RADIO-ACTIVE SUNSPOT: Huge sunspot AR1476 is crackling with M-class solar flares and appears to be on the verge of producing something even stronger. The sunspot's 'beta-gamma-delta' magnetic field harbors energy for X-class flares, the most powerful kind. Radio operators are recording strong bursts of shortwave static from the sunspot as it turns toward Earth. Visit http://spaceweather.com for sample recordings and forecasts.
