Sun - severe
143-4.00 | Fact | G Geomagnetic Storms Possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid. May experience surface charging and tracking problems, corrections may be needed for orientation problems. Induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.). | S Solar Radiation Storms Minor impacts on HF radio in the polar regions. | R Radio Blackouts Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact. Low-frequency navigation signals degraded for brief intervals. | Forecast | G Geomagnetic Storms forecast High-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage. Corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions. HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.). | S Solar Radiation Storms forecast Minor impacts on HF radio in the polar regions. | R Radio Blackouts forecast Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact.
