  H band observations with a spatial resolution of 0.15" carried out with the
Canada-France-Hawaii Telescope adaptive optics system show a galaxy between the
components of the double BAL quasar SBS 1520+530, thereby confirming this
system as a gravitational lens. The galaxy is located 0.40" from the fainter of
the two QSO images and is offset 0.12" from the line joining them. The H
magnitude of the lensing galaxy is ~1 mag fainter than expected from the
velocity dispersion derived for the lensing galaxy were it at z = 0.71 or z =
0.81, the redshifts of the two absorption line systems.
