dc.descriptionWe present spectroscopic observations of galaxies lying within 1' from the QSO J2233-606 in the HDF-S. Several are found to be coincident in redshift with absorption line systems seen in the HST spectrum of the QSO. We detect a new quasar with z=1.3360 at only 45" angular separation from this QSO. This quasar pair is thus an ideal target for QSO environment studies: indeed, strong HI absorptions are seen at z(abs) = 1.3367 in the QSO spectrum, consistent with neutral hydrogen column densities log N(HI) > 16. A bright galaxy at 4"7 from the QSO is at z = 0.570, corresponding also to HI absorption in the QSO's spectrum. Other galaxies are also discussed.
