Just a quick note to say some people may be able to see an aurora tonight that wouldn’t normally see one. A Kp 7 Geomagnetic storm is in progress (BOM estimate). In the Northern Hemisphere only Kp5 reported. Aurora Australis (Southern Lights) sighted in not just Tasmania but also southern WA. Unusual.

A CME JUST HIT EARTH: However, it might not be the “Big One.” A CME hit Earth’s magnetic field on Dec. 1st at 0021 UT, jolting the USGS magnetometer in Frericksberg, Virginia, by 36 nT. This could be the first of two CMEs en route to Earth. NOAA forecasters expect a significant Cannibal CME (composed of multiple storm clouds) to reach Earth midday on Dec. 1st, possibly sparking strong G3-class geomagnetic storms. Aurora alerts: SMS Text
Nullschool has predictions for visibility (but has seemed to underestimate the odds lately — people have reported and taken photos from spots that in theory should not be able to see anything.) Hard to predict.
