A small prominence hovered above the sun's surface over a two-day period (June 12-14, 2018) before breaking off into space. Prominences are cooler, darker clouds of plasma tethered above the sun by magnetic forces. These clouds of gases are notoriously unstable. The images were taken in the 304 Angstrom wavelength of extreme ultraviolet light.
