The 66 million people had 240 million “interactions,” which includes posts, reactions, shares and comments. That was roughly the same number of “interactions” seen during the Super Bowl.

The most popular hashtags included, “#eclipse2017,” “#solareclipse2017” and “#totality.”

A visualization of the Facebook interactions as they were happening, embedded below, tracks with the path of the full eclipse, which ran from Lincoln Beach, Ore. to Charleston, S.C.

The nature of the eclipse also lent itself to live video: There were more than 129,000 Facebook live streams about the eclipse on Monday.

NASA’s Facebook Live had more eyeballs than any other live video of the day, with 29 million views. In case you missed it, you can still watch the video below.
