A large solar flare occurred on 10 September 2017 at the edge of the Sun, and this movie shows the spectacular eruption that came from the flare. The images show plasma at a temperature of about 10 million degrees, and the flare is the extremely bright feature just above the edge of the Sun. The loop-like structure being ejected is referred to as a magnetic flux rope. The thin, straight line behind it is a current sheet (viewed edge on). Both features are as expected from the standard model of solar eruptive events, and this is a particularly nice example.

Images are from the Atmospheric Imaging Assembly of NASA's Solar Dynamics Observatory. The sequence lasts 10 minutes (see time in bottom-right corner). I've rotated the images by 90 degrees counter-clockwise. The flickering of the bright flare is due to the camera taking alternating short and long exposures.
