In the latest eruption of the summer, the sun has burst forth with an X1.1 flare, one of the largest types possible.

The flare came just after 7 p.m. Friday, according to the U.S. Space Weather Prediction Center.

The flare came from a sunspot called Active Region 1515, which has been very active indeed recently, firing off more than a dozen medium Class M flares since July 3.

Space watchers had kept their eyes peeled for an X flare.
