Description
Observations of an elongated, arc-shaped structure found in a new southern rich cluster of galaxies at z = 0.316 are reported. The structure is concave toward a major cluster member and is bluer than most galaxies in the cluster. The projected image of the structure is located near a close, possibly merging or interacting pair of galaxies at z = 0.328. Three possible explanations are briefly discussed: (1) accidental superposition of objects, (2) disrupted arm or tail of an interacting pair, and (3) gravitational lensing of a background object. 13 references
