ARLA/CLUSTER: Explosão massiva no Sol de Classe C5

[João Costa > CT1FBF]

Massive explosion on the sun

Old sunspot AR2644 has returned following a 2-week trip around the
backside of the sun--and it is still active.

During the late hours of April 18th, the sunspot's magnetic canopy
exploded, producing a C5-class solar flare and hurling a spectacularly
bright coronal mass ejection (CME) into space.

The massive cloud of hot plasma will almost certainly miss Earth, but
future explosions could be geoeffective as the sunspot turns toward
our planet.
