RESTLESS SUNSPOT: The magnetic canopy of sunspot AR1654 is in a state of unrest, relentlessly shifting, reconnecting, and crackling with minor flares. The sunspot's magnetic field, illuminated above by the extreme UV glow of hot plasma and flares, has a 'beta-gamma-delta' configuration. That means it harbors energy for powerful X-class eruptions. So far, however, the sunspot has failed to produce a major eruption. Perhaps the tension is being relieved prematurely by restless fidgeting. NOAA forecasters estimate a 5% chance of X-flares during the next 24 hours. www.spaceweather.com
