Yesterday, Nov. 9th around 1330 UT, a magnetic filament in the vicinity of sunspot complex 1342-1343 erupted, producing a M1-class solar flare and hurling a CME into space. The Solar and Heliospheric Observatory recorded the progress of the expanding plasma cloud:

Although the eruption was not squarely aimed at Earth, the CME is likely to deliver a glancing blow to our planet’s magnetic field on Nov. 11th or 12th. This could add to the impact of another CME already en route. The earlier cloud was propelled by a filament eruption (movie) on Nov. 7th and is also expected to deliver a glancing blow on Nov. 11th.

Analyses of these events are still preliminary, and the forecast may change. For now it is safe to say that high-latitude sky watchers should be alert for auroras on Nov. 11-12. (SpaceWeather)
