X-FLARE: Sunspot 930 erupted again this morning, producing a strong X3-class solar flare. The blast triggered an ongoing radiation storm and probably hurled a coronal mass ejection (CME) toward Earth. Auroras are possible when the CME arrives on Dec. 14th or 15th.

Note: The radiation storm mentioned above is of moderate intensity and, unless it strengthens greatly, poses no threat to astronauts orbiting Earth onboard the International Space Station or the space shuttle. The astronauts are protected by the walls of their spacecraft as well as by Earth's magnetic field.
