8048 Andrle           Discovered 1995 Feb. 22 by M. Tichy and Z. Moravec at Klet.
Named in memory of Pavel Andrle (1936-1991), Czech astronomer and celestial mechanician. Methods described in his textbook were used at Klet for the preliminary orbit determination of this minor planet. Name proposed by discoverers and endorsed by J. Ticha.
