12/05/2018 – Ephemeris – The bright planets and a comet tonight

December 5, 2018

Wednesday, December 5th. The Sun will rise at 8:04. It’ll be up for 8 hours and 58 minutes, setting at 5:02. The Moon, 2 days before new, will rise at 7:08 tomorrow morning.

Let’s look at the bright planets for tonight. In the evening sky we have Mars, but are about to lose Saturn. Saturn will be briefly visible very low in the southwestern sky from about 5:45 p.m. until it sets at 6:46 p.m. Mars will be in the south as the skies darken tonight. Mars will be due south at 6:41 p.m., and it will set at 12:13 a.m. Mars is moving eastward, crossing the constellation of Aquarius until the 21st, then it enters Pisces. Comet Wirtanen is moving northward, below and right of the V of stars that’s the head of Taurus the bull, and should be an excellent binocular object. Venus, our brilliant morning star, will rise at 4:24 a.m. in the east-southeast. The blue-white star Spica is still off to the right and a bit above it.  Mercury will rise at 6:31 a.m. and might be spotted after that.  Jupiter is near the Moon tomorrow morning, rising at 7:24 only 40 minutes before the Sun.

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

Planets and the Moon on a single night

Planets, one comet and the Moon at sunset and sunrise of a single night starting with sunset on the right on December 5, 2018. The night ends on the left with sunrise on the 6th. Click on the image to enlarge. Comet Wirtanen is very close to opposition and to the south, so it rises after sunset and sets before sunrise. Created using my LookingUp program.

Bright comets

Comet C/2018 V1

Comet C/2018 V1 (Machholz-Fijikawa-Iwamoto) in twilight starting tonight November 28, 2018. The comet won’t climb that dramatically at 6 p.m. on the rest of the nights because the stars in the field will set 4 minutes earlier each successive evening. The latest magnitude estimate of the comet on December 8 is 5.9, two magnitudes brighter than shown here. Created using Cartes du Ciel (Sky Charts).

Comet Wirtanen

Comet 46P/Wirtanen positions for the next week. Positions are marked with month-date and magnitude. The latest magnitude prediction for December 1st is 3.7, 5.4 magnitudes brighter than shown here. The comet may make magnitude 3 by mid-December. Star field position is for 9 p.m. on the 28th. Click on the image to enlarge. Created using Cartes du Ciel (Sky Charts).
