@nasa : The sun unleashed no less than five solar flares in five days this week all from the same dynamic active region (June 21-25, 2015). Many of these were associated with coronal mass ejections, most of which impacted Earth and generated beautiful auroral displays. The images were taken in a wavelength of extreme ultraviolet light. Flares are the bright flashes you see, followed by spirals of magnetic field lines as the active region reorganizes itself.
