This paper analyses photographic records of 44 fireball events observed between 1971 and 1984, which are believed to represent falls of meteorites with masses in the range from 0.1 to 11 kg. Median values are presented for 20 parameters describing the atmospheric behavior and orbital elements of the fireballs along with correlations found among various parameters. A correlation is suggested of the fireball brightness with the initial meteorite mass and the slope of its trajectory. Moderate correlations were also found of the initial mass with the end height and the duration of luminosity and of the initial velocity with the beginning height, the fraction of the mass that survives as the largest fragment, and the perihelion distance of the orbit.
