Sun - severe
127-7.33 | 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 Radiation hazard avoidance recommended for astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk. Single-event upsets, noise in imaging systems, and slight reduction of efficiency in solar panel are likely. Degraded HF radio propagation through the polar regions and navigation position errors likely. | R Radio Blackouts No deviations from the norm in the radio interference environment were recorded. | 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 Wide area blackout of HF radio communication, loss of radio contact for about an hour on sunlit side of Earth. Low-frequency navigation signals degraded for about an hour. | |
