CALLING ALL HAMS: No hobby is more sensitive to solar activity and space weather than ham radio. So here is a call to ham radio operators: Is spaceweather.com meeting your needs? We welcome your suggestions to improve our website. Submit ham-friendly ideas here.
SOLAR ACTIVITY: The sun is showing signs of life. There are no fewer than five active regions on the sun's surface, shown here in an extreme ultraviolet photo taken this morning by the Solar and Heliospheric Observatory (SOHO):
Each circle contains a sunspot or proto-sunspot belonging to new Solar Cycle 24. After two years of record-low sunspot numbers and many month-long stretches of utter quiet, this is a notable outbreak. Whether it heralds a genuine trend or merely marks a temporary, statistical uptick in activity remains to be seen. Stay tuned!

INCOMING CME: This morning dec. 17th 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.
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:
