8471 Obrant           Discovered 1983 Sept. 5 by L. V. Zhuravleva at the Crimean Astrophysical Observatory.
The ballet-master, producer and teacher-humanist Arkadij Efimovich Obrant (1906-1974) organized and headed a children's dancing ensemble during the siege of Leningrad in 1942-1945. The first Obrant contest of choreographic art took place in St. Petersburg in March 2002.
