Amazing Sun Complex Magnetic Arches and Loops

Two active regions with their intense magnetic fields produced towering arches and spiraling coils of solar loops above them from June 29 through July 1, 2014, as these sunspot regions rotated into view.

When viewed in extreme ultraviolet light (EUV), the magnetic field lines are revealed by charged particles that travel along them. We cannot see extreme ultraviolet with our eyes, so we convert the EUV into artificially-colored yellow. In this video, these active sunspot regions appear as dark sunspots when viewed in filtered light.

Note the small blast in the upper of the two major active regions, followed by more coils of loops as the region reorganizes itself.
