We report the discovery of SDSSJ115517.35+634622.0 , a previously unknown gravitationally lensed quasar .
The lens system exhibits two images of a z = 2.89 quasar , with an image separation of 1 { \farcs } 832 \pm 0.007 .
Near-IR imaging of the system reveals the presence of the lensing galaxy between the two quasar images .
Based on absorption features seen in the Sloan Digital Sky Survey ( SDSS ) spectrum , we determine a lens galaxy redshift of z = 0.1756 .
The lens is rather unusual in that one of the quasar images is only 0 { \farcs } 22 \pm 0 { \farcs } 07 ( \sim 0.1 R _ { eff } ) from the center of the lens galaxy and photometric modeling indicates that this image is significantly brighter than predicted by a SIS model .
This system was discovered in the course of an ongoing search for strongly lensed quasars in the dataset from the SDSS .
