Active Region on Sun Emits Another Flare

Video of a solar flare on Oct. 22, 2012, as captured by NASA’s Solar
Dynamics Observatory (SDO) in the 131 and 304 Angstrom wavelengths. The
131 wavelength of light is used for observing solar material heated to
10 million degrees Kelvin, as in a solar flare. The wavelength is
typically colorized in teal, as it is here.
