Sun - severe
143-6.33 | 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 Passengers and crew in high-flying aircraft at high latitudes may be exposed to elevated radiation risk. Infrequent single-event upsets possible. Small effects on HF propagation through the polar regions and navigation at polar cap locations possibly affected. | 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 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 forecast Minor impacts on HF radio in the polar regions. | R Radio Blackouts forecast Limited blackout of HF radio communication on sunlit side, loss of radio contact for tens of minutes. Degradation of low-frequency navigation signals for tens of minutes. | |
