A sample of galaxies near the South Celestial Pole
This paper reports the results of a modest redshift survey carried out, at generally low Galactic latitudes, in the vicinity of the South Celestial Pole. Target galaxies were selected as a `representative' sample of underlying large-scale structures. Dimensions, approximate magnitudes and radial velocity measurements, are reported for 336 galaxies. Two obvious Seyfert 1 galaxies, one probably Seyfert 1 and three Seyfert 2 galaxies have been discovered. The redshifts are used to supplement existing data and serve to map southern voids and features out to 25000kms-1 in the region 270° < l < 330°, 0° > b > -45°. Three distinct superclusters and twenty apparent voids are tentatively identified. One Void, at l= 300°, b=-20°, cz= 16000kms-1, with a diameter of 6000kms-1, is as large as any yet mapped. It appears as part of a general underdense region.
