Over a 17-hour period, a pair of active regions – with solar plasma heated to over a million degrees – rotated into our Solar Dynamic Observatory’s view Oct. 4-5. They were observed in a wavelength of extreme ultraviolet light.
The arches above the regions consist of charge particles spinning along and revealing magnetic field lines. Each one shows a few minor bursts of material, none of which were serious.
