摘要

An analysis of D-region electron density height profile variations, inducedby four isolated solar X-ray flares during period from September 2005 toDecember 2006, based on the amplitude and the phase delay perturbation of 22.1kHz signal trace from Skelton (54.72 N, 2.88 W) to Belgrade (44.85 N, 20.38 E),coded GQD, was carried out. Solar flare data were taken from NOAA GOES12satellite one-minute listings. For VLF data acquisition and recordings at theInstitute of Physics, Belgrade, Serbia, the AbsPAL system was used. Startingfrom LWPCv21 code (Ferguson, 1998), the variations of the Earth-ionospherewaveguide characteristic parameters, sharpness and reflection height, wereestimated during the flare conditions. It was found that solar flare eventsaffected the VLF wave propagation in the Earth-ionosphere waveguide by changingthe lower ionosphere electron density height profile, in a different way, fordifferent solar flare events.
