Stronger blasts of energy, particularly during Extreme G5 storms, can be much more devastating for human infrastructure.
The SWPC said: “Power systems: Widespread voltage control problems and protective system problems can occur, some grid systems may experience complete collapse or blackouts. Transformers may experience damage.
“Spacecraft operations: May experience extensive surface charging, problems with orientation, uplink/downlink and tracking satellites.
“Other systems: Pipeline currents can reach hundreds of amps, high-frequency radio propagation may be impossible in many areas for one to two days, satellite navigation may be degraded for days, low-frequency radio navigation can be out for hours, and aurora has been seen as low as Florida and southern Texas.”
