Seesaw Filament 
A laterally oriented structure in the Sun's corona seemed to balance itself (watch the area to the upper left) above the Sun's surface for at least two days (May 26-28, 2015). The structure seemed to fade about halfway through the video, but then reappeared even clearer than before. The activity was imaged in a wavelength of extreme ultraviolet light.
