The astroclimate of Maidanak Observatory in Uzbekistan [PDF]

open access: bronzeAstronomy and Astrophysics Supplement Series, 2000
The atmospheric turbulence and meteorology of the Maidanak Observatory in Uzbekistan are reviewed. Night time seeing was measured during the period August 1996 - November 1999 with the ESO Dierential Image Motion Monitor. The median zenith seeing (FWHM) for the entire period of observations is 0.69 00 at 0.5 m.
