01/09/2020 – Ephemeris – What is Ephemeris about?

January 9, 2020 2 comments

Ephemeris for Thursday, January 9th. Today the Sun will be up for 9 hours and 1 minute, setting at 5:20, and it will rise tomorrow at 8:18. The Moon, 1 day before full, will set at 8:15 tomorrow morning.

The Ephemeris program has been a labor of love of mine for going on 45 orbits of the Sun this June. The topics are astronomy and space. What can be seen with the naked eye, binoculars or a small telescope. We look at constellations visible in the evening, their stories, both of western civilization and of the native peoples of our land. We look at the planets, especially the naked-eye planets on Wednesday, and whenever the Moon appears close to one to point it out. We also give heads up on upcoming events like eclipses and meteor showers, plus local events like viewing opportunities we call star parties. I have a companion blog, often illustrated: It’s at bobmoler dot wordpress dot com.

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


When the Moon is in the evening sky I will talk about what can be seen on its surface that night, usually near the terminator, which in the evening is the sunrise line, where the shadows are longest. I don’t cover the Moon every month.  Search “Moon” to find all the posts that I do.  I just might have a post on the phase you are interested in. Otherwise when the bright Moon overpowers the constellations, I talk about what we know about the bright stars visible, astronomical news or concepts, whatever can be explained in 45 seconds. Sometimes I can only whet your appetite.  Click the about button above for more information about the Ephemeris program and me.
