16 Dec 2009 CME

[Scarab]

INCOMING CME: This morning at 0120 UT, an eruption of magnetic fields around sunspot 1035 produced a long-duration C4-class solar flare and hurled a coronal mass ejection (CME) in the general direction of Earth. High-latitude sky watchers should prepare for auroras when the CME arrives on or about Dec. 18th.

BIG NEW SUNSPOT: New sunspot 1035 is growing rapidly and it is now seven times wider than Earth. This makes it an easy target for backyard solar telescopes. Yesterday, Rogerio Marcon of Campinas, Brazil, photographed a maelstrom of hot plasma and magnetic filaments connecting the sunspot's dark cores.
"Solar activity is picking up," he says.
