Scientific paper

Spectroscopic observations of 266 galaxies in the Hya-Cen region are reported. Redshift data obtained at 350-700 nm with dispersion 21 nm/mm using the UNIT spectrograph and RPCS detector on the 1.9-m Radcliffe Reflector telescope at SAO during March 1985, May 1986, and March 1987 are presented in tables and graphs and briefly characterized. It is shown that the Hya supercluster is separated from the Cen supercluster by a large void at right ascension 11 h 40 min, declination -35 deg, and radial velocity 5200 km/sec; a bridge of galaxies at velocity about 3200 km/sec connects the two superclusters.
