Paper Abstract

On November 16, 2017 at 16:40:22 UT over Northern Finland a powerful meteor explosion had occurred. Entry of the meteor was recorded by the all sky camera at the radio physical observatory Verkhnetulomsky (68.59°N, 31.75°E), and response of the high-latitude lower ionosphere to this explosion was recorded by the radar of the partial reflections at the radio physical observatory Tumanny (69.0°N, 35.7°E). After the explosion the considerable disturbances in the ordinary wave amplitude at the heights of 80-95 km have appeared. Using the temporal variations of the ordinary wave amplitude the periods corresponding to resonant atmospheric modes were identified: the acoustic cut-off period and the BruntVäisälä period, and also temperature of the atmosphere and sonic speed at the mesopause heights were calculated. It was suggested that the disturbances could be caused by the waves which had magnetohydrodynamic nature.
