ALMOST NO CHANCE OF FLARES TODAY: Big sunspot AR2916 is turning away from Earth as it sets off on a 2-week trip around the farside of the sun. With its exit, the chance of solar flares has plummeted. NOAA forecasters estimate a 10% chance of M-class flares today, dropping to no more than 1% tomorrow.
