The galaxy UCM 2303 + 1702, not previously known, was identified during the Universidad Complutense de Madrid (UCM) objective-prism survey. The optical spectrum displays emission lines with a blueward asymmetry. Forbidden lines cover a wide range of ionization exhibiting full width at half maximum (FWHM) unusually broad. An analysis of ionization range and the emission line ratios measured in the spectrum leads to a Seyfert 2 classification. The contour map of iosphotes of the CCD image shows an Sbc-Sc(+) spiral, nearly face-on, in disagreement with previous works reporting an anticorrelation between the (O III) line width and the Hubble morphological type in Seyfert parent galaxies. High quality IRAS coadded data have been used to study the far-infrared properties.
