Observation of Optical Flashes of the Night Star Sky on the Atmospheric   Cherenkov Installation Tunka-13
  Experiment on the study of fluctuation of night glow is conducted on the base of 13 module atmospheric Cherenkov telescope TUNKA-13.Basic task of TUNKA-13 is registration of light from Extended Air Shower (EAS) initiated by primary cosmic particles. Observation of light flashes radiating in nigght atmosphere is one more experiment which is run for TUNKA-13 to study the background condition for EAS registration. At a period from December 1997 on a May 1998 was registered 149 light flashes of radiwting night atmosphere with duration from 16 ms to 190 seconds. General time of night observing has formed 237 hours. Coincidence of optical flashes with the gamma-bursts from the catalogue of BATSE experiment of observatories "Compton" was analysed.
