FARSIDE EXPLOSION:
This morning, March 20th, a coronal mass ejection (CME) billiowed over the sun's western limb. Movie of the expanding cloud recorded by the Solar and Heliospheric Observatory (SOHO):
Imagery from NASA's STEREO-A spacecraft suggests this was a backside event. Despite multiple views from SOHO and STEREO, however, the precise location of the blast site remains uncertain. It might be an active region which is passing through STEREO's narrow blind spot on the "anti-Earth" side of the sun. Stay tuned for updates.
