Scientific paper

The results of a search for IR radiation from a radio lobe of a radio galaxy are reported. The radio source 3C247 was examined in March 1982 with the UK IR telescope at Mauna Kea with a photometer fitted with a K filter and adjusted to a 7 arcsec FWHM aperture. The optical data, measured at 6500 A, yielded an R-K color of about 4, indicating the presence of a red star; the probability of the star being observed in that position by chance was calculated to have an upper limit of 0.0023. The low probability of coincidence suggests that the object is part of the radio lobe, so the IR emission may be an extension of the radio synchrotron emission derived from high-energy electrons.
