Abstract
Results of studies of bright radio sources in the constellation Cetus are p resented. More than 50% of the sources have radio spectral indices steeper than 0.9. Optical identifications have been determined for 35 sources. A la rge fraction of the radio sources are identified with weak blue galaxies. G iven their spectral indices, it is likely that these objects have redshifts z = 0.4-1.0. More than 20% of the steep-spectrum sources do not have optic al identifications and appear to be weak galaxies with z > 2. (C) 2000 MAIK "Nauka/Interperiodica".
