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.
