Safely (and cheaply) observe the eclipse

August 17, 2017

A quick note for all eclipse observers, but especially those who haven’t been able to find eclipse glasses: here’s the #1 best eclipse activity for kids, and not bad for adults, either. Each person needs a stack of index cards and a push-pin or thumbtack. They can pick out their names or make little drawings by punching holes in one index card, then use that to project little crescent suns on the other index card. Safe, foolproof, can easily eat up an hour or more. Everyone should do this, and take pictures and post them. Pics attached here are from the 2014 partial eclipse (observing report here).

I wrote up an observing guide (link) for people on the Western University of Health Sciences campuses in Lebanon, Oregon, and Pomona, California, but really this stuff applies for everyone on the path of totality (Lebanon) or off (Pomona). Except for the timings, and you can get local eclipse timings here. My more complete page on safely observing the sun is on the sidebar (link).

Good luck, and clear skies!
