Extreme geomagnetic conditions observed, severe geomagnetic storms expected to continue
The NOAA (Nation Oceanic and Atmospheric Administration) 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.
