Possible impacts of space weather

Geomagnetic Activity
Activity Levels	Possible Impacts
Quiet	Power Systems: Impacts are not expected Aeromagnetic surveys: Impacts are not expected Directional Drilling: Impacts are not expected
Unsettled	Power Systems: Impacts are not expected Aeromagnetic surveys: Impacts are not expected Directional Drilling: Impacts are not expected
Active	Power Systems: Impacts are not expected Aeromagnetic surveys: Potential for disruption Directional Drilling: Potential for deviations
Stormy	Power Systems: Possibility of weak voltage fluctuations Aeromagnetic surveys: Potential for significant disruptions Directional Drilling: Potential for significant deviations
Major Storm	Power Systems: Geomagnetically induced currents may cause misoperation of protective relays and transformer heating Aeromagnetic surveys: Potential for severe disruptions Directional Drilling: Potential for severe deviations
