We counted at least a dozen minor eruptions from this close-up video of an active region over a 30-hour period (Nov. 3-5, 2015). The eruptions included several small flares (seen as brief white flashes) and numerous tongues of plasma lashing out as the competing magnetic forces grappled with each other. The images were taken in a wavelength of extreme ultraviolet light that shows activity not far above the Sun's surface. Credit: Solar Dynamics Observatory, NASA.
