Subject and Purpose. This work examines eff ects of the November 3, 2013 solar eclipse, in particular the atypical increases in the level of radio interference and scintillations of the radio sources 3C 123 and Cas-A that were observed at 25 MHz. These phenomena might owe to the enhanced wave activity in the ionosphere during the eclipse and a reduced radio wave absorption. Methods and Methodology. The observations were conducted with the use of the low-frequency radio telescope URAN-4 (operativ
