Updated CME Information :
STRONG SOLAR ACTIVITY: When the CME from today's X-flare arrives, a geomagnetic storm might already be in progress. An earlier CME is en route and nearing our planet. According to analysts at the Goddard Space Weather Lab, the cloud, which was produced by an M2-class eruption from sunspot AR1429 on March 4th, could deliver a glancing blow to Earth's magnetic field on March 6th at 04:30 UT (+/- 7 hr).
