A coronal mass ejection — when plasma and magnetic particles burst forth from the sun’s surface — occurred on Sunday, the same day as the official start of fall, Space.com reported.

When most folks think of Autumn, browning leaves, crisp wind and pumpkins come to mind – for scientists, though, it’s solar storms. And one is likely to blitz the Earth today, according to meteorologists.
