This movie shows the evolution of the Sun's entire surface as seen in extreme ultraviolet light (304 angstroms) for the time period Jan 1 - Sep 27, 2012. The movie was made by combining nearly simultaneous view of the Sun from three spacecraft: STEREO AHEAD and BEHIND (seeing the Sun's far side) and the Solar Dynamic Observer (seeing the near side). This EUV light comes primarily from the solar chromosphere. The bright patches are active regions. Many dark prominence eruptions can also be seen.
The data is plotted in Carrington coordinates which are "fixed" to the surface of the Sun. In this coordinate system, the active regions tend to stay at the same location. However, the Sun's rotation rate actually changes with latitude and this can be seen in the movie.
