moon. To the unaided eye or binoculars darkness will be falling across the Sea of Tranquility on the moon’s equator and will start to cross the Sea of Serenity above it.  Below Tranquility is of my favorite craters Theophilus with its central peak will again stand out in shadows.  It won’t be very close to the terminator tonight, but by tomorrow night it will be in the moon’s night and gone from our sight.  The moon’s days and nights last nearly 15 days each.  We are lucky to have a large satellite orbiting the earth.  We may never know how important the role it had to play in establishing life on the earth.

* Times, as always are for the Traverse City/Interlochen area of Michigan.
