High resolution observations of the relaxed double radio galaxy B 0844+31 (4C 31.32) have revealed the existence of a radio-jet with a bright hot spot at its end and a relaxed, low brightness lobe beyond (van Breugel and Miley, t977). Here a multi frequency study is presented, including the spectral index distribution between 1.40Hz and 5 GHz and the polarization distribution at 1.4 GHz.
At 5GHz polarization was detected only near the prominent northern hot spot. The magnetic field distribution is shown to be circumferential. Some relevant source parameters are calculated and general aspects of the source are discussed. In particular we examine the energetics and confinement of the jet and the relation between the jet and the hot spot.
