Eclipse party!

Unless you’ve been living in a seriously deep hole under  a big rock, you know that there’s going to be a solar eclipse coming up this August. It’s the first one that will be crossing the entire US in quite a while. All of North America will be able to see at least a partial eclipse, and a good chunk of the US will get to see 90% or more of the sun in eclipse.

The US path of the August 21 total solar eclipse starts in Oregon at around 1600UTC (10:00 AM PDT) and ends in South Carolina a little after 2000UTC (4:00 PM EDT).

Back at the old house, we were just at the right edge of the path of totality. Our new house is much closer to the middle of the path (about 22 km from the center as the crow flies) and will be a much better place to watch the eclipse from. In addition, aside from houses, we have an almost unobstructed view of the entire sky from the house and a great big field to hang out in at the end of the street (if the yard gets too crowded).

See that path of totality? We’re practically right in the middle of it.

The last solar eclipse I was able to watch was back when I was in elementary school. I remember all the windows of the school had been covered up with paper, and nobody was allowed to go outside during the eclipse. Welding shades were taped to the windows of several doors so that kids could look up at the sun to see the eclipse.

The plan for this eclipse is to acquire a few #14 welding shades and make at least a couple of pinhole cameras for friends and neighbours to view the eclipse with.

Hopefully the weather will be good. August is starting to get into the peak of the hurricane season. Don’t want one of those coming by at the wrong time and messing things up.
