Abstract

The observatory Lovozero (68.0N, 35.0E, Polar Geophysical Institute) carries out regular observations of aurora. During the aurora observations in some cases the luminescence of the night sky had a wavy structure with the wavelengths of several tens kilometers and with the temporary periods about 15-30 minutes. For two cases comparisons with data of the radar of partial reflections in the observatory Tumanny have been carried out. Maxima of reflection amplitudes of the radar took place at the heights of 80-90 km and amplitudes at these heights had the periods similar to the periods of fluctuations of luminous intensity of the sky. It allows assuming that the wave structures in the luminescence were caused by acoustic-gravity waves.
