This morning around 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The blast produced an M2-class solar flare, an S1-class radiation storm, and a massive CME.

Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) are still monitoring the CME as it billows away from the sun. Watch the cloud expand. The speckles are caused by energetic charged particles hitting the camera's CCD array. This is what we mean by a "radiation storm"; the particles were accelerated by the explosion and are now peppering Earth-orbiting satellites and spacecraft like SOHO.

Although the blast was not squarely Earth-directed, it will affect our planet. The CME should deliver a glancing blow to Earth's magnetic field during the late hours of June 8th or June 9th. High-latitude sky watchers should be alert for auroras when the CME arrives.
