01/04/2021 – Ephemeris – A belated preview of January skies

January 4, 2021

This is Ephemeris for Monday, January 4th. The Sun will rise at 8:20. It’ll be up for 8 hours and 56 minutes, setting at 5:16. The Moon, 2 days before last quarter, will rise at 11:29 this evening.

Let’s look ahead at the rest of January. Daylight hours will increase from 8 hours 56 minutes a day today to 9 hours 47 minutes on the 31st. The Sun’s noontime altitude above the southern horizon will increase from 22 ½ degrees today to 28 degrees on the 31st. The time of local noon, when the Sun is due south will be 12:52 pm on the 15th. The Straits area will have the Sun lower by a degree, and slightly shorter daytime hours. This month we’ll get into the heart of winter, and it’s going to be cold. This is moderated or intensified by the weather, which is always a wild card. In the night skies the winter stars, and Orion will make a bright display. Only Mars of all the naked-eye planets will be visible after twilight in the evening.

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

Note: The addendum of information about the month ahead has been added to my January 1st post here.
