About this work
This close-up video clip shows a pair of active regions (the brighter areas) move and change as they rotate with the sun over just a 17-hour period (Oct. 4-5, 2017). They were observed in a wavelength of extreme ultraviolet light that reveals plasma heated to over a million degrees. 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 them were serious.
