Abstract
ABSTRACT Quasars are reported in an area 2.1 square degrees around the bright, disturbed galaxy NGC 520. For quasars brighter than m = 19.0 mag, areas to the southwest of NGC 520, in the direction of previously identified radio ejection, have a density of 2.9 per square degree or about 1.5 times the expected background density. Near NGC 520 the density increases until it reaches 15 times the expected background density for the four nearest quasars to the galaxy. Six of the seven nearest quasars to NGC 520 are aligned so accurately across the galaxy as to demonstrate physical association.
