01/07/2015 – Ephemeris – Lets take our first looks at the bright planets and a pretty bright comet

January 7, 2015

Ephemeris for Wednesday, January 7th.  The sun will rise at 8:19.  It’ll be up for 8 hours and 59 minutes, setting at 5:18.   The moon, 3 days past full, will rise at 8:10 this evening.

Lets take our first look at the bright planets for 2015.  Mercury is visible below right of Venus by about 2 moon widths low in the southwest shortly after sunset.  On Saturday Mercury will be its closest to Venus.  Mercury will set at 6:38, while Venus will set at 6:44 p.m.  They will be visible low in the southwestern twilight by 6 p.m.  Mars is low in the southwest at 7 p.m. and is in the constellation of Capricornus and will cross the boundary into Aquarius tomorrow. The Red Planet will set tonight at 8:37 p.m.  Jupiter will rise in the east at 8:02 p.m.  It’s near the sickle-shaped head of Leo the lion.  Early risers will be able to spot Saturn which will rise in the east-southeast at 4:46 a.m.  On the 18th it will cross the border from Libra to Scorpius.

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

Quasi-conjunction of Venus and Mercury

Animation of the Quasi-conjunction of Venus and Mercury. Time span 1/05/2015 to 1/15/2015 at 7 p.m. Created by Bob Moler using Stellarium and GIMP.

Note that Mercury gets dimmer as the days go by.  This is because its phase moves from gibbous to half illuminated on the 14th at its greatest elongation from the Sun.

Comet C/2014 Q2 (Lovejoy)

Comet Lovejoy track

Comet Lovejoy track for January 7 to January 13, 2015. Despite the magnitudes being less than 6, binoculars will, most likely, be needed to spot it. Every other day is marked with month-day and magnitude of the comet.

    It’s brighter than 5 tonight, 4ish. I could spot it with 50mm binoculars in Detroit as a green round nebulosity, fairly bright green. With a 75mm lens at f/4 6 second exposure ISO 1600, I was able to capture an image. It’s looking good… Brighter the next couple of days.

      Hi Scott,

      Nice to hear Lovejoy’s brightening up. Dang clouds around here. On December 28th when the comet was passing M79 Jerry Dobek was disappointed with its brightness. It was dimmer than M79 that it was passing that night. This should be the period of greatest brightness about now.

      Bob
