09/12/2013 – Ephemeris – A look at the first quarter moon

September 12, 2013

Ephemeris for Thursday, September 12th.  The sun will rise at 7:18.  It’ll be up for 12 hours and 40 minutes, setting at 7:58.   The moon, at first quarter today, will set at 12:36 tomorrow morning.

By this evening the moon will be just past first quarter and the terminator will bulge a bit to the east.  Through binoculars or the naked eye the scallop shell shaped sea will be visible at the upper right part of the moon,  the man in the moon’s left eye.  In telescopes the moon will be inverted and even also reversed, so Serenity could appear in any other quadrant depending on what your telescope does to the image.  Toward the terminator from Serenity  are two mountain ranges The south part is the Apennines, and the northern part is the Alps.  The Alps is cut by a gash called the Alpine Valley.  There’s also a triangle of distinctive craters also visible near the terminator.

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