Аннотация:A mobile W-DIMM device was used to measure seeing at the Crimean station of SternbergAstronomical Institute of Moscow State University over seven nights, from June 23 to 30, 2024. Seeingestimates for altitudes greater than 500 m were inferred from scintillations in the sensor apertures separate from the total optical turbulence power. The zenith-adjusted seeing values were βmed ≈ 1.15", the corresponding seeing for the upper atmosphere was found to be of about 0.28". A comparison of the seeing estimates obtained on these nights at telescopes with long exposures agrees well with the readings of the mobile differential image motion monitor. Some climatic parameters were also obtained both from astationary weather station near the observation point and from satellite data.
