07/15/2016 – Ephemeris – The Moon tonight

July 15, 2016 Comments off

Ephemeris for Friday, July 15th.  Today the Sun will be up for 15 hours and 13 minutes, setting at 9:25, and it will rise tomorrow at 6:12.  The Moon, half way from first quarter to full, will set at 3:35 tomorrow morning.

The Moon is bright as it moves toward full.  In binoculars, the brightest spot on the Moon is visible on the left edge of the Moon at 10 p.m.  In telescopes it becomes a crater named Aristarchus.  The sea below Aristarchus where the terminator, the sunrise line cuts across is Oceanus Procellarum, the Ocean of Storms.  Below that is the small circular sea called Mare Humorum, the Sea of Moisture.  North of Humorum is a large crater with low walls and a multiple central peak called Gassendi.  Below that we’re back in the lunar highlands with lots of large craters.  One of those craters, near the terminator is oddly elongated.  It’s Schiller, 108 by 43 miles (174 X 69 km) in size.

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