Unusual Filament of Magnetism on the Sun

Magnetic filaments on the sun are not uncommon. Usually they are linear, stretching in only one direction. This one, however, curls back on itself, circumscribing a region more than 280,000 km in diameter. The unusual architecture of the region may undermine its stability. Magnetic fields that criss-cross, like mismatching ends of an incomplete circle, can explode–a process called “magnetic reconnection.” Any eruptions this week would likely be Earth-directed.
