Description	The preliminary results of the comet surface photometry performed in the framework of the small bodies programme of the Klet Observatory are discussed. The integrated brightness of the tail of comet 122P/de Vico has been used for the determination of the dust flow characteristics in the tail. It is shown, that in the dusty tail near coma, where the contribution of small %22fluffy%22 and unstable dust particles to the surface brightness of the tail is substantial, the decrease of integrated brightness with distance indicates effects of some kind of disintegration mechanism. The apparent lifetime of grains inferred from the tail photometry is less than one day at the heliocentric distance 1 AU. This effect might be caused either by sublimation or by electrostatic charge disruption of grains, and even the albedo change should be considered. Since the narrow streams are presented on the tail images of 122P/de Vico obtained with a R filter, a substantial contribution of the ionized molecular species must b The preliminary results of the comet surface photometry performed in the framework of the small bodies programme of the Klet Observatory are discussed.
