Space Weather News for Jan. 23, 2012
INCOMING CME: Big sunspot 1402 erupted on Jan. 23rd, producing a strong M9-class solar flare and a fast-moving coronal mass ejection (CME). Analysts at the Goddard Space Weather Lab say the CME should reach Earth on Jan. 24th at 14:18 UT (+/- 7 hr) and Mars a little more than a day later. Strong geomagnetic storms are possible when the cloud reaches Earth. Our magnetic field is still reverberating from a CME impact on Jan. 22nd, so another blow could spark impressive auroras at high latitudes. Sky watchers in northern Europe, Canada, Alaska, and northern-tier US states such as the Dakotas, Minnesota and Wisconsin should be alert for Northern Lights.
Some day one of these things is going to take out our electrical grid. Then what?
