Solar Flares - TRACE 171Å image, showing emission from gas at 1 million degrees, of Active Region 9077 on 19 July 2000, at 23:30UT. The image (rotated over 90 degrees, so North is to the left) shows a filament in the process of lifting off from the surface of the Sun. The dark matter is relatively cool, around 20,000 degrees, while hot kernels and threads around it are at a million degrees or more. From footpoint to peak, this rapidly evolving structure measures 75,000 miles. [Looks like the Phoenix rising, really spectacular]
Sunspot Loops - This ultraviolet image shows bright, glowing arcs of gas flowing around the sunspots.
Massive Solar Flare - This solar flare was observed by TRACE at 03:30UT on 12 April 2000, in the 171Å passband, characteristic of 1-million degree gas. The image was taken shortly after the flare started. It shows the primary flare site just right from the center. Very fast beams of energetic particles traveled along the field lines toward the left, which upon impact on the lower, cooler atmosphere light up along a curved track.
