doug — off the record

just a place to share some thoughts


We have what I’ve been reading as a rather unique event happening this week. We’re going to be witness to a partial lunar eclipse.

This eclipse is part of an “almost tetrad”—a series of four big lunar eclipses in two years. Three of these eclipses are total, while the November 18-19, 2021, is a deep partial eclipse. So deep that it is almost a total eclipse.

That’s the exciting part. The not-so-exciting part is that it will appear very early in the morning or very late in the night depending upon your sleeping habits. For me, it would be early in the morning.

Windsor is listed in this site as to when a person could observe this event. I’m looking at the time lines and some of the event are possible. Of course, the sky conditions would have to be accommodating to see things.

If not, there’s always the internet. And, speed it up to get the whole effect in a minimal amount of time.

If nothing else, it brings back terms that I haven’t seen used in years – penumbra and umbra. I also recall how my science teacher demonstrated eclipses with a flashlight and balls. It seems so primitive these days with all the technology that we have just a click away.

So, I might see part of this show live. I have great memories of a science teacher who used to go over the wall when opportunities like this happened to bring “real science” into the classroom. That memory makes part of this event worthwhile in itself. To actually see it would put it over the top.

My biggest challenge will be not waking the dog.

How about you?
