1989A&A...219...98M A compact group in Virgo G.A. Mamon Department of Physics, New York University, 4 Washington Place, New York, NY 10003, USA DAEC, Observatoire de Meudon, F-92195 Meudon Principal Cede,, France, Received January 9, accepted February 14, 1989 Summary. An automated search for subgroups in the Virgo cluster that strictly satisfy Hickson's (1982) compact group selection criteria is performed. The data is taken from Tully's (1987) recent survey. The algorithm returns a single compact group, whose brightest member is M 60 (NGC 4649). No interloping galaxies are found to spoil the isolation of the group. The group would be the closest known compact group. Its nature (dense system or chance alignment of galaxies) is discussed. The presence of a compact group in Virgo suggests that other clusters may also be the sites of such systems. Key words: clusters of galaxies - numerical methods
