INCOMING CME, CHANCE OF STORMS: Big sunspot AR1967 is crackling with solar flares and hurling CMEs into space. The biggest CME so far was propelled away from the sun on Jan. 30th by an M6-class explosion in the sunspots magnetic canopy. It is expected to reach Earth on Feb. 2nd. The blast was not squarely Earth-directed. Instead, it will deliver a glancing blow to our planets magnetic field. NOAA forecasters estimate a 45% chance of polar geomagnetic storms when the cloud arrives on Sunday. High-latitude sky watchers should be alert for auroras.
