Abstract

The Hamburg Quasar Survey is a wide-angle objective prism survey for finding bright QSOs in the northern extragalactic sky |b| > 20 deg; delta > 0 deg). The taking of the prism plates for 567 fields covering this area was completed in 1997. Including direct plates for fields with delta > 20 deg the plate archive contains now 1871 plates. In this paper we present a first list of 121 quasars, which were verified by slit spectroscopy in the years 1986-1991, while experiments to develop efficient selection techniques were made. The sample contains objects with brightnesses 15 <= B <= 19.5 and redshifts z <= 2.8 collected over various parts of the sky, for which objective prism plates were available at that time.
