On November 27 and 28, a series of powerful solar flares swept across the Sun’s surface, creating this coronal hole. This phenomenon is a temporary region of relatively cool, less dense plasma in the solar corona where the Sun's magnetic field extends into interplanetary space as an open field. The open magnetic field of a coronal hole allows solar wind to escape into space at a much quicker rate, leading to increased chances of geomagnetic storms upon colliding with Earth’s magnetosphere.
