CME AND RADIATION STORM: A solar radiation storm is in progress on May 22nd following an M5-class explosion on the sun's western limb. The source of the flare, which peaked at 1332 UT, was departing sunspot AR1745. SOHO coronagraphs observed a magnificent CME emerging from the blast site: Update (May 22 @ 5:30 PDT): Although the explosion was not squarely Earth-directed, the CME will likely be geoeffective. The expanding cloud appears set to deliver a glancing blow to Earth's magnetic field on May 24th around 1200 UT. According to NOAA forecast models, the impact will more than double the solar wind plasma density around Earth and boost the solar wind speed to ~600 km/s. High-latitude sky watchers should be alert for auroras. http://www.spaceweather.com/
