NASA's Solar Dynamics Observatory captured agnetic arcs of plasma that spiraled above two active regions held their shape fairly well over 18 hours on Jan. 11-12, 2017.

Magnetic arcs of plasma that spiraled above two active regions held their shape fairly well over 18 hours (Jan. 11-12, 2017). The charged plasma is being controlled the magnetic field lines of the active regions. The field lines become clearly visible when viewed in this wavelength of extreme ultraviolet light. Often the arches bend and twist more dynamically than the relatively stable ones seen here.
