SOLAR ACTIVITY: After days of quiet, two new active regions are rotating over the sun's eastern limb, heralding a possible uptick in solar activity. One of them erupted during the late hours of Dec. 7th, shown here in a movie from NASA's Solar Dynamics Observatory:
The untwisting magnetic filament hurled a fragment of itself into space but Earth was not in the line of fire.
The potential of these regions for more eruptions will become clearer as they turn toward Earth in the days ahead. For now, NOAA forecasters estimate a 20% chance of M-class solar flares during the next 24 hours. Solar flare alerts: text, phone.
