The authors wish to thank an anonymous referee for his valuable comments and sugges­tions.Multiwavelength observations of the galaxy UCM 2257+2438 found in the Universidad Complutense of Madrid (UCM) objective-prism survey are reported. The optic spectroscopy, CCD imaging, near-infrared and IRAS photometric data suggest that this object is a narrow-line Seyfert 1 placed in the nucleus of a Sa nearly face-on galaxy with a significant contribution from starlight.engUCM 2257+2438, a new narrow-line seyfert 1 galaxyjournal articlehttp://dx.doi.org/10.1086/116293http://adsabs.harvard.edu/open access52To-disk ratiosRadio galaxiesSpectrophotometryPhotometryProfilesCatalogSpectraAstrofísicaAstronomía (Física)
