Original Caption Released with Image:

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.


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.
