UPDATE: Coronagraph images from the Solar and Heliospheric Observatory (SOHO) and NASA's twin STEREO spacecraft show a faint coronal mass ejection emerging from the blast site and heading off in a direction just south of the sun-Earth line.
The cloud could deliver a glancing blow to Earth's magnetic field sometime on Nov. 14th or 15th. High latitude sky watchers should be alert for auroras on those dates.
EARTH-DIRECTED ERUPTION: Active sunspot 1123 erupted during the early hours of Nov. 12th, producing a C4-class solar flare and apparently hurling a filament of material in the general direction of Earth.
