The NOAA Space Weather Prediction Center has observed extreme (G5) geomagnetic conditions Friday afternoon and expect severe (G4) conditions to continue through the weekend.
-
A Geomagnetic Storm of this strength can cause multiple and widespread issues with various power and communication systems.
-
Widespread voltage control problems may occur; some power grid systems may experience component failures, disruption of service and protective device trips. This could result in blackouts.
-
Pipeline currents can reach hundreds of amps.
-
GPS and other satellite navigation may be degraded or unavailable for days.
-
High Frequency (HF) radio propagation may be impossible in many areas for one or two days.
-
Low-frequency radio navigation can be out for hours.
-
Aurora may be visible at much lower latitudes.
