8339 Kosovichia           Discovered 1985 Sept. 15 by N. S. Chernykh at the Crimean Astrophysical Observatory.
Aleksandr Grigorievich Kosovichev (b. 1953), solar physicist and helioseismologist, has worked at the Crimean Astrophysical Observatory and at Stanford University. The naming also honors his wife, Tatiana Vladimirovna Kosovicheva, a doctor who worked in the Crimean Astrophysical Observatory's medical office.
