GEOMAGNETIC STORM WATCH (G3): A series of three CMEs is now heading for Earth. The first two, launched by M-class flares on August 7th, are relatively minor. The third, launched by yesterday's X-flare (described below), is more potent. Striking Earth in succession on Aug. 9th, 10th, and 11th, the three CMEs could spark geomagnetic storms as strong as category G3 with mid-latitude auroras in the USA and Europe.
