On this page I have links to a few short animations of the aurora that I have put togeather from stills.
Click on each of these thumbnails to load the animation.
(The file sizes are right around 1 meg for each, so it will take a few moments depending on the speed of your connection.)
While there is nothing quite like the experiencing an active bright display of the northern lights first hand, these animations will give you a real feeling for the gentle motions of the aurora. Please enjoy.
