The Sun
Taken from the Solar and Heliospheric Observatory website:
SOHO is undertaking some special observation campaigns that involve its imaging the sun at a high cadence (about every 12 minutes) in a wavelength of light (304 angstroms) that captures activity not far above the Sun's surface. The images were produced by emissions of singly ionized helium. The resulting 300 frames, when sequenced into a video clip at 15 frames per second, give us three days of almost uninterrupted video from late on March 18 to March 21, 2006.
The most obvious feature is the one bright active region seen rotating from left to right, but a closer examination shows lots of little motions and jets and streaming plasma seen most easily along the Sun's edge.
If you're interested there is a higher resolution video which unfortunately exceeds my allowable putfile file size. You can view this version, as well as many other vids and pics at :The Solar And Heliospheric Observatory
