Paper Abstract

Effects of a solar eclipse 29.03.06 in signals of VLF radio stations, in intensity of the regular radio noises in the frequency band 0,3-10 kHz, and in quantity atmospherics, accepted in Yakutsk preferentially from the western direction surveyed. The area of the complete lunar shadow consistently shaded a day time part of a line of distribution of radio signals from the western Africa edge up to Altai. Observations were conducted with the help of the multichannel analogue parallel analyzer - registrar (in a frequency band 0,47-8,7 kHz), one point a thunderstorm direct-distance finder (0,3-100 kHz), narrow-sector finding of VLF-noise radiation sources (0,3-10 kHz), the registrar of signals of the VLF radio stations and the broadband registrar of radio noises (0,3-100 kHz). Time sync of the registrar of signals of the VLF radio stations was carried out with the help of GPS-clocks. The effect was observed in signals of radio stations, radio noises and quantity atmospherics from a direction 270º ± 20º, digitized from the north clockwise, at last stage of an eclipse (~11-12 UT) when the lunar shadow approached to a line night terminator and intercrossed a line of distribution of signals. The effect was showed as amplification of signals on ~ 20 % and magnifications of quantity atmospherics on ~ 40 %. The registered effects are similar observed by us earlier for an eclipse 09.03.97.
