摘要：

We present new spectroscopic observations of an old case of anomalous redshift - NGC 7603 and its companion. The redshifts of the two galaxies which are apparently connected by a luminous filament are z = 0.029 and z = 0.057 respectively. We show that in the luminous filament there are two compact emission line objects with z = 0.243 and z = 0.391. They lie exactly on the line traced by the filament connecting the galaxies. As far as we are aware, this is the most impressive case of a system of anomalous redshifts discovered so far.
