Measurements of the velocities of galaxies thought to be associated with the giant radio galaxy NGC 6251 confirm the presence of a poor cluster with a systemic redshift of and a line-of-sight velocity dispersion of σz=283(+109,−52)kms−1. This suggests a cluster atmosphere temperature of T=0.7(+0.6,−0.2)keV, which is not enough to confine the radio jet by gas pressure. The core of NGC 6251 shows strong emission lines of [Oiii] and Hα+[Nii], but there is no evidence for line emission from the jet (detected in optical continuum by Keel).
