摘要

The maximum increase in the phase delay of the JXN radio signal during the solar eclipse on August 11, 2018 was 0.256 radians (09:48 UT) and 0.227 radians (09:56 UT) during VLF registration at Tixie Bay and Yakutsk, respectively. The normalization coefficients relating the effective height changes of the Earth-ionosphere waveguide and the logarithm of the ratio of the solar radiation flux during the eclipse to the total radiation flux for the daytime are 3.43 ± 0.21 and 2.23 ± 0.09 km for the JXN - Tixie Bay and JXN - Yakutsk radio paths respectively. According to our estimates for the segment of the JXN - Tixie Bay path (75° N, 113° E, a local maximum eclipse at 09:43:48 UT, the linear phase Φ = 0.628) the maximum increase of the effective height of the Earth-ionosphere waveguide was 2.28 km. For the segment of the JXN - Yakutsk path (70° N, 113° E, a local maximum eclipse at 09:56:24 UT, the linear phase Φ = 0.627) the maximum increase of the effective height of the Earth-ionosphere waveguide was 1.47 km. At the partial reflection radar of the PGI (69.0° N, 35.7° E) the eclipse was just before local noon when electron density of the lower ionosphere increased and the effect of a relatively weak solar eclipse was not detected (the maximum of the eclipse linear phase Φ = 0.313 at 09:27 UT).
