This has to be my favorite photo I captured during the August 21 solar eclipse from Charleston, SC. It shows a phenomenon called Baily’s Beads, which is caused by the last bits of Sun peeking through low points and between mountains along the limb of the Moon in the final moments before 100% totality. They’re only visible for a few seconds between the “diamond ring” effect (which I did not capture) and the appearance of the Sun’s outer corona, and I’m very happy to have caught them on camera!
It’s August and one of the most highly-anticipated astronomical events of the 21st century is nearly upon us: the August 21 solar eclipse, which will be visible as a total eclipse literally across the entire United States…but that doesn’t mean everywhere in the United States. Totality will pass across the U.S. in a narrow band about 60 miles wide starting along the northern coast of Oregon at 10:18 a.m. local time (PDT) and ending along the coast of South Carolina at 2:48 p.m. EDT. But that’s just totality—the full eclipse event will actually begin much earlier than that and end later, and its visibility won’t be limited to only that path. And while it’ll be happening overhead in the daytime sky you’ll need the right equipment to view it safely, whether you’re in totality or not.
Wait, you say, what’s the difference between totality and…not totality? And how is it caused? And why is this a big deal at all? If you’re wondering those things (and perhaps others) then this post is just for you. Below are answers to some common—and certainly not dumb—questions about the solar eclipse, brought to you by yours truly (with a little help from NASA and other eclipse specialists.)
