A new two image gravitational lens system has been discovered as a result of the Cosmic Lens All-Sky Survey ( CLASS ) .
Radio observations with the VLA , MERLIN and the VLBA at increasingly higher resolutions all show two components with a flux density ratio of \sim 7:1 and a separation of 1 \aas@@fstack { \prime \prime } 34 .
Both components are compact and have the same spectral index .
Follow-up observations made with the VLA at 8.4 GHz show evidence of a feature to the south-east of the brighter component and a corresponding extension of the weaker component to the north-west .
Optical observations with the WHT show \sim 1 \aas@@fstack { \prime \prime } 7 extended emission aligned in approximately the same direction as the separation between the radio components with an R-band magnitude of 21.8 ~ { } \pm~ { } 0.4 .
