12/28/2016 – Ephemeris – Our last weekly look at the bright planets for 2016

December 28, 2016

Ephemeris for Wednesday, December 28th.  The Sun will rise at 8:19.  It’ll be up for 8 hours and 50 minutes, setting at 5:09.  The Moon, 1 day before new, will rise at 8:16 tomorrow morning.

Let’s take our last look at the bright planets for 2016.  In the southeast to south before 7:30 these mornings. Jupiter can be glimpsed as the sky brightens.  Jupiter will rise tomorrow at 1:53 a.m.  Venus and Mars are in the evening sky. At 6:30 p.m. these planets will be seen in the southwestern sky.  Venus is unmistakable as the brilliant evening star,  Mars will be above and left of it and much dimmer.  Venus will set at 9:01 p.m.  Mars will set at 10:12.  Mars’ setting time hasn’t changed much in the last 2 months.  Venus is slowly heading northward for the rest of it’s evening appearance, and is moving higher in the sky, and is closing in on it’s greatest eastern elongation from the Sun.

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

    Do you still post a monthly calendar? My husband has me print off a copy for him each year. He still listens to the program each morning, but he likes something to refer back to.
