SDO sees a whole series of loops towered above a group of active regions over a five-days period on July 9-13, 2015.
A whole series of loops towered above a group of active regions over a five-days period on July 9-13, 2015. When viewed in extreme ultraviolet light, magnetic field lines above the sun’s surface are revealed by light emissions from charged particles that spin along the lines and create these loops. They are best observed along the edge of the sun, as they are here. The tallest of the loops reach up about 15 times the diameter of Earth. Credit:NASA/SDO/Steele Hill
