J. ; Malkan, M. A. ; Mandolesi, N. ; Partridge, B. ; Spinoglio, L. Abstract Multiwavelength observations--from radio to X-rays--of IRAS 1652+395, a far-infrared and X-ray source serendipitously discovered in the field of the BL Lac object Mrk 501, are reported. They show that IRAS 1652+395 is a new Seyfert 1 galaxy at a redshift of z = 0.069. The Balmer emission lines are only slightly broader (~ 1000 km s^-1^ FWHM) than the forbidden lines, suggesting a classification as a narrow-line Seyfert 1 galaxy, as reported by Osterbrock and Pogge in 1985. Its energy distribution from far-IR to X-ray frequencies is well fitted by starlight plus a power law of spectral index α = -1.2, with no evidence of a "blue bump." The object is the first active galaxy to be identified through both its far-infrared and X-ray emission.
