A relatively small active region erupted twice in 18 hours (Mar. 2, 2018). After each burst, one can see the magnetic fields lines, which appear as bright coils, spiraling around the region. They are reorganizing the disrupted magnetic field. The quick second when the screen goes black was caused by the Earth passing between the spacecraft and the sun. Images were taken in a wavelength of extreme ultraviolet light. The video was produced using the free Helioviewer software at Helioviewer.org.
SDO is managed by NASA's Goddard Space Flight Center, Greenbelt, Maryland, for NASA's Science Mission Directorate, Washington. Its Atmosphere Imaging Assembly was built by the Lockheed Martin Solar Astrophysics Laboratory (LMSAL), Palo Alto, California.
