In 2020, the Astronomical Observatory had 58 employees, of which 48 full-time and 10 part-time, scientists – 34 (6 doctors of sciences and 17 candidates of sciences). During the year, 4 budget and 3 contractual topics were implemented. The main scientific results. A method for calculating the local characteristics of the lens reflection in the vicinity of critical curves has been developed. Sequential analysis of local characteristics of the microlensing process with such a degree of detail was performed for the first time. The result is important for the analysis of events with significant amplification in extragalactic gravitational-lens systems. As a result of complex studies of small bodies of the solar system, the properties of the dust and gas atmosphere of the studied active objects are diagnosed by numerical modeling and the relationship between physical and dynamic characteristics of objects of different populations. The modernization of the observation base of the university in the village of Foresters – a new CCD camera for the AZT-8 telescope has been purchased, and a mobile complex for observing the phenomena of star coverage by asteroids has been created on the basis of the acquired Celestron telescope and Atik Infinity series CCD cameras. According to observations with the solar photometer of the international network AERONET, new data on the content and characteristics of aerosol particles in the atmospheric column over Kiev during 2019 – 2021, identified and evaluated seasonal and interannual variations in spectral optical thickness of the aerosol component and its impact on energy balance Kyiv for 12 years of continuous observations. According to the research results, 1 monograph, 68 scientific articles were published, 76 reports were made at scientific conferences.
