Geomagnetic storm FAQ
What is a geomagnetic storm?
A disturbance of Earth's magnetic field driven by the solar wind, usually after a coronal mass ejection or a fast stream from a coronal hole. NOAA rates storms G1 to G5 by Kp: Kp 5 is G1, Kp 9 is G5. For aurora watchers, a storm means the oval moves toward the equator.
How far south will the aurora be visible in this storm?
Compare the storm's Kp with your city's threshold: every city page shows it. As a rule of thumb, G1 reaches the northern US border and Scotland, G2 the Great Lakes and England, G3 the central US and Melbourne, and G4–G5 much further.
Are geomagnetic storms dangerous?
Not to people on the ground. Strong storms can disturb power grids, satellites, GPS accuracy and high-frequency radio, which is why NOAA issues watches and warnings. For skywatchers they are the nights worth staying up for.
