Sent: 240510/1911Z 4173@WG3K.#SMD.MD.USA.NOAM LinBPQ6.0.24
Space Weather Message Code: ALTK08
Serial Number: 32
Issue Time: 2024 May 10 1904 UTC
ALERT: Geomagnetic K-index of 8, 9-
Threshold Reached: 2024 May 10 1901 UTC
Synoptic Period: 1800-2100 UTC
Active Warning: Yes
NOAA Scale: G4 - Severe
NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation
Potential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude.
Induced Currents - Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify.
Spacecraft - Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur.
Navigation - Satellite navigation (GPS) degraded or inoperable for hours.
Radio - HF (high frequency) radio propagation sporadic or blacked out.
Aurora - Aurora may be seen as low as Alabama and northern California.
