On a scale of 1-5, a Strong Geomagnetic Storm ranked as a 3
Some power systems could experience voltage alarms and transformer damage; voltage corrections may be required. False alarms could be triggered on some protection devices. Because surface charing may occur on satellite components, drag may increase on low-Earth orbit satellites, forcing ground operators to issue flight corrections to fix orientation problems. Satellite GPS navigation can be effected along with low-frequency radio communications.
A geomagnetic storm as potent as this one could also produce aurora, or “Northern Lights”, as far south as Illinois and Oregon.
