Nov 3

As predicted active area 1339 unleashed a M-class solar flare on November 2, with a peak in X-ray emission. 

The movie shows the flare in the 131 Angstrom wavelength and shows the plasma in the corona with temperatures up to about 15 Million Kelvin! (these high temperatures are observed in solar flares) and occur when Iron is super heated, having almost all of its electrons stripped away.
