Obituary:

Voloshchuk Yuri Ivanovich (Nov 21, 1941, Lugansk, Ukraine – Aug 26, 2019, Kharkiv, Ukraine) was a well-known Soviet and Ukrainian scientist in field of meteor radio astronomy and small bodies of the Solar system, a former scientific head of the Research Laboratory of Radio Astronomy named after B.L. Kashcheyev and a professor at the Kharkiv National University of Radio Electronics (KhNURE) passed away in Kharkiv (Ukraine) on August 26, 2019, at the age of 77.

Voloshchuk Yu.I. has made valuable contributions to the development of science and education at the KhNURE and is especially known for his research of meteors and interrelated small bodies in the Solar system. Having brilliant knowledge in radio engineering, cybernetics and astronomy, he managed to combine them and apply symbiosis in his scientific research. He developed a proprietary methodology for selecting streams and associations from a large sample of individual meteor orbits, which allowed the creation of the KhNURE database of 5160 meteor showers and associations.
