NGC 6251 is an E2 galaxy with mB = 13.6 mag (RC3) and heliocentric velocity 7400 km s−1(=106 Mpc for H0 = 70 km s−1Mpc−1). It is the host galaxy of one of the largest known radio sources in the sky: the radio lobes extend for 1°.2 (over 2 Mpc, Waggett et al. 1977, Readhead et al. 1978, Cohen and Readhead 1979, Jones et al. 1986, Jones and Wehrle 1994).
