I made this video using data from NASA's SDO satellite. It gives you a close-up view into a couple layers of the Sun's atmosphere. The details are much better if you watch it at YouTube in 720p HD.
The Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory is a series of devices set up to take images of the Sun every few seconds and through a variety of filters. This video is a 18-1/2 hour series of data gathered by the 304Å and 171Å filters. The 304Å filter is designed to see areas of cooler dense filaments and prominences of plasma above the visible surface of the Sun, while the 171Å filter is especially good at showing loops and arcs, activity mostly in the upper transition region and corona. The video shows an active region on the eastern limb from 00:00 to 18:30 on 2012-02-12. There are just over 3700 images used to make the frames for the video, 1850 of each wavelength. What you're seeing here is actual time sped up by almost 1000 times.
