SPECTACULAR EXPLOSION

Magnetic fields on the sun's northeastern limb erupted
around 17:45 UT on April 16th, producing one of
the most visually spectacular explosions in years.
NASA's Solar Dynamics Observatory (SDO) recorded
the blast at extreme ultraviolet wavelengths.

The explosion, which registered M1.7 on the Richter Scale
of solar flares, was not Earth-directed, but it did hurl a CME
into space. Analysts at the Goddard Space Weather Lab
have analyzed the trajectory of the cloud and found that it
will hit NASA's STEREO-B spacecraft, the Spitzer space
telescope, and the rover Curiosity en route to Mars.
Planets Venus and Mars could also receive a glancing blow.
