Scientific paper

We present results of an H i survey of the cluster of galaxies Abell 262, using the Westerbork Synthesis Radio Telescope (WSRT). Eleven galaxies were detected in five fields. In a few cases the gas in these galaxies shows an asymmetrical distribution; the most likely explanation is the interaction between the cluster medium and the gaseous disks. Only two of the detected galaxies are slightly H i-deficient. At 40'' to the West of CGCG 160-049 we tentatively detect what may be an associated H i cloud. The total mass of this cloud is 2.5 x 10^8 M_{\odot}, and no optical counterpart has yet been found. Based on observations done at the Westerbork Synthesis Radio Telescope, in The Netherlands.
