8039 Grandprism           Discovered 1993 Sept. 15 by H. Debehogne and E. W. Elst at the European Southern Observatory.
The Grand Prism Objectiv-40cm astrograph (GPO), used without prism, has served for many years for searching for minor planets at La Silla. From 1978 to 1993, more than 1000 new minor planets were found with this instrument.
