Centeropoints are holes in the Sun’s upper atmosphere, where the plasma is less dense and cooler than in other parts of the solar system.
On a scale similar to storms occurring within Earth’s atmosphere, storms are measured, with each end depicting its risk to Earth, from mild to significant.
Two “large” solar flares have been watched in the sun with aurora borealis possible.
The G5 is the most dangerous while minor G1 hurricanes are expected to cause little variability in the electrical systems and “minor impact on satellite operations.”
While the sun’s magnetic field is largely closed, coronal holes have an open field extending into interplanetary space whereby solar winds can run of.
