With no active regions currently on the face of the sun, NASA's Solar Dynamics Observatory observed a bristling active region showing numerous arches of bright, magnetic field lines blossoming out and towering above it beginning to rotate into view.

With no active regions currently on the face of the sun, a bristling active region has begun to rotate into view (Mar. 27-28, 2018). In this extreme ultraviolet view, the active region has numerous arches of bright, magnetic field lines blossoming out and towering above it. Whether this region will produce solar storms remains to be seen, but at least there is some new activity to observe. The video was produced with Helioviewer software.
