Solar Coronal Oscillations, 1080p HD

Time lapse of an active region on the Sun rolling off the disk onto the western limb imaged by SDO/AIA on Nov 27, 2012. In this video, you can see a nice example of a coronal oscillation of magnetic field lines.
There is a small flare followed by the coronal loops "ringing"/oscillating.

Extreme ultraviolet wavelength: 171Å, ~ 1 mega-kelvin
