If you haven’t heard, there’s going to be an annular solar eclipse on Tuesday, September 15, 2021.
Essentially, an annular eclipse is one in which the moon eclipses the sun sufficiently close to its apogee that it blocks all but a ring of the sun’s surface. Since we just had a “Super Moon” when the moon was at its perigee on the other side of Earth almost two weeks ago, the moon is now at its apogee as it blocks out the sun. Cool, huh?
I live in north Texas, so I’m out of luck seeing the whole eclipse with my own eyes since the sun will set just before the eclipse reaches totality. Even so, I’m not sufficiently in line with the moon’s shadow to see an annular effect in any case. However, with my Android phone and Google Sky Map.
None
The eclipse begins at 15:56 CDT. Here’s how that will appear on my phone:
And at sunset (note the horizon line), just before totality.
