On July 11, 2020, at 5 am, Professor Oleg Belkovich passed away after a long illness.

Oleg Belkovich was born in Kazan, into a family of  an astronomer. His father, Igor Vladimirovich Belkovich, world-renowned researcher of the Moon, worked in Engelgardt Astronomical Observatory (EAO), situated in a forest, 20 km from Kazan, from 1928 until his death in 1949.  Oleg graduated from Kazan State University (KSU) in 1957, as a radio physicist. His first work was as an engineer in a radio astronomical laboratory in KSU. In 1964, he got his first scientific degree (candidate of science — an equivalent of PhD). From 1965 to 1970, Oleg worked as an assistant and assistant professor in the radio astronomy department at KSU. In the years 1966 – 1967, he completed a scientific internship in England, at the University of Sheffield, working with the famous meteor researcher Professor T. R. Kaiser.

In 1970, Oleg transferred to work in the EAO as a deputy director for scientific work; at the same time, he served as the head of the meteor department. In 1977 – 1991, he served as director of the EAO. As director of an observatory he had to deal not only with scientific, but also with organizational and economic work. The astronomical observatory is an autonomous institution in which the director is obliged to ensure not only the coordination of scientific research, but also comfortable living conditions on its territory for more than 150 scientists and members of their families. Nevertheless, he found time to defend his second scientific degree (D. of Sci.) in 1988.

In 1991, Oleg resigned to devote most of his time to science, and had a position of principal researcher. He was also a professor at Kazan University for almost two decades (1996 – 2014). Oleg was a member of the International Astronomical Union from1966, and in 1982 he was elected as President of Commission 22 IAU for the following triennium.

As a professional astronomer, Oleg Belkovich had been focusing on the study of radar observations of meteors. He began with the development and improvement of equipment for radar observations of meteors and took a direct part in the observations. The work started originally as military research on communications via meteors, but later evolved into the study of radar meteors themselves. Later Oleg became more involved with theoretical work regarding the interpretation of radar observations. Oleg proposed a new, probability-based approach to processing and interpreting the radar observations of meteors. For the first time in the world, he obtained the distribution of the amplitudes and durations of meteor echoes in an analytical form, considering the random positions of the reflecting points on the meteor trails. The method allows calculation of the incident flux density for a meteor shower, which is one of the basic problems of meteor astronomy. Asteroid 179595 Belkovich (2002 MK4) is named in his honor for his work in radar observations of meteors.

It would not be an exaggeration to say that Oleg Belkovich was an eminent meteor astronomer. Some of his numerous students are now doctors and professors and continue his work in astronomy. He always had time for collaboration with amateur meteor astronomers, highly appreciating the scientific value of their efforts. In 1994, he organized the Meteor Summer School in EAO, inviting several amateur astronomers from Europe to participate. In co-authorship with amateur meteor astronomers from Crimea, he published research papers in WGN (journal of the International Meteor Organization, IMO), and participated in several annual International Meteor Conferences, organized by IMO.  In 2005, IMO organized a Radio Meteor School in Oostmalle, Belgium, where Oleg, being the main invited lecturer, presented a series of lectures covering his theoretical work on radio meteors. For five days participants, listened to lectures, alternated with “study time” and Q&A sessions. As a result, the 130-pages volume of RMS2005 Proceedings appeared. At this occasion Olech was nominated as IMO honorary member.

Until the end of his life Oleg lived and worked in EAO, and here he was buried. He found his peace, and we lost a teacher, colleague, friend and just a good man.
