V. D. Tereshchenko et al. Fig. 1. The solar eclipse above Murmansk on 1 June 2011. 4. Results of measurements and the analysis In Figure 2 changes of solar zenith angles during the eclipse and riometric records at Tumanny are shown. The period of the eclipse is marked by three continuous vertical lines. UT.hrs UT, his Fig. 2. Change of zenith angles and intensity of space noise emission on the frequency of 32 MHz on 1 June 2011. Results of measurements by the method of partial reflections are submitted in Figures 3 and 4. The continuous curve shows change of riometric absorption.
