Paper Abstract

Based on the results of repeated measurements of under dome airstreams parameters of the AZT-33 telescope, some conclusions have been drawn, allowing improvement in quality of astronomic images in the telescope. After fulfillment of a part of recommended works, changes of under dome climate were compared with the measurements of 2005. New measurements verify the results obtained in 2005. Mixing of warm and cold air is observed inside the telescope after dome opening as well as one-order-of-magnitude increase of turbulence intensity in front of the input telescope mirror after dome opening. A changed pattern of under dome airstreams has been constructed. Further measures on qualitative thermal insulation of the under dome room are recommended. Astronomic observations are to be carried out only after ending of transient processes concerned with dome opening.
