For days, astronomers have been monitoring a magnificent filament of magnetism stretching across the face of the sun. This morning, April 28th, it erupted. NASA's Solar Dynamics Observatory recorded the blast:
A coronal mass ejection (CME) is also emerging from the blast site: SOHO image. At first glance, the CME appears to be moving well away from the sun-Earth line. However, coronagraph data are too preliminary to rule out a glancing blow to our planet in the days ahead.
