27719 Fast           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
Wilhelm Fast (1936-2005), a mathematician from Tomsk University, directed a project to measure the azimuths of the fallen trees due to the impact of the Tunguska body. From these data theoretical models of the impact were developed. The name also honors also his daughter Annie (b. 1978), who assisted in subsequent projects.
