Abstract
An analysis of galaxies in the field of the BL Lac object H 0414+009 i s presented. Direct images indicate that the BL Lac lies in a moderate ly rich (Abell richness class 0) cluster of galaxies, of which the gal axy hosting H 0414+009 is the dominant member. It is shown that a numb er of surrounding galaxies share the same redshift as the host galaxy of H 0414+009. Such an environment is consistent with those in which F R-I radio galaxies, the proposed parent population of BL Lac objects, are often found.
