Airglow variations in emissions of atomic oxygen OI 557.7 and OI 630 nm and NaI 589.0-589.6 nm lines in Eastern Siberia after the fall of Chelyabinsk meteor on February 15, 2013, are studied. During the first nights, we noted certain features of OI 557.7 nm, OI 630 nm, and NaI 589.0-589.6 nm emissions related to changes in the night mean intensities (decrease in the OI 557.7 nm emission and increase in the NaI 589.0-589.6 nm emission) and night variations in these emissions. During the next month after the fall of the Chelyabinsk meteor, intervals were found with increasing intensities of OI 557.7 nm and NaI 589.0-589.6 nm emissions as compared to preceding periods. The nature of some noted features of variations in the OI 557.7 nm, OI 630 nm, and NaI 589.0-589.6 nm emissions does not exclude their possible connection with the Chelyabinsk meteor event.
