Last night, if you lived near Lake Michigan, and were awake at 1:30 a.m., and you looked up at the sky, you might’ve seen a bright flash and, also, at some point, heard a distinct boom. 

Dashcam footage from a police car (seen above) captured the scene pretty clearly: A meteor, descending from the night sky, burning up in the Earth’s atmosphere at a very high rate of speed. 

According to the Associated Press, it’s unclear what happened to the rock—whether it crashed into the lake or simply disintegrated in the sky. 

But meteorologists tracked it for a time on radar, including one who told the AP that it also gave off a sonic boom, a fiery ball that turned out to be a fleeting wonder instead of the apocalypse.
