Warning-Geomagnetic Storm Category G5 Predicted Sunday 5-12-24

National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center has issued a Geomagnetic Storm Category G4 or Greater Prediction

In this Solar Maximum 11-year cycle, Geomagnetic Solar Storms effect on the planet and near-earth space could be severe and on Sunday 5-12-24. We have the potential for one of the most powerful solar system events known to man, which is a G5 Geomagnetic Storm, and could greatly affect our power grids and electronics.

Affected components could be spacecraft, power grids, navigation systems, and radio systems.

Space Weather Message Code: WATA99
Serial Number: 7
Issue Time: 2024 May 11 1753 UTC

  • Highest Storm Level Predicted by Day:
    • May 12: G5 (Extreme)
    • May 13: G3 (Strong)
    • May 14: G1 (Minor)

THIS NOAA SPWC WARNING SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT

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.

NOAA Space Weather Solar Geomagnetic Storm Scale

ScaleDescriptionEffect / Reaction
G5*ExtremePower systems: Some power grid systems may experience complete collapse or blackouts. Transformers may experience damage.
Spacecraft operations: May experience extensive surface charging, problems with orientation, uplink/downlink, and tracking satellites.
Other systems: HF (high frequency) radio transmission may be impossible in many areas for days or more.
G4SeverePower systems: Possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid.
Spacecraft operations: Possible surface charging, tracking, and orientation problems.
Other systems: HF radio propagation is sporadic, satellite navigation is degraded for hours, and low-frequency radio navigation is disrupted.
G3StrongPower systems: Voltage corrections may be required, and false alarms triggered on some protection devices.
Spacecraft operations: Surface charging and 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, and HF radio may be intermittent.
G2ModeratePower systems: High-latitude power systems may experience voltage alarms, and long-duration storms may cause transformer damage.
Spacecraft operations: Corrective actions required and possible changes in drag affect orbit predictions.
Other systems: HF radio propagation can fade at higher latitudes.
G1MinorPower systems: Weak power grid fluctuations can occur.
Spacecraft operations: Minor impact on satellite operations possible.
Other systems: Migratory animals are affected at G1 and higher levels.
