Twice a year, for three weeks near the equinox, NASA's Solar Dynamics Observatory (SDO) moves into its eclipse season — a time when Earth blocks its view of the sun for a period of time each day. Any spacecraft observing the sun from an orbit around Earth has to contend with such eclipses, but SDO's orbit is designed to minimize them as much as possible. On September 13, during the Fall 2012 eclipse season, SDO experienced on such eclipse followed by an unusually large, dark prominence that lifted up off the surface. The prominence was visible in extreme ultraviolet light with a wavelength of 304 angstroms. This wavelength highlights plasma with temperatures of around 50,000 Kelvin. The Atmospheric Imaging Assembly on NASA's Solar Dynamics Observatory captured the event at 4k resolution and a high imaging cadence of one image every 12 seconds.
