BIG SUNSPOTS: Sunspots 1164 and 1166 are so large, people are noticing them at sunrise and sunset when the sun is dimmed by clouds and haze. The dark cores of these regions are many times wider than Earth, so they are conspicuous even from a distance of 93 million miles. Readers who monitor the spots using properly-filtered backyard telescopes are likely to see flares in action; sunspot 1164 in particular has a delta-class magnetic field that harbors energy for X-class eruptions

AURORA WATCH: A coronal mass ejection (CME) is en route to Earth, due to arrive on March 6th. The CME is slow-moving and not especially massive. Nevertheless, its arrival could provoke geomagnetic storms around the Arctic Circle. High-latitude sky watchers should be alert for auroras.
Even without a CME, the skies over Abisko National Park in Sweden are already active. Chad Blakley took this picture before daybreak on March 5th:

The STEREO (Ahead) spacecraft caught a large coronal mass ejection as it roared away from the Sun and out into space in the opposite direction from Earth (Feb. 26-28, 2011). The bright cloud of particles was one of most substantial eruptions that STEREO has observed. The major blast was followed by a much narrower and less bright one. The video clip covers a little more than two days. In these corongraph images, the Sun is blocked out by the red occulting disk and the size of the Sun is represented by the white circle.

IMPACT! A CME hit Earth's magnetic field at approximately 0100 UT on Feb. 18th (8:00 pm EST on Feb. 17th). The impact was not as strong as expected considering the cloud's X-class origin. Nevertheless, geomagnetic storms are possible in the hours ahead. High-latitude sky watchers should be alert for auroras.
