A ROSAT Observation of the Jet and Nucleus of 3C 120

A section of the radio jet of 3C 120 has recently been detected in the optical with deep CCD images (Hjorth et al. 1995, ApJ 452, L17). We report on a ROSAT High Resolution Imager observation which was designed to ascertain if the radio-optical spectrum of the jet extends to the x-ray band, to determine if the nucleus is resolved with the 5" point response function, and to confirm the tentative detection of an x-ray feature adjacent to the location where the radio jet bends from PA = 270deg to a north westerly direction (Einstein data, unpublished).
