One rather small active region popped off no fewer than 15 minor flares over 18 hours (July 30-31, 2102). The activity of diminutive sunspot AR1538 is a sign of tension in the region's magnetic field. The active region show to the right also contributed another three flares during the same time period. The images were taken in a wavelength of extreme ultraviolet light.
