WHAT'S IN THE OFFING? A new sunspot is approaching. For the past two days it has been crackling with flares and hurling material over the sun's northeast limb. NASA's Solar Dynamics Observatory photographed these glowing magnetic loops marking the spot of an M1-class explosion during the early hours of May 20th. The sunspot is on the sun's farside now, but solar rotation is carrying it in our direction. It a day or so it will emerge into view over the sun's eastern limb.
