TRACE observed a this filament/prominence coming over the solar limb on 27 November 1999, in its 171Å passband (1 million degrees), as shown in this (QuickTime; JPEG/A compressed; 2.1MB) 1-day movie. The cool material in the filament sloshes back and forth, absorbing the emission from the hot gas behind it. We don't know what causes these motions, or even whether they are true tornadoes, or rather just sliding back and forth as the magnetic field that supports the cool material changes its configuration.
