Itzigsohn at La Plata. Named in memory of F. A. Munoz, an assistant in the department of extra-meridian astronomy at the La Plata Observatory and involved for many years in computational and observational work on minor planets at La Plata; he also took an active part in site testing for the 2.15-m Argentine telescope.
