8246 Kotov           Discovered 1979 Aug. 20 by N. S. Chernykh at the Crimean Astrophysical Observatory.
Solar physicist Valerij Aleksandrovich Kotov (b. 1943) has worked at the Crimean Astrophysical Observatory for more than 30 years. In the early 1970s he pioneered the field of helioseismology, the study of the interior structure and energy sources of the sun and other stars.
