Bob Moler's Ephemeris Blog

Ephemeris for Wednesday, May 24th.  Today the Sun will be up for 15 hours and 7 minutes, setting at 9:13, and it will rise tomorrow at 6:04.  The Moon, 1 day before new, will rise at 6:20 tomorrow morning.

Let’s take our weekly look at the bright planets.  Mars is still in the west-northwest after sunset and fading.  It appears near the left edge of the constellation Auriga.  It will set at 10:49 p.m.  Dominating the evening sky now is Jupiter in the south.  The bright blue-white star Spica is seen below and left of it.   In even the smallest telescopes Jupiter’s four largest moons can be seen.  They shift positions night from to night and sometimes even as you watch.  Jupiter will set at 4:09 a.m.  At 5 a.m. both Saturn and Venus will be in the morning twilight.  Saturn will be low in the south-southwest.  It will rise in the east-southeast at 10:45 p.m.  Brilliant Venus will be low in the east tomorrow morning after rising at 4:16 a.m.

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