AURORA WARNING v. Spaceweather

[Peter Wloch]

AURORA WARNING: A coronal mass ejection (CME) that billowed away from the Sun on Feb. 14 (0250 UT) is apparently heading for Earth. The expanding cloud could trigger geomagnetic activity when it sweeps past our planet on Feb. 16 or 17; sky watchers in northern Europe, Canada and the northern tier of US states should remain alert for Northern Lights.

There is a slim chance that an earlier CME, recorded by SOHO on Feb. 12, will deliver a glancing blow to our planet's magnetosphere on Feb. 15, triggering Northern Lights before the weekend begins.

Zuordnung schwierig, ob der Anstieg mit dem 12.2. zusammenhängt:
