Ephemeris: 10/13/2023 – Tomorrow’s solar eclipse
This is Ephemeris for Friday, October 13th. Today the Sun will be up for 11 hours and 6 minutes, setting at 7:01, and it will rise tomorrow at 7:56. The Moon, 1 day before new, will rise at 7:45 tomorrow morning.
The safest way to view tomorrow’s solar eclipse is by projection, we call it pinhole projection, although the pinhole can be up to 1/4 inch in diameter and will cast a usable image of the Sun about 6 feet. My wife once used the mirror in her compact to reflect the Sun’s image onto the north side of a building across the street. It’s probably too late to buy them, but if you have any eclipse glasses leftover from the 2017 eclipse make sure they don’t have any pinholes in them. They can be used to view the eclipse. Make sure they are ISO approved. Still projection is your safest bet. For our area the eclipse will last from 11:42 am to 2:18 pm. I’ll be at the Betsie Valley District Library in Thompsonville for the eclipse. You’ll be in good shape for next April 8th total eclipse, whose path of totality will be much closer to us.
Jerry Dobek, Northwestern Michigan College instructor will be on campus with telescopes to view the eclipse on campus.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT –4 hours). They may be different for your location.
Addenda
In case of clouds, I will still be at the Betsie Valley District Library with an alternate program of my experience with five previous total solar eclipses, and a look at some future eclipses. Being a NASA Solar System Ambassador, I’ll have some NASA stickers and other things to hand out to the kids, big or small.

The next solar eclipse
The next eclipse visible from our area will occur on April 8, 2024, six months from now. It will be a total solar eclipse whose path of totality is within a day trip from our area, if it’s clear in Indiana or Ohio. I’ll have a lot more information as we approach April. On the Internet search for american eclipse 2024, or words to that effect. It’s always best to plan early.
