BOULDER, Colo., Dec. 30 (UPI) -- Earlier this week, NOAA's Space Weather Prediction Center reported an M1 solar flare and associated coronal mass ejection. The resulting geomagnetic storm hit Earth Wednesday morning.
The center's forecast, published Tuesday, predicted a stronger G3 storm to last through Wednesday and a lesser G1 storm to persist through Thursday. The storming may result in the appearance of an aurora.
