Solar Eclipse in San Francisco

May 21, 2012

It’s a paradox. Solar eclipses are much more rare than lunar eclipses, and so much more of an Event. Yet because the sun is so bright it could damage our eyes, we can’t really experience them directly, as we can eclipses of the moon. Instead, we have to seek the evidence in images and reflections.

Nevertheless, yesterday’s solar eclipse was exciting. The 84% maximum changed the quality of the light, and the leaf-shadows on the wall became attenuated crescents.  We watched the eclipse through pinhole images thrown on the wall.

Next time, I think I’m going to invest in the #14 Welders’ Glasses they recommend for eclipse-viewing. I want to actually look at a solar eclipse. Haven’t done that in years.

    I had a pair of solar glasses which I bought from Edmund Scientifics for $1.95.

    I viewed the eclipse from the Marina with hundreds of other people.
    The SF Amateur Astronomers had several telescopes set up and we were able to see it through the telescopes. One telescope had it set up so we could see it on a screen.
    I’ll send a photo via email.

      Thanks, Mary! I’m getting some of those glasses, and I’d be happy to post your photo.
