Abstract:
   We present the spectroscopic observations of 56 quasars that were discovered
   by AQD (Automated Quasar Detection) in a field of ∼25.3deg2, centred at
   (1950) RA l0h40m00s, Dec. 05deg00'00". These observations, with the CTIO 4-m
   telescope, led to the discovery by Clowes & Campusano of a large group of
   quasars with size ∼100-200h-1Mpc at z∼1.3. Quasars of particular
   interest are noted, including one that is a BAL quasar with z∼1.78.
