The possible geomagnetic storm caused by a ‘coronal hole’ on the sun: How will it affect Earth?
The geomagnetic storm caused by a ‘coronal hole’ on the sun possible: How it will impact Earth and what to do about it: Here’s a summary of what you need to know about the solar coronal hole. What is a coronal hole? A coronal hole is a region of the sun where the electric fields are weaker than usual. The sun’s magnetic field is generated by the convection of hot plasma from the sun’s core to the surface. The magnetic field lines are twisted and stretched as they rise to the surface. The sun’s magnetic field lines are like a giant rubber band. When the sun’s magnetic field lines are stretched, they snap back to their original shape.
