BIG NEW SUNSPOT: Just yesterday, sunspot 1035 was nearly invisible. Today, it is as wide as seven planet Earths. The fast-growing active region burst into view on Dec. 14th with a magnetic polarity that clearly identifies it as a member of new Solar Cycle 24. If the expansion continues apace, it could soon become the largest sunspot of the year. Check Source: http://spaceweather.com for movies, photos and updates.
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. STEREO movies: solar flare, CME.
