1733-565: A compact radio galaxy at low galactic latitude.

A low-resolution (7 A FWHM) spectrum of the galaxy was obtained on August 24, 1981. The object was beamswitched between two data windows of 2 x 5 arcsec that were separated by 15 arcsec. The seeing was 3 arcsec FWHM, with an integration time of 300 s. The white dwarf standard L930-80 (Oke, 1974) was used for flux density calibration, but owing to the poor seeing and small entrance apertures, the data are not photometric. A spectrum plot is presented, and wavelengths and intensity ratios for the emission lines are given in tabular form. It is pointed out that the deconvolved widths of the emission lines are all similar, with a mean of 530 + or 100 km/s in the emission frame. Taken with the forbidden O III 5007 A/H-beta ratio of 5.3, it is concluded that 1733-565 satisfies the conditions defined by Shuder and Osterbrock (1981) for a Seyfert 2 galaxy. However, unlike Seyfert 2s but in common with other radio galaxies (Grandi and Osterbrock, 1978), evidence is found of a broad component in the H-alpha profile but not in H-beta.
