Hypotheses

Their origin has not been positively identified. They have been explained as: * Coronal mass ejection CMEs often generate shock waves similar to what happens when an aircraft flies at a speed higher than the speed of sound in Earth's atmosphere ( sonic boom). The solar wind's equivalent of a sonic boom can accelerate protons up to millions of miles per minute—as much as 40 percent of the speed of light. *
