Region 10930 produced a major X3.4/4B proton flare
Region 10930 produced a major X3.4/4B proton flare peaking at 02:40 UTC on December 13. 4B is the maximum brightness on the brightness scale and occurs very rarely. Strong type II and IV radio sweeps were recorded and an intense proton storm started at Earth soon after the flare. It is likely that a major very fast Earth directed CME was caused by the flare.

Make that an X9 flare!
From spaceweather.com: Earth-orbiting satellites detected a major X9-class solar flare this morning at 1035 UT (5:35 a.m. EST). The source: big, new sunspot 929, which is emerging over the Sun's eastern limb. GOES-13 captured this X-ray image of the blast:
Because of the sunspot's location near the limb, the flare was not Earth-directed. Future eruptions could be, however, because the Sun's spin is turning the spot toward Earth. Sunspot 929 will be visible for the next two weeks as it glides across the solar disk.
