Abstract

During the launch of the Soyuz rocket on December 18, 2020 at 15:26 Moscow time from the Vostochny cosmodrome, we carried out observations on a monochromatic all-sky imager at the Maimaga optical station. A KeoSentry camera with interference filters at 630.0 557.7 and 620.0 nm (continuum) was used for observations. The shooting mode was set with an exposure of 20 seconds with a full revolution of all filters in 1 minute. Thin clouds were noted during the observations. During the flight of the zenith rocket of the Maimaga station on the 630.0 nm channel, a luminous strip was registered along the flight path. Moreover, this glow was not observed on other channels. The intensity of this band at the zenith was ~ 25 Rayleighs. This strip existed for about 30 minutes until it was completely blown away by the wind from the camera's field of view to the east. According to estimates of the strip drift, the wind speed at the glow height was ~ 130 m/s. The diffusion rate was ~ 250 m/s.
