After Sunday night’s fabulous auroral display – and with solar max on the horizon (due mid-decade) – we’re all wondering, when will we next see auroras?And the answer might be … soon. A coronal mass ejection (CME) is on its way to Earth. It came from a filament eruption, which blasted a great burp of solar material to space yesterday. Specialists estimate the CME will reach Earth by tomorrow afternoon, likely bringing G1 (minor) or G2 (moderate) disturbances to Earth’s magnetic field. Get ready for more auroras!
