Reversing Prominence

A prominence rose up above the sun, sent an arch of plasma to link up magnetically with an active region over a one-day period (Jan, 9-10, 2017). Then the flow of plasma seemed to largely change direction and head back where it came from. Finally, amidst the confused patterns of movement, it dissipated and fell away. Prominences are cooler clouds of charged particles tenuously tethered to the sun by magnetic forces. Images were taken in a wavelength of extreme ultraviolet light.
