Abstract:

We present observation results of the night sky brightness in Eastern Siberia after the Chelyabinsk meteorite fall on February 15, 2013. During the first nights following the Chelyabinsk meteorite fall (February 15/16 and 16/17), diurnal variations in the night sky brightness showed both an increase and a decrease in average night values of the night sky brightness relative to the preceding (background) nights. There was an increase in brightness of the night sky in late February – early March. The increase in brightness of the night sky was not observed in previous years and was atypical for the seasonal variations in intensity of the continuous spectrum of night airglow.

Keywords:

Chelyabinsk meteorite, night sky brightness
