TWO DOOMED COMETS: It's not unusual for one comet to fall into the sun. On Feb. 16th, two comets did it. The Solar and Heliospheric Observatory (SOHO) recorded thier death dive:

Traveling in tandem, the two comets disintegrated as they approached the sun. The smaller one vaporized first, and the larger penetrated a bit deeper before it disappeared. Watch the full resolution movie for a better view.

GEOMAGNETIC STORM WATCH: Minor G1-class geomagnetic storms are possible on Feb 20th when a a co-rotating interaction region (CIR) is expected to hit Earth's magnetic field. CIRs are transition zones between slow- and fast-moving solar wind streams. Solar wind plasma piles up in these regions, producing shock-like structures that can spark bright auroras.

CHANCE OF MINOR STORMS: A stream of solar wind flowing from a southern hole in the sun's atmosphere is approaching Earth. NOAA forecasters say there is a chance of minor G1-class geomagnetic storms when the stream arrives on Feb. 20th. A co-rotating interaction region (CIR) traveling just ahead of the stream improves the chances that a storm will actually occur.

SUNSPOT NOT SO SCARY, AFTER ALL? Old sunspot AR2936 is back. It is now rotating into view over the sun's northeastern limb. Unless there is more of it hidden behind the edge of the sun, AR2936 is not as scary as we expected. Who would have guessed that a sunspot like this could produce a huge explosion like that? Perhaps the sun's rotation will reveal some additional menace later today. Stay tuned.
