Abstract
During the solar eclipse of May 20 - 21, 2012 in Yakutsk VLF radio signal phase variations are recorded. The variations are 0.77 and 0.54 radians for JJY40 and NPM radio stations respectively. By the radio signals phase variations a normalization factor is determined. The normalization coefficients are 3,27 ± 0,08 and 2,27 ± 0,05 km for paths JJY40 - Yakutsk and NPM - Yakutsk respectively. The effective height of the Earth-ionosphere waveguide changing for the maximum shading the path JJY40 - Yakutsk (22:47 UT) is 4.63 km. For the path NPM - Yakutsk the effective height changes in maximum shading (23:52 UT) are 4.25 km.
