Abstract: 

Ionosonde data for the March 20, 2015 solar eclipse period acquired over Europe have been used to analyze ionospheric disturbances near 300-km altitude. The analysis has established that the eclipse was associated with the generation of gravity waves and traveling ionospheric disturbances. The latter waves had periods of 30—100 min and 4—19 % amplitudes of disturbances in the electron density on a relative scale. The disturbances lasted no shorter than two hours. During the eclipse, the disturbance amplitude more often exhibited an increase, while in oner case, a decrease that resulted from suppressing waves that existed prior to the eclipse by waves generated by the eclipse.
Keywords: disturbances, ionosphere, solar eclipse
