Massive explosion on the farside of the sun

On July 23, 2017 a spectacular explosion emerged from the farside of the sun.Coronagraphs onboard the orbiting Solar and Heliospheric Observatory (SOHO) tracked the fast-moving cloud as it billowed into space, according to the Spaceweather website.

NASA's STEREO-A spacecraft, which has a partial view of the sun's farside, identified the source of the blast as active sunspot AR2665. STEREO-A observed an intense flash of extreme UV radiation from the sunspot's magnetic canopy.
