Ephemeris for Wednesday, July 16th.  Today the sun will be up for 15 hours and 11 minutes, setting at 9:24.   The moon, 2 days before last quarter, will rise at 11:52 this evening.  Tomorrow the sun will rise at 6:13.

It’s Wednesday and once again time to locate the bright planets for this week.  Reddish Mars is in Virgo in the southwest as darkness falls.  It’s 101 million miles (163 million km) away now, nearly 2 and a half times farther away than last April, and will set at 12:56 a.m.  Saturn will be low in the south-southwest as darkness falls, in the faint constellation of Libra the scales.  It will set at 2:06 a.m.  Saturn’s in perfect position for viewing with a small or large telescopes to see those fabulous rings and its large moon Titan.  Somewhat larger telescopes can spot some smaller moons closer in.  Brilliant Venus will rise in the east at 4:14 a.m. in morning twilight.  Mercury will rise at 4:46 and be barely visible below Venus.

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