  • Issued: Sat, 11 May 2024 06:33:41 +0000
  • Space Weather Message Code: ALTK06
    Serial Number: 561
    Issue Time: 2024 May 11 0633 UTC
    
    ALERT: Geomagnetic K-index of 6
     Threshold Reached: 2024 May 11 0626 UTC
    Synoptic Period: 0600-0900 UTC
     
    Active Warning: Yes
    NOAA Scale: G2 - Moderate
    
    NOAA Space Weather Scale descriptions can be found at
    www.swpc.noaa.gov/noaa-scales-explanation
    
    Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
    Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
    Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
    Radio - HF (high frequency) radio propagation can fade at higher latitudes.
    Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.
