03/11/2014 – Ephemeris – Observing the moon tonight: Bay of Rainbows and more

March 11, 2014

Ephemeris for Tuesday, March 11th.  The sun will rise at 8:02.  It’ll be up for 11 hours and 41 minutes, setting at 7:43.   The moon, 4 days past first quarter, will set at 5:39 tomorrow morning.

The moon tonight is a pretty fat gibbous shape, with the sunrise line or terminator revealing the Bay of Rainbows, Sinus Iridium, that large half crater at the moon’s upper left edge, and the edge of the Sea of Showers, Mare Imbrium.  In the figure of the man in the moon Imbrium is his big eye, kind of like the cartoon “Bill the Cat”.  To the right of it, looking like a hole in a mountain chain, is Plato, whose dark floor is unmistakable even at full moon, when shadows are absent.  The crater Copernicus is now beginning to be washed out as the morning shadows shrink.  To the left of Copernicus, just catching the sun’s rays on the terminator, is the smaller crater Kepler.  When the moon is full Kepler will show a fine ray system.

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

Addendum

Note for those not in the Eastern Daylight time zone.  10 p.m. is 2 hours March 12, 2014. If viewing before that time the terminator will be shifted to the right.  After the terminator will be shifted to the left.
