What Is A Coronal Hole?
The National Centers for Environmental Information defines coronal holes as, "dark regions in the sun’s atmosphere detected by ultraviolet and X-ray imaging, are the source of high-speed solar wind streams.
The winds generated by the coronal hole pass virtually unhampered into space. Sometimes present for many months, the holes rotate as the sun rotates every month. These high-speed streams collide with the slow solar wind that is generated outside the holes.
The visual effect resembles the spiral of a rotating sprinkler, which scientists call the Parker Spiral. This collision can lead to the formation of shockwaves in the solar wind and can produce disturbances to Earth’s magnetosphere, the protective magnetic field that surrounds the planet for thousands of miles above the surface."
