Reaction of the high-latitude lower ionosphere and the geomagnetic field to the Vilyuysk meteoroid explosion according to amplitudes of partially reflected ordinary and extraordinary waves, received by the partial reflection facility of the Tumanny observatory (69.0°N, 35.7°E), and geomagnetic field variations of the Lovozero observatory (68.0°N, 35.0°E) of the Polar Geophysical Institute had been considered. The meteor has blown up at 21:29 UT, 4 March 2014, in the sky over the Vilyuysk district of Yakutia (64.3°N, 123.1°E). It was shown that explosions have caused changes in the ionosphere and the geomagnetic field, and also appearance of waves of different types: internal gravity waves and slow magneto-hydrodynamic waves.
