SOMETHING IN THE OFFING: Just behind the sun's eastern limb, a hidden sunspot is crackling with solar flares. Yesterday, NASA's Solar Dynamics Observatory recorded this movie of hot plasma leaping over the edge of the solar disk:


In the past day alone, Earth-orbiting satellites have recorded almost a dozen B-class solar flares. Such relatively weak flares would never be mentioned during Solar Max, but any flare is remarkable during the current period of deepening Solar Minimum. In the next day or so, the underlying sunspot will be revealed by solar rotation, and we shall see if it has potential for stronger explosions. Free: Solar Flare Alerts.
