"Info: First X-flare of the New Solar Cycle"

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
