9403 Sanduleak           Discovered 1994 Oct. 31 by Spacewatch at Kitt Peak.
Nicholas Sanduleak (1933-1990) was a staff scientist at the Warner and Swasey Observatory from 1967 to his death. Renowned as a classifier and cataloguer of stars, he was the co-discoverer of SS 433 (V1343 Aql) and the cataloguer of the precursor object of SN 1987A.
