The Solar and Heliospheric Observatory (SOHO) and NASA’s STEREO-B spacecraft detected a CME rapidly emerging from the blast site: movie<\/a>. Analysts at the Goddard Space Weather Lab say the leading edge of the CME will reach Earth on Jan. 24 at 14:18UT (+\/- 7 hours). Their animated forecast track shows that Mars is in the line of fire, too; the CME will hit the Red Planet during the late hours of Jan. 25.<\/em>
\n This is a relatively substantial and fast-moving (2200 km\/s) CME. Spacecraft in geosynchronous, polar and other orbits passing through Earth’s ring current and auroral regions could be affected by the cloud’s arrival. In addition, strong geomagnetic storms are possible, so high-latitude sky watchers should be alert for auroras.<\/em><\/p>\n
