One Small Flare

Feb. 15, 2018
NASA's Solar Dynamics Observatory observed the sun's only visible active region as it sputtered and spurted and eventually unleashed a small (C-class) flare on Feb. 7, 2018.

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. Normally, we do not pay much attention to flares this small, but it was just about the only real solar activity over the past week as the sun is slowly approaching its quiet period of the 11-year solar cycle. These images were taken in a wavelength of extreme ultraviolet light.
