09/20/2017 – Ephemeris – Looking for the bright planets

September 20, 2017 Comments off

Ephemeris for Wednesday, September 20th. The Sun will rise at 7:27. It’ll be up for 12 hours and 15 minutes, setting at 7:43. The Moon is new today, and won’t be visible.

Let’s take our weekly look at the bright planets. Jupiter is really low in the west-southwest after sunset setting in twilight at 8:47 p.m. Saturn can be seen low in the southwest tonight. The reddish star Antares is below and right of Saturn before it sets at 10:18 p.m. Saturn’s rings are spectacular in telescopes. With the demise of the Cassini spacecraft orbiting Saturn for the last 13 years, there is no telescope closer to Saturn than yours. The planet will set at 11:35 p.m. In the morning sky, brilliant Venus will rise at 5:03 a.m. in the east-northeast. The first magnitude star Regulus in Leo the lion will be to the upper right of it. Dim Mars will rise in the east-northeast at 5:50 a.m. followed by the brighter Mercury which will rise at 6:12 a.m.

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