Abstract
Observation results of the night sky brightness in Eastern Siberia after the Chelyabinsk meteor event on February 15, 2013, are presented. During the first nights after the Chelyabinsk meteor fall (February 15/16 and 16/17), diurnal variations in the night sky brightness showed both an increase and decrease in the nighttime average values of night sky brightness relative to the preceding (background) nights. An increase in the night sky brightness was observed in late February–early March. No increase in the night sky brightness was observed in previous years; it is atypical for seasonal variations in the intensity of the continuous night airglow spectrum.
