X-FLARE: Sunspot 930 has just unleashed another big solar flare, an X3-class explosion at 0240 UT on Dec. 13th (9:40 pm EST on Dec. 12th).

As a result of the blast, a radiation storm is underway. Based on the energy and number of solar protons streaming past Earth, NOAA ranks the storm as category S2: satellites may experience single-event upsets ("glitches") and passengers in high-flying aircraft at high latitudes may be exposed to elevated radiation risk.

The explosion probably hurled a coronal mass ejection toward Earth. (Confirmation from SOHO is still pending.) Sky watchers should be alert for auroras when it arrives on Dec. 14th or 15th.
