- Аннотация: Reaction of the high-altitude lower ionosphere and the geomagnetic field to explosion of the Vilyuysk meteoroid according to the medium wave facility of partial reflections located on the radio physical observatory “Tumanny” (69.0°N, 35.7°E) of Polar geophysical institute, and observatory “Lovozero” (68.0°N, 35.0°E) is considered. The meteor has blown up on 5 March 2014 at 7:29 the Yakut time (on 4 March, 21:29 UT) in the sky over the Vilyuysk district of Yakutia (64.3°N, 123.1°E). For the analysis amplitudes of ordinary and extraordinary waves, received by the radar of partial reflections, and variations of the geomagnetic field of observatory “Lovozero” have been considered. It is shown that the explosion has caused changes in the ionosphere and the geomagnetic field, and also emergence of waves of different types: internal gravity waves and slow magnetohydrodynamic waves.
