The more the sphere of human experience increases, the more facts accumulate in science that indicate the influence of the environment on the personality, on its development and behavior. A. Chizhevsky |

33-4.67 | Fact | G Geomagnetic Storms Voltage corrections may be required, false alarms triggered on some protection devices. Surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems. Intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.). | S Solar Radiation Storms No deviations from the norm in the radiation environment were recorded. | R Radio Blackouts 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. | 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 No deviations from the norm in the radiation environment are predicted. | 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. | |
