This is a movie produced from 30 images of the Sun taken by the Soft X-ray Telescope (SXT) on-board the Yohkoh orbiting solar observatory. The images were taken one day apart during the month of January 1994 and show one complete rotation of the Sun. The bright spots are regions composed of very hot magnetically contained X-ray emitting plasma. Over time, one can see the visible loops brighten and fade, as well as see new loops brought into view by the Sun's rotation as old ones move behind the Sun's limb. For more information on Yohkoh and solar X-rays see the Yohkoh SXT Homepage.
I also have an animation of the Sun at optical wavelengths.
This animation was produced by Lee Carkner using images available from the Yohkoh image gallery.
