Ephemeris for Wednesday, December 27th. The Sun will rise at 8:18. It’ll be up for 8 hours and 50 minutes, setting at 5:08. The Moon, 1 day past first quarter, will set at 2:43 tomorrow morning.

Let’s take our weekly look at the bright planets. While Uranus and Neptune are evening planets, they require binoculars or a telescope to spot. All of the bright naked eye planets are in the morning sky now, However Saturn and Venus, the brightest are too close to the Sun to be seen. At 7 this morning Mars is in the south-southeast while Jupiter is a lot brighter and below and left of it. Mars will rise tomorrow morning at 3:49. It’s approaching Jupiter which will rise 23 minutes later at 4:12. Mercury will be a challenge to spot, rising in the east-southeast at 6:32 a.m. both today and tomorrow. At 7 a.m. It will require a low horizon, binoculars and luck to find. In its next evening appearance in March it will be placed much higher in the sky for the same twilight conditions.

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