Bob Moler's Ephemeris Blog

Ephemeris for Wednesday, August 21st. Today the Sun will be up for 13 hours and 47 minutes, setting at 8:39, and it will rise tomorrow at 6:53. The Moon, 2 days before last quarter, will rise at 11:41 this evening.

Let’s look at the planets for this week. Mars and Venus are too close to the Sun to be seen. Mars is still on the evening or east side of the Sun, as is Venus which passed superior conjunction with the Sun a week ago. Bright Jupiter will be in the southern sky as it gets dark. With steadily held binoculars a few of the 4 largest satellites of Jupiter can be seen. Four of Jupiter’s largest satellites can be spotted in telescopes tonight. Jupiter will set at 1:04 a.m. Saturn, the ringed planet, will be in the southern sky in the evening. It will pass the meridian, due south at 10:45 p.m. and will set at 3:12 a.m. Mercury will rise at 5:44 a.m. in the east-northeast.

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