08/07/2014 – Ephemeris – Two large craters of the lunar highlands visible tonight

August 7, 2014

Ephemeris for Thursday, August 7th.  The sun rises at 6:35.  It’ll be up for 14 hours and 24 minutes, setting at 8:59.   The moon, 3 days before full, will set at 4:07 tomorrow morning.

The gibbous Moon is getting brighter as it becomes more sunlit from the Earth’s prospective.  The disk of the Moon will be 89 percent illuminated by the sun tonight.  The bright crater Aristarchus, which I’ve talked about before, on the upper left of the moon is now in sunlight.  On the lower left there are two interesting craters for the small telescope.  Split in half by the sunrise line terminator is the large crater Schickard 137 miles  (227 km) in diameter.  Craters near the limb of the Moon are foreshortened by the fact that the Moon’s nearly spherical so they there appear elongated.  One, more elongated than most, is nearby Schiller which is actually 108 by 43 miles (179 by 69 km), which may be two overlapping craters or a really low angle asteroid impact.

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