Space Weather News for Feb. 15, 2011
MAJOR FLARE: Earth-orbiting satellites have detected the strongest solar flare in more than four years. At 0156 UT on Feb. 15th, giant sunspot 1158 unleashed an X2-class eruption. X-flares are the strongest type of x-ray flare, and this is the first such eruption of new Solar Cycle 24. The explosion that produced the flare also sent a solar tsunami rippling through the sun’s atmosphere and, more importantly, hurled a coronal mass ejection toward Earth. This raises the possibility of geomagnetic storms in the days ahead. Visit http://spaceweather.com for images and updates.

SWEET AURORAS: Last night, as predicted, a gust of solar wind hit Earth’s magnetic field, sparking bright Valentine’s auroras around the Arctic Circle. Øystein Lunde Ingvaldsen sends this picture of the sweet lights over Bø in Vesterålen, Norway:
“It was a short but beautiful blast of Northern Lights,” says Ingvaldsen. “Perhaps this is a preview of things to come later this week.” Indeed, CMEs en route to Earth from exploding sunspot 1158 are expected to arrive on Feb. 15th-17th, prompting bright displays at even lower latitudes. Sky watchers should be alert for auroras.
