Heliophysicists (physicists who study the Sun) have coined the term hedgerow prominences, which I find charming, for what we see below. From NASA/JPL/CalTech:
At the edge of the sun, a large prominence and a small prominence began to shift, turn and fall apart in less than one day (May 8-9, 2017). Prominences are notoriously unstable. Competing magnetic forces pulled the plasma back and forth until they dissipated. The images were taken in a wavelength of extreme ultraviolet light. The 18-second video clip is comprised of almost 600 frames being shown at 30 frames per second.
The movies are at the link above. These starkly gorgeous images of that big light in the sky really can entrance me.
