At the edge of the sun, a large prominence and a small prominence began to shift, turn and fall apart in less than one day on May 8-9, 2017. Prominences are notoriously unstable. Competing magnetic forces pulled the plasma back and forth until they dissipated. The images were taken in a wavelength of extreme ultraviolet light. The 18-second video clip is comprised of almost 600 frames being shown at 30 frames per second.
