Bob Moler's Ephemeris Blog

Ephemeris for Tuesday, May 29th.  Today the sun will be up for 15 hours and 16 minutes, setting at 9:18.   The moon, 1 day past first quarter, will set at 2:38 tomorrow morning.  Tomorrow the sun will rise at 6:01.

The moon tonight is a wonderful sight for binoculars or a small telescope.  There are some very nice craters now revealed near the terminator, the line between day and night on the moon.  The terminator in the two weeks between new and full is the sunrise line on the moon.  From the top or north on the moon is the flat floored crater Plato Then about midway down the moon and right on the terminator is the beautiful crater Copernicus.  Then to the south end of the moon is the bright and crisp crater Tycho.  Its splash marks called rays will be better revealed at full moon.  At the bottom of the moon, just coming into light is the huge crater Clavius.  A telescope will reveal smaller craters within.

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