Abstract

Recently, Walsh, Carswell and Weymann¹ reported the discovery of two objects (0957+56A,B) with identical spectra and separated by 6 arc min. They suggested that a gravitational lens was responsible. The cumulative result of subsequent work on this object (see refs 2-9) corroborates this interpretation. The example of 0957+56A,B and the data presented here suggest a similar phenomenon is involved in the case of PG1115+08.
