"This is prominence finery at its best," says photographer Pete Lawrence of Selsey, UK. "Small bright points within the prominence that were seen on the capture screen have been recorded as blurs due to the rapid motion of material in just a few seconds!"

Prominences are clouds of hydrogen held above the surface of the sun by magnetic fields. While this particular cloud appears to be raining like a summer shower on Earth, the true situation is more complicated. Look carefully: Some of the plasma raindrops are falling "up." That's because the motions are controlled by not only gravity but also magnetism, a force of little importance in terrestrial rainstorms. The solar magnetic field is rooted below the sun's visible surface; roiling motions in the body of the sun itself cause magnetic fields high overhead t

Oops, sorry, too long for comment!
