We present the spectroscopic observations of 56 quasars that were discovered by AQD (Automated Quasar Detection) in a field of |~ 25.3\, deg²|, centred at (1950) RA |10ʰ40ᵐ00ˢ|, Dec. |05∘00^00^|. These observations, with the CTIO 4-m telescope, led to the discovery by Clowes & Campusano of a large group of quasars with size |~100-200\, h⁻¹| Mpc at |z~1.3|. Quasars of particular interest are noted, including one that is a BAL quasar with |z ~1.78|.
