History of the Institute
The Astronomical Observatory was founded on 3 August 1871 (15 August 1871 in the Gregorian calendar) as a component unit of Imperial Novorossiya University. It was first directed by Professor Leopold F. Berkevich, the Head of the Department of Astronomy of the University, an expert in meteorology and celestial mechanics; under his directorship, the Observatory staff made expeditionary observations of the transit of Mercury across the disc of the Sun, and performed a series of other studies.
The astrophysical focus of the Observatory’s research activities was narrowed by Aleksandr K. Kononovich, who was in charge in 1881-1912. The name of the next Director of the Observatory, Aleksandr Ya. Orlov, an Academician of the Academy of Sciences of Ukraine, a Corresponding Member of the Academy of Sciences of the USSR, who held the position in 1913-1933, was associated with numerous initiatives and further evolution of the Observatory as a large scientific institution in the South of Ukraine.
Since the University was disbanded in 1920, the Observatory’s status changed to Odesa State Astronomical Observatory of the People's Commissariat for Education of Ukraine up to 1933. In 1933, with the re-establishment of Odesa State University, the Observatory again became a part of it. A new Director, Professor Konstantin D. Pokrovskiy, a Corresponding Member of the Academy of Sciences of the USSR, was in charge of the Observatory in 1934-1944.
From 1945 to 1983, the Observatory was headed by Professor Volodymyr P. Tsesevich, a Corresponding Member of the Academy of Sciences of the Ukrainian SSR, an Honoured Scientist and Engineer of Ukraine. Under his directorship, the Observatory built two observing stations away from the city – in Kryzhanivka and Mayaky villages, as well as three high-mountain stations in Armenia, North Caucasus and Turkmenia, respectively; moreover, the Observatory gained its status as a 2nd category scientific institution, while its scientific staff enlarged from 15 to almost 100 employees. In 1957-1960, the Observatory was reckoned as the main observatory in the USSR for studying meteor events (under the leadership of E. N. Kramer); it was assigned by the International Astronomical Union to investigate variable stars within three specified tasks (which was performed by Yu. S. Romanov, K. M. Makarenko, O. Yu. Mandel and others). The respective research was conducted, and meaningful fundamental and applied results were obtained; meanwhile, the institution purchased a KT-50 telescope for satellite observations made at Krasnogorsk Mechanical Factory; the Observatory was also equipped with a new reflecting Azimuth Star Telescope, AZT-3, manufactured by the LOMO factory, a number of self-manufactured telescopes (with mirrors of 20 to 80 cm in diameter) and advanced surveillance instruments and devices.
Alumni of Odesa Astronomical Observatory include notable scientists who worked at the Observatory in 20th century – namely, V. K. Abalakin, V. A. Albitsky, Z. M. Aksentieva, I. S. Astapovich, A. S. Vasilyev, J. J. Witkowski, G. A. Gamov, A. P. Hansky, V. M. Grigorevsky, N. B. Divari, V. S. Zhardetsky, N. S. Komarov, E. N. Kramer, B. V. Novopashenny, K. M. Savchenko, N. M. Stoyko-Radilenko, V. V. Stratonov and many others.
Yu. A. Medvedev, PhD/CandSc in Physics and Mathematics, was appointed as Director in 1983-1989 and also headed the Department of Cosmic Research of the Observatory. During that time, the Observatory conducted contract-based studies on the cosmic and other astronomical topics; it also managed to purchase a 100-cm laser ranging theodolite TPL-1M. The number of the Observatory staff members and contract-based researchers exceeded 150 employees.
From 1990 to 2006, the Observatory was directed by Professor Valentyn G. Karetnikov, DSc in Physics and Mathematics, who also headed the Department of Astronomy of the University. In 1993, the Observatory gained its status as a 1st category scientific research institution at Odesa State University (along with the rights of a legal entity), having reserved its legal name “Astronomical Observatory”.
During 1990s and early 2000s, the total number of the Observatory staff members constantly reduced whereas the number of employees with doctoral degrees increased. All observations and calculations were computerised. AZT-3 and a 60-cm telescope, equipped with an analogue TV camera, were employed at the observing station in Mayaky village; an 80-cm telescope with a two-channel electro-photometer still operated in Turkmenia; in Odesa, the high-speed satellite tracking telescope KT-50, equipped with a CCD TV camera, was given a new lease of life, while a self-manufactured telescope with a primary mirror of 1 m in diameter, furnished with a two-channel electro-photometer, was installed and operated in Humenné (Slovakia) under agreement with Vihorlat Observatory.
In 2006, Professor Sergiy M. Andrievsky, DSc in Physics and Mathematics, was appointed to head the Observatory, as well as the Department of Astronomy. However, later on, the Department of Astronomy was integrated into the Department of Theoretical Physics of the Faculty of Physics of Odesa I. I. Mechnikov National University. And after a while, when the Faculties of Mathematics and Physics merged together, a single Department of Physics and Astronomy was created.
During the 2000s, the SRI “Astronomical Observatory” has continued performing tasks addressing the topics of state-funded competitive research grants and several contract-based research projects. It is owing to the sponsorship and personal participation in the works by an alumnus of the Department of Astronomy of Odesa I. I. Mechnikov National University and former employee of the Observatory, Vadym V. Zhukov, that a multifunctional automated telescope OMT-800 (with a primary mirror of 800 mm in diameter) was placed in operation, having been restored to full working order and furnished with state-of-the-art equipment. Thanks to collaboration with Shanghai Astronomical Observatory, a high-speed satellite tracking telescope KTC was automated and installed at the observing station in Mayaky village. The TV Meteor Patrol keeps working at the observing station in Kryzhanivka village. Constructing and putting in operation a digital Planetarium of the University at the territory of the Observatory is a result of intense efforts of the Head of Odesa Astronomical Society, Mykhailo I. Riabov (PhD/CandSc in Physics and Mathematics, a staff member of Odesa Observatory of the Institute of Radio Astronomy of the National Academy of Sciences of Ukraine), sponsors’ financial support and collaboration with local authorities in Odesa city.
In the second half of the 20th century, an extensive collection consisting of more than 100 thousands of photographic plates with captured images of the starry night sky, reckoned as the 3rd largest in the world, was accumulated at Odesa Observatory; in the 21st century, the collection became a significant contribution of the Observatory to the Virtual Astronomical Observatory of Ukraine. The collection of the Astronomical Observatory Scientific Library includes over 200 thousands items.
In early 2021, the state funding reduced dramatically, which was catastrophic for the Observatory thus compelling to fire almost 90 per cent of the staff employees. Later, the situation with financing slightly improved – as a result of competitions for research projects arranged by the Ministry of Education and Science of Ukraine, the Observatory obtained funding which enabled to enlarge the number of staff members up to 14 employees. In 2023, the Observatory has been executing research within two state-funded projects under supervision of two Doctors of Sciences in Physics and Mathematics, namely Valery V. Kovtyukh and Tamara V. Mishenina.
In September 2021, the Educational and Scientific Centre for Educational Programmes “Astronomical Observatory” was created as per the Order of the Rector of Odesa I. I. Mechnikov National University; consequently, salaries were allocated for the positions of the Director of the Observatory and three full-time specialists acting as Heads of the suburb observing stations and authorised as responsible for material assets. The Head of the Department of Cosmic Research, Mykola I. Koshkin, PhD/CandSc in Physics and Mathematics, was appointed as Director of the ESC “Astronomical Observatory”.
Scientific research lines
A scientific school entitled “Odesa Scientific Astronomical School” was established at the SRI “Astronomical Observatory” as early as in the 20th century. Professors Volodymyr P. Tsesevich and Valentyn G. Karetnikov were academic supervisors of the School; today, it is nominally headed by Professor Sergiy M. Andrievsky. The scientific research conducted at the SRI “Astronomical Observatory” focuses on a variety of objects and covers a wide range of scientific issues; these include studying the chemical evolution of matter in the Universe as a whole, and in particular in the Milky Way; the problems of dark energy and dark matter; the near-Earth space monitoring and other related issues.
The scientific research lines have been historically developed as follows:

Main scientific findings and research results
For the first time, abundances of elements from lithium to europium were analysed in the sampled stars (about 200 disc dwarf stars with or without planets). Deficiencies in lithium and barium, along with aluminium overabundances, were detected in planet-hosting dwarf stars. Based on lithium abundance determinations in 280 stars, the relationship between superflares and content of lithium was analysed for the first time; it was also illustrated that high lithium abundances were associated with the saturation of stellar activity.
It was first demonstrated that the distribution of lithium abundances in solar twins could be mainly attributed to the dependence of the lithium content on the age of stars, that is, abundance variations due to stellar evolution. The results were consistent with theories considering rotationally induced mixing of stellar matter. It was found out that for dwarf stars there was a certain value of the effective temperature at which the pattern of their surface activity changed. Yttrium and barium abundances were determined for stars in open clusters.
A correlation between the yttrium abundance and galactic distance similar to that one measured using Cepheids was found for young clusters; it confirmed the existence of radial yttrium abundance gradient in the Galactic disc. Correlations of yttrium and lanthanum abundances with the age of stars were established based on the studies of abundances of barium and other elements in stars of open and globular clusters belonging to different Galactic substructures. Correlations obtained for stars in open clusters turned out to be similar to those for thin disc stars, which suggested similar origin of stars in the Galactic thin disc and open clusters. A new source of barium production was proposed, namely the i-process neutron capture.
Abundances of strontium, molybdenum and ruthenium were determined in about 300 Galactic disc stars. It was first confirmed that contributions of the s-process in AGB and massive stars were the main sources of strontium in the Galactic disc and in the Sun, while different sources of nucleosynthesis could account for high abundance ratios [Sr/Ba] and [Sr/Eu] observed in the early Galaxy.
For the first time, it was shown that using four Galactic Chemical Evolution (GCE) codes, the proposed additional contribution to the molybdenum enrichment by SNe Ia improved the reproduction of its behaviour by modern GCE theoretical calculations at solar metallicities; however, the molybdenum and ruthenium underproduction as compared to the observed values was still observed at all metallicities. Molybdenum abundances were first determined for stars in 13 clusters. A comparison of the molybdenum behaviour in stars of open clusters and those of the Galactic disc exhibited similar trends of decreasing molybdenum content with increasing [Fe/H]; such a model of the Mb abundance behaviour suggested similar origin of the examined stellar populations. The relationship of the molybdenum abundance with the age of stars and distances from the Galactic centre was analysed. A comparison with the behaviour of the s- and r-process elements revealed the existence of an alternative source of the molybdenum enrichment. It could be either the i-process or proton-capture processes. It required considering or re-calculating processes of nucleosynthesis which had not yet been taken into account in modern simulation.
For the first time, in order to find “chemical fingerprints” in stellar atmospheres, chemical characteristics of 12 stars with confirmed planets were investigated based on homogeneous spectral data, including lithium, carbon, oxygen, magnesium and silicon abundances and their ratios; the results could help to choose between two main theories of planetary origin – namely, protoplanetary disc accretion and planetesimals falling off.
Manganese and sulphur abundances in atmospheres of dwarf stars in the Galactic thin and thick discs and the Hercules stream were determined. It was detected that the manganese abundance increased with increasing metallicity, which confirmed the basic scenario that the greater part of manganese in the Galactic disc and in the Sun originated in thermonuclear supernovae; alternative sources of production were analysed and employed.
A study of the Galactic disc enrichment with neutron-capture elements, such as Gd, Dy and Th, was conducted. New observational data, along with the europium (Eu, Z=63) data from earlier studies, were compared with the nucleosynthesis predictions and GCE simulations. It was confirmed that the behaviour of gadolinium and dysprosium was similar to that of europium. However, the production of thorium, unlike europium, was metallicity dependent in the case of a unique source of the r-process in the Galaxy; otherwise, the frequency of a thorium-rich r-process source decreased with increasing metallicity.
Stellar parameters, as well as abundances of elements from Li to Eu, were obtained for 25 stars hosting massive planets. The content of iron [Fe/H] and key elements (Li, C, O, Mg and Si) that indicated the planet formation, as well as correlations between [El/Fe] and condensation temperature, Tcond, were analysed. Iron abundances estimated in the sampled stars with detected massive planets ranged within -0.3 < [Fe/H] < 0.4. The behaviour of [C/Fe], [O/Fe], [Mg/Fe] and [Si/Fe] with [Fe/H] was consistent with GCE trends. The mean values of C/O and [C/O] were slightly lower than the solar ones. The ratio Mg/Si varied from 0.83 to 0.95 in four stars of the sample and from 1.0 to 1.86 in the other 21 stars. For the first time, different slopes of [El/Fe] vs. Tcond were found. Correlations of the planetary mass with metallicity, lithium abundance, C/O and Mg/Si ratios, as well as [El/Fe] vs. Tcond slopes, were first considered for the investigated stars.
The dispersion of lithium in the atmospheres of 56 solar-type stars, including 22 solar twins, was analysed for the first time. The lithium abundance was obtained by comparing observed and synthetic spectra in the Li I 6707 Å line region, taking into account NLTE corrections. The Li abundance scatter observed in solar twins was considered as a function of age, rotational velocity and other factors. A comparison of predictions of stellar evolution models which factored in various processes of angular momentum transport, as well as chemical elements’ transport was conducted (T. V. Mishenina, T. I. Gorbaneva, V. V. Kovtyukh and S. A. Korotin).
Actinium abundances in three red supergiants in the Small Magellanic Cloud, thorium abundances in Cepheids in Magellanic Clouds, and abundances of heavy elements in the star BL138 belonging to the Fornax dwarf spheroidal galaxy were determined for the first time. It was demonstrated that the accretion of the surrounding gas onto the surface of stars in the Small Magellanic Cloud with high spatial velocities was possible (V. F. Gopka and V. O. Yushchenko).
A direct analysis of carbon and nitrogen lines in the spectra of nine RR Lyrae stars using the synthetic spectrum method under non-LTE conditions was performed for the first time. It was first concluded that the observed abundances could be attributed to the first dredge-up which had occurred in the previous red-giant phase and during which partially CNO-processed material had been transported onto the stellar surface (S. M. Andrievsky and V. V. Kovtyukh).
For the first time, a series of high-resolution Very Large Telescope (VLT) spectra was obtained in order to calibrate the radial velocity zero point of the Radial Velocity Spectrometer (RVS) on board the ESA Gaia satellite. Moreover, the chemical analysis of the respective 80 stars was first conducted. Two new super lithium-rich Cepheids, with a high lithium abundance А(Li) = 2.94±0.09 dex – namely, ASAS 075842-2536.1 and ASAS 131714-6605.0 – were discovered. As a result of the discovery, the number of known super lithium-rich Cepheids in the Milky Way increased to five, three of which were discovered at the SRI “Astronomical Observatory” of Odesa I. I. Mechnikov National University (V. V. Kovtyukh).
The chemical composition of four classic Cepheids in the Galactic nucleus was examined for the first time. An advanced self-developed method for determination of the effective temperature of programme stars, based on the calibration ratios between temperature and spectral line depths, was employed. The results obtained recently have confirmed an earlier discovery about roughly solar metallicity in the Galactic Centre (V. V. Kovtyukh and S. M. Andrievsky). It was shown for the first time that classical Cepheids could be used to trace spiral arms even at far distances from the Sun. To that end, the existing distortion (warp) of the Galactic disc was first used. For the first time, a detailed chemical composition (including 25 elements) of 105 classical Cepheids was determined using spectra obtained with the Southern African Large Telescope (SALT) with a primary mirror of 11 m in diameter. Rather significant azimuthal variations in the oxygen abundance [O/H] were first detected. It substantiated similar conclusions for the nearest spiral galaxies, as well as recent 2D chemodynamical models of our Galaxy (V. V. Kovtyukh and I. O. Usenko).
The emission in the He I infrared (IR) triplet line at the wavelength 10 830 Å in the classical Cepheid X Cyg was detected for the first time. It was the first detection of the IR emission of helium in classical Cepheids. For the first time, it was demonstrated that the interplay of charge-exchange reactions due to the accretion of interstellar matter or the gas-dust separation mechanism could affect the initial abundances and could be used to qualitatively explain the patterns of overabundances in some elements in the atmosphere of the planet-hosting star HD 47536 (V. V. Kovtyukh and S. M. Andrievsky). A new scenario to account for the phenomenon of Przybylski's star (HD 101065) was proposed. It was based on the supposition that Przybylski's star was a component of a binary system containing a neutron star (S. M. Andrievsky and V. V. Kovtyukh).
Photometric observations of variable stars, asteroids and nuclei of active galaxies were performed using the AZT-3 telescope (at the observing station of Odesa I. I. Mechnikov National University in Mayaky village). The results obtained in studies of RR Lyrae variables were published subsequently, in particular detailed light curves at different phases of the Blazhko cycle and the Blazhko periods. Periodic variations in brightness just before and at the end of each outburst were recorded in SU UMa dwarf novae (S. M. Udovichenko, L. E. Keir and others). Detailed light curves were obtained for active radio galaxies, namely blazars OJ 287, 3C371, Mrk421, Mrk501 and 3С84; along with radio observations, it made it possible to detect short- and long-term periodic variations in brightness associated with the accretion of matter into the black hole (S. M. Udovichenko, L. E. Keir, A. L. Sukharev, M. I. Riabov and others).
Light curves were obtained for Vesta family asteroids; together with observation results reported by other authors, it enabled to determine their spin rates (V. V. Troianskyi, V. I. Kashuba, S. M. Udovichenko, L. E. Keir and others).
Three-dimensional hydrodynamic computations of the formation of a gaseous envelope around β Lyrae were performed taking into account all known observational facts which could have an impact on that process, such as mass transfer through the first Lagrangian point (L1) and mass loss due stellar winds from the accretor and the mass donor. It yielded a model not just qualitatively, but also quantitatively similar to modern views about the complex structure of the gaseous envelope surrounding β Lyrae formed on the basis of numerous observations at all wavelength ranges via various methods and techniques.
Three-dimensional numerical hydrodynamic simulation of the radiation-driven jet launching and disappearing in the off state, and also modelling of flares in close binary systems (CBS) were carried out for the Cyg X-1 close binary system taken as an example. It was demonstrated that owing to the mass transfer instability, the flare generation mechanism could reproduce quite realistically flares in CBS (V. V. Nazarenko and S. V. Nazarenko).
For the first time, parameters of eclipsing binary systems 2MASS J11080308-6145589 and GSC 3692-00624 were obtained. Mathematical-phenomenological models of eclipsing binary stars of different types were developed (I. L. Andronov and L. L. Chinarova).
It was first shown that multidimensional Kaluza-Klein gravitational models with different types of compactification of the internal space did not contradict famous gravitational tests in the Solar System if the gravitating masses were uniformly smeared over the internal space, having negative pressure (i.e. tension) in those dimensions. The findings were published in a series of articles in leading foreign journals. A new approach to studying multiscale structure of the Universe was proposed for the first time. Within that approach, dubbed “the cosmic screening”, scalar and vector perturbations of metric coefficients were considered. As a result, an accurate analysis of linearized Einstein’s equations demonstrated that gravitational potentials of gravitating masses were subject to an exponential cut-off at far (of the order of 2-3 gigaparsecs) distances. It was a pure relativistic effect associated with the non-linearity of Einstein’s equations. The energy-momentum tensor, being a source of the gravitational field, itself depended on the gravitational field. The cosmic screening effect was substantiated by numerical simulation using the supercomputer at Istanbul Technical University. Power spectra for scalar and vector metric perturbations, as well as mass density contrasts, were obtained. It was also demonstrated that a computer code based on the simplified Einstein’s equations within the cosmic screening approach was 40% more efficient than the known N-body relativistic code “Gevolution”, thus making it possible to significantly save expensive computational time on supercomputers (A. I. Zhuk, M. V. Eingorn, A. V. Chopovsky, M. D. Brilenkov, R. D. Brilenkov and M. V. Burgazli).
New original observations of artificial and natural cosmic objects in near-Earth space, whose photometric and dynamic parameters were included in the relevant astronomical databases, were conducted. Based on high-frequency photometric observations, high-time-precision data were obtained and spin parameters of a number of artificial satellites, in particular experimental geodetic satellite “Ajisai”, were calculated. An optical-geometric model of Ajisai was computed and used to analyse variations in the satellite spin rate and causes of such spinning instability; that was essential for building the theory of free rotation of many other near-Earth bodies. A number of methods and techniques that enable the monitoring slow changes in the spatial orientation and the nature of rotation of various satellites, which sometimes specularly reflect the light off the surface facets, have been developed. Such monitoring makes it possible to determine long-time changes in the inertial rotation period, to update the spin-pole position and track the evolution of the spin parameters due to the YORP-effect. Spin parameters and spatial orientation of a large inactive Earth-observing satellite “Envisat” were obtained, which is necessary for the European Space Agency e.Deorbit mission aimed to remove it from orbit (M. I. Koshkin, L. S. Shakun, O. O. Korobeynikova, S. L. Strakhova, S. M. Melikiants, V. V. Dragomiretsky, A. V. Riabov, S. S. Terpan and others).
A numerical model of orbital motion of artificial near-Earth objects was built using the Orekit a space flight dynamics library; the model factored in high harmonics of the Earth’s gravitational potential, perturbations from the Solar System bodies, ocean and solid Earth tides, atmospheric effects predicted by static and dynamic models (in particular, the Drag Temperature Models – DTM), as well as solar radiation pressure taking into account the Earth’s shadow and relativistic corrections. Based on the Standards of Fundamental Astronomy (SOFA), softwares for the conversion between UTC, TAI and TT time scales and for astrometric transformations of the positions of Earth-orbiting objects with an accuracy of 1 µas were developed. A method to assess co-ordinates of a station based on optical astrometric observations of reference satellites (Doris, ILRS) was developed; it made it possible to estimate systematic corrections to a time scale within 0.1 millisecond and reduce errors in astrometric observations of low-Earth orbit objects to fractions of an arc second (L. S. Shakun).
A model of globally distributed ground-based observing sites was created, suitable for a unified analysis of how such a network ensured continuous tracking of all catalogued cosmic objects. Methods and formulae for assessment of the potential accuracy of predictions of the motion of space objects at various orbits were developed with the use of a generalised model of measurements by the local network of observing sites. Limiting possibilities for the refinement of orbital elements were computed with minimization of the number of required measurements and the use of a priori information (M. I. Koshkin, L. S. Shakun and others).
The Gauss method for determination of preliminary Keplerian elements of small celestial bodies in circumsolar orbits was modified (aiming to improve the method’s reliability). The employment of the modified Gauss’s method yielded preliminary orbits of 34 observed asteroids whereas determination of preliminary Keplerian elements through the classical Gauss method was not feasible for 9 of them. The effect of solar radiation pressure on the orbital evolution of asteroid (minor-planet) moons was studied, taking into account the shadow function. The conditions for the systems, composed of at least two gravitationally-bound asteroids orbiting their common centre-of-mass, to be disrupted by tidal forces of a major planet were determined for the first time. A statistical database of critical approaches of binary and multiple asteroids with major planets was created. Rotation periods of 536 sampled V-type asteroids were analysed. Well determined phase curves were first build for about 20 V-type asteroids (O. A. Bazyey, I. V. Kara and V. V. Troianskyi).
TV images of 3,571 meteors were recorded with the TV Meteor Patrol comprised of a Schmidt telescope and three astrocameras over 2003-2018. Today, the total database of observations contains 15,535 recorded meteor events. The Meteor Patrol of Astronomical Observatory of Odesa I. I. Mechnikov National University makes it possible to carry out regular observations with an angular resolving power of 1 arc second and a time resolution of 20 ms, and record meteor events with an apparent magnitude of up to 12. There are not more than 10 such meteor patrols in the world. Regular pattern of meteor patrolling and a sufficient number of observation nights enable to fill the statistics of meteor events for the search of abnormal meteorites. The Meteor Patrol at the observing station in Mayaky village was supplied with new equipment and provided with software created for recording meteorites. A mobile base station positioned on the azimuth mount, comprising an astrocamera KO-140 and a TV receiver, was built. Reference meteor observations were conducted within a special programme of recording high-altitude (130-180 km) meteors. Parameters of base stations for observations of meteors at very high altitudes were calculated; probabilities of recording such meteors were estimated. The results of meteor observations were processed, thus yielding altitudes, velocities and decelerations of meteoroids. The analysis of the existence of nine meteorite-dropping groups in near-Earth asteroidal orbits, comprising sporadic fireballs from the IAU MDC-2007 database, sporadic meteors from the SonotaCo database, as well as L5, L6 and H4-H6 ordinary chondrites and an ureilite, for which atmospheric and orbital parameters had been obtained from instrumental observations, was performed (Yu. M. Gorbanev, I. I. Kimakovska, S. R. Kimakovsky and V. O. Shestopalov).
At the observing station in Mayaky village, the manufacture of component units for the multifunctional automated telescope OMT-800 with a primary mirror of 800 mm in diameter was accomplished, and the telescope was furnished with state-of-the-art equipment and placed into operation (V. V. Zhukov). A CCD photometer on the AZT-3 telescope was upgraded (in particular, a microprocessor and electronic components were replaced). Special computer programmes were developed to automate observations (ensuring automated change of optical filters and dome rotation). A relay board to control the telescope dome rotation was manufactured and installed at the AZT-3 telescope. A new stand was installed for the telescope electronics and photometer. The renovation of the equipment room was accomplished (V. V. Zhukov, L. E. Keir and S. M. Udovichenko). A set of optics for the future telescope with a wide field of view, including a primary mirror (with a diameter of 0.6 m), the surface of which is a hyperboloid of revolution and a Ross-type two-lens corrector, was manufactured (S.
