Ephemeris for Wednesday, March 8th. The Sun will rise at 7:07. It’ll be up for 11 hours and 32 minutes, setting at 6:39. The Moon, 3 days past first quarter, will set at 5:24 tomorrow morning.
Let’s check out the bright planets for this week. Venus and Mars are in the evening sky. At 7:30 p.m. these planets will be seen in the western sky. Venus is unmistakable as the brilliant evening star, Mars will be left and above it and much dimmer. Venus exhibits a dazzling crescent in small telescopes and binoculars now. It looks like a tiny Cheshire Cat grin. Telescopes, however can turn that grin into a frown. It will set at 9:01 p.m. while Mars will set at 10:12. Jupiter will rise in the east at 9:22 p.m. It will also be seen in the morning in the southwest above the star Spica. Saturn can be glimpsed this and tomorrow mornings in the south-southeast before 6:30 a.m. It will rise tomorrow at 2:53 a.m. in the east-southeast.
Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
