01/27/2021 – Ephemeris – Let’s have a lookout for the naked-eye planets for this week

January 27, 2021

This is Ephemeris for Wednesday, January 27th. Today the Sun will be up for 9 hours and 37 minutes, setting at 5:44, and it will rise tomorrow at 8:05. The Moon, 1 day before full, will set at 8:23 tomorrow morning.

Let’s have a lookout for the naked-eye planets for this week. Mercury will be low in the west-southwestern sky around 6:15 pm or about a half hour after sunset. It will set at 7:18 pm. Saturn and Jupiter are too close to the direction of the Sun to be seen. Saturn has passed into the morning sky, while Jupiter will pass behind the Sun tomorrow. Neither of these planets are visible. It will be a month or more before even Saturn will be visible in the morning twilight. Mars can be found quite high in the south at 7 pm. It will actually be due south at 6:43 tonight. Mars is increasing its speed eastward through the constellation of Aries the ram and will set at 1:52 am. Venus will be hard to spot in the morning twilight after it rises at 7:26 am tomorrow.

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

Addendum

Mercury in evening twilight

Mercury in evening twilight at 6:15 pm tonight January 27, 2021. Created using Stellarium.

Mars finder

Mars and neighboring constellations for 7 pm tonight, January 27, 2021. Created using Stellarium.

Binocular Moon

The Moon as it might be seen in binoculars or low power telescope tonight at 7 pm, January 27, 2021. Created using Stellarium.

Venus rising in the morning

Venus in morning twilight over a water horizon. Around here that would be Lake Huron shortly after 7:30 am tomorrow January 28, 2021. Created using Stellarium.

The graphic illustrating the planets as seen in a telescope is on hiatus until Jupiter and Saturn clear the Sun in the morning sky in a couple of months. Mars appears too small to show any detail in a small telescope.

Planets and the Moon on a single night

Planets and the Moon at sunset and sunrise of a single night starting with sunset on the right on January 27, 2021. The night ends on the left with sunrise on the 28th. I’m afraid that the labels for Jupiter and the Sun overlap, since the planets and Sun are very close. Click on the image to enlarge. Created using my LookingUp program.
