11/10/16 – Ephemeris – Sunrise on Aristarchus

November 10, 2016

Ephemeris for Thursday, November 10th.  The Sun will rise at 7:33.  It’ll be up for 9 hours and 45 minutes, setting at 5:19.  The Moon, 3 days past first quarter, will set at 3:35 tomorrow morning.

Tuesday I discussed the fact that the Moon appears to rock back and forth over the month due to it’s uneven motion around the Earth.  Currently it’s still facing the direction of the Sun by nearly as far as it was on Tuesday, which is revealing a crater on the northeastern side of the Moon about a day earlier than average in the lunar monthly cycle.  That crater is the brightest spot on the Moon, though it’s not that bright right now because that crater, called Aristarchus, is filled with shadow.  That shadow will go away in a day or two.  Aristarchus is visible in binoculars at the terminator, the advancing sunrise line on the Moon.  Aristarchus is located on the flat lava plains that early telescopic astronomers thought were seas filled with water.

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