Two pairs of active regions observed in extreme ultraviolet light show the dynamic magnetic interplay between them (Aug. 3-4, 2010). Energetic plasma is drawn to the magnetic field lines above active regions and forms the highly structured coronal loops. Connecting lines can also be seen reaching across between for the two widely separated active regions seen in profile to the left. We are offering the full disk, 10-second clip at its highest resolution (4096 x 4096, 323MB), as well as at smaller sizes to reduce file size, to let our viewers experience the best level of detail of solar activity that SDO can offer.
