The turbulence study in the astronomical observatory in the North Caucasus

Abstract

In the Special Astrophysical Observatory (SAO) continued pilot studies and research astroclimate coherent turbulence, similar to those given by us to the CAO in October 2012. To this end, under the dome of the Big Telescope Altazimuthal (BTA) has been measured astroclimate parameters. Measurements made throughout the volume of the dome of the specialized facilities BTA using ultrasonic weather station AMC-03 is fastened to the structure of the rotating telescope and dome. Also construction of temperature measurements of the telescope and the dome (and their size) used a thermometer and a laser rangefinder.Along with the state of the atmosphere measurements dome of the telescope is controlled ultrasonic meteosystems Meteo-2, mounted on 20-meter meteorological mast at the telescope site. Meteo-2 was used for the registration of long-term observations of atmospheric turbulence parameters for the expedition in order to clarify the conditions of the emergence of coherent areas of turbulence over the observatory territory.
