01/17/2014 – Ephemeris – The Moon tonight

January 17, 2014

Ephemeris for Friday, January 17th.  The sun will rise at 8:14.  It’ll be up for 9 hours and 16 minutes, setting at 5:30.   The moon, 2 days past full, will rise at 7:23 this evening.  |  Let’s take a look at the moon as it’s still dominates the evening sky.  The terminator, now that it’s after full moon is the sunset line.  It is just starting to encroach on the small distinctive sea at the moon’s upper right edge called the Sea of Crises or Mare Crisium.  Where is is situated on the edge of the spherical moon it appears to be elongated north to south.  However if you saw it from overhead it would actually be elongated somewhat east to west.  On the terminator at the moon’s equator is a large crater called Langrenus with a central peak on the edge of the Sea of Fertility or Mare Fecunditatis, that should be an easy binocular and a great telescopic crater some 80 miles in diameter.  The smallest ting you can see on the moon in a small telescope is 2 miles in diameter.

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