Solar astronomy
At the World Space Congress a few weeks back, I noticed on one of the displays, a SOHO movie of the previous week up to the present of the following three movies and on the 15th there was a filament that was nicely visible in the 195 band (EIT Green). Usually these aren't seen as nicely in this shorter wavelength.
Anyhoo, you can watch it erupt into a coronal mass ejection (CME) and watch the magnetic cascade propagate on the visible surface of the sun. Then check out the other two movies to see the Coronal Mass Ejection leave the corona.
