SMITH Department of Astronomy, University of Michigan, 500 Church Street, Ann Arbor, MI 48109 AND S. LIPARI Observatorio Astronomico de Cordoba, Laprida 854, 5000 Cordoba, Argentina Received 1997 December 15; revised 1998 March 27 ABSTRACT We report redshifts, magnitudes, and morphological classifications for 5369 galaxies with m_B_ <= 15.5 and for 57 galaxies fainter than this limit, in two regions covering a total of 1.70 sr in the southern celestial hemisphere. The galaxy catalog is drawn primarily from the list of nonstellar objects identified in the Hubble Space Telescope Guide Star Catalog (GSC). The galaxies have positions accurate to ~1" and magnitudes with an rms scatter of ~0.3 mag. We compute magnitudes (m_SSRS2_) from the relation between instrumental GSC magnitudes and the photometry by Lauberts & Valentijn. From a comparison with CCD photometry, we find that our system is homogeneous across the sky and corresponds to magnitudes measured at the isophotal level ~26 mag arcsec^-2^. The precision of the radial velocities is ~40 km s^-1^, and the redshift survey is more than 99% complete to the m_SSRS2_ = 15.5 mag limit. This sample is in the direction opposite that of the CfA2; in combination the two surveys provide an important database for studies of the properties of galaxies and their large-scale distribution in the nearby universe. Key words: galaxies: distances and redshifts-galaxies: photometry
