Ephemeris for Wednesday, October 17th.  The sun will rise at 8:00.  It’ll be up for 10 hours and 52 minutes, setting at 6:53.   The moon, 2 days past new, will set at 8:21 this evening.

Let’s see how many bright planets we can find this week.  At 8 p.m. Mars can be seen low in the southwest approaching another red star Antares, whose name means rival of Mars.  They will be closest in a few days. The moon will be nearby too.  Mars will set at 8:45.  The planetary action moves to later in the evening and the morning. Jupiter, will rise at 9:17 p.m. in the east northeast.  It is located in the constellation of Taurus.  It will transit or pass due south at 4:52 a.m.  The last bright planet of the night is the morning star Venus which will rise at 4:44 a.m. also in the east.  Venus is now below the hind end of Leo.  The planets Venus and Jupiter and the winter constellations are a great sight for early risers.  You can enjoy for a few more weeks without danger of frost bite.

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