Ephemeris for Wednesday, September 22nd.*  The sun will rise at 7:29.  It’ll be up for 12 hours and 10 minutes, setting at 7:39.   The moon, 1 day before full, will set at 7:51 tomorrow morning.  |  Lets take a look at the bright planets for this week. Venus and Mars are very low in the twilight.  Venus is the brightest.  It’s 40.3 million miles away and slowly approaching, and appears as a thin crescent.  It will set at 8:34 p.m. Mars is right and above Venus, and much dimmer.  I doubt if you could spot it.  The planet Jupiter is up at sunset and will move due south at 1:30 a.m..  It’s located in Pisces this year.  Mercury is visible low in the east before sunrise.  It will rise tomorrow morning at 5:53 a.m.  Mercury is visible in the morning twilight in the east.  6:30 to 7 a.m. is the best time to spot it.  Tonight at 11:09 p.m.  the sun will cross the celestial equator heading south.  For us in the northern hemisphere autumn will begin.
