SDO watched for many days as this snaking, elongated filament rotated around with the Sun. If straightened out, it would reach almost across the diameter of the Sun, about 1 million miles or 100 times the size of Earth. This one is longer than any we have observed in quite awhile. The image and movie was produced by blending images taken in two wavelengths of extreme UV light (Sept. 30, 2014). Filaments are clouds of gas suspended above the Sun by powerful magnetic forces.
