Fast growing sunspot and Magnetic filament eruption

FAST-GROWING SUNSPOT: Suddenly, sunspot AR3169 is growing. During the past 24 hours it has added a dozen moon-sized dark cores to the previously empty region between itself and trailing sunspot AR3171: movie. The boiling emergence of so much magnetic flux could destabilize the sunspot's magnetic field and trigger strong flares.Solar flare alerts: SMS Text. 

MAGNETIC FILAMENT ERUPTION: A CME may be en route to Earth following the eruption of a magnetic filament. It lifted off from the sun's northern hemisphere during the early hours of Dec. 24th:

Debris from the blast ripped through the sun's atmoshere and hurled a fast-moving CME into space. NOAA forecasters say it could hit Earth's magnetic field on Dec. 27th and spark G1-class geomagnetic storms.
