A series of elliptical loops

A series of elliptical loops seemed to droop down out of an active region on the Sun that was rotating into view (Dec. 7-9, 2014). The loops are actually particles spiraling along magnetic field lines when viewed in a wavelength of extreme ultraviolet light. Above this group other loops above another active region are tighter and less elongated, but always changing as well. The video covers two days of activity.
