EARTH-DIRECTED CME
EARTH-DIRECTED CME:
A dead sunspot exploded today. The corpse of AR2987, which decayed days
ago, erupted, and the debris is heading straight for Earth. A CME
expected to arrive on April 14th could spark moderately-strong G2-class
geomagnetic storms. Full story @ Spaceweather.com.
