Here it comes. A coronal mass ejection (CME) launched into space on Oct. 28th by exploding sunspot AR2887 is heading almost directly for Earth. SOHO coronagraphs recorded the CME racing away from the sun faster than 1260 km/s (2.8 million mph):

The movie is full of "snow"--speckles caused by solar protons striking the coronagraph's CCD camera. These particles were accelerated toward the spacecraft (and toward Earth) by shock waves in the leading edge of the CME. Traveling at relativistic speeds, the protons reached us in less than an hour. The CME itself will take more than two days to cross the sun-Earth divide.
