    "Twin" eclipse in 1970
    From: Frank Reed
    Date: 2024 Mar 30, 06:23 -0700

    Total solar eclipses repeat with similar circumstances every 18 years plus 10 and a third days. That's called the Saros cycle. The extra third of a day is useful if you don't mind travelling thousands of miles, but if you want to see the Saros "twin" of any solar eclipse, it's more useful to look back (or ahead) by three Saros cycles which comes out to 54 years and a month. That's a reasonable fraction of a human lifetime. So we turn back the clock and find memories of the April 8, 2024 total eclipse on March 7, 1970. Did you see that one?

    Below I'm attaching a standard eclipse totality map (originally from Wikipedia, credit Fred Espenak) and a front page story from the New York Times. The path of totality back then was a few hundred miles east and just clipped the US East Coast. How was the weather that day?
