G3 (Strong) Geomagnetic Storm Conditions Observed
- lgats 5y agoContext: G 3 [Strong ] Kp = 7 Frequency: 200 events per cycle / 130 days per cycle Power systems: Voltage corrections may be required, false alarms triggered on some protection devices. Spacecraft operations: Surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems. Other systems: Intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.). https://www.swpc.noaa.gov/noaa-scales-explanation https://www.swpc.noaa.gov/noaa-scales-explanation
