One small flare

One small flare
The sun's only visible active region sputtered and spurted and eventually unleashed a small (C-class) flare (Feb. 7, 2018). The flare appears as a brief, bright flash about mid-way through the half-day clip. These images were taken in a wavelength of extreme ultraviolet light.
