Abstract

Research of atmospheric gravitational waves on the observations of noctilucent clouds in the city of Yakutsk in the summer season of 2018 was carried out. The observations were made using a permanently installed Samsung Galaxy S4 / mini phone using the free program Time Lapse Creator. The shooting was carried out with an exposure of 2 seconds, every 2 minutes in the direction above the northern horizon. The rare case of observing such a wave structure of noctilucent clouds on July 26, when several waves of different lengths and intersecting directions of propagation are simultaneously observed, is analyzed. The main characteristics of the analysis of these gravitaty waves are given.
