Аннотация

The night-time seeing measurements obtained with the ESO Differential Image Motion Monitor at Mt. Maidanak from August 1996, up to June 1999 are presented. This instrument was also used for seeing estimation at La Silla and Paranal Observatories in Chile in 1988 - 1996. The median value of seeing--(beta) <SUB>FWHM</SUB> (the full width at half maximum of a long-exposure stellar image at zenith at (lambda) equals 500 nm) for the entire period of observations is 0.69 arcsec. For the La Silla and Paranal Observatories, this parameter is 0.87 and 0.66 arcsec, respectively.
