摘要: Data recorded by the Geostationary Operational Environmental Satellites, frequency deviations derived from a CW-HF Doppler sounding system, and geomagnetic field strength variations obtained ground-based magnetometers were analyzed to study ionospheric solar flare effects. A model of radiation was constructed synthetic flux intensities satellite X ray observations, corresponding deviation electron density at various altitudes calculated. The evolution EUV associated maximum values responsible for excess studied in detail. It found that during flare, not only magnitude radiation, but also rate its change dramatically affects deviation. However, results confirmed intensity determines strength.
