Solar eclipse, Supermoon, Spring Equinox: Friday Will See Three Rare Celestial Events
From the article:
As the eclipse plunges the UK and other places into darkness this Friday, two other rare if less spectacular celestial events will be taking place, too: a Supermoon and the Spring equinox.
The equinox will happen at the same time as a solar eclipse in 2053 and 2072, though it doesn’t always appear as close together as that.
The title isn’t exactly correct. The Spring equinox happens every year. Maybe the three coinciding is what’s rare, I’m assuming.
