(NEXSTAR) — A "powerful coronal mass ejection (CME) erupted from the Sun" on Friday sparked severe-level geomagnetic storms on Earth, giving many across the U.S. the chance to see the northern lights Sunday night. If the activity in our atmosphere holds up, some could again have the possibility of seeing the aurora on Monday night.

NOAA's Space Weather Prediction Center warned of the CME, brought on by an M8 solar flare, last week. Because it was traveling toward Earth, the SWPC warned of strong geomagnetic storms, with the potential to reach G4-strength (on a scale of 1 through 5) through Tuesday.
