EVIL TWINS? A pair of large sunspots has rotated into view over the sun's eastern limb. The two dark cores, collectively known as AR1654, are each big enough to swallow Earth four times over. NASA's Solar Dynamics Observatory took this picture of the twins during the early hours of Jan. 10th: The two sunspots are connected by a canopy of strong magnetic fields, which are presently crackling with low-level C-flares. Much stronger eruptions are possible. NOAA forecasters estimate a 40% chance of M-class flares and a 5% chance of X-flares during the next 24 hours. http://www.spaceweather.com/
