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.
Solar radio bursts are caused by plasma instabilities that ripple through the sun’s atmosphere in the aftermath of powerful flares. With AR1476 poised for more eruptions, this ‘radio activity’ is likely to continue for days.
