Multiwavelength observations of IRAS 1652 + 395, an FIR 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/sec FWHM) than the forbidden lines, suggesting a classification as a narrow-line Seyfert 1 galaxy, as reported by Osterbrock and Pogge (1985). Its energy distribution from FIR to X-ray frequencies is well fitted by starlight plus a power law of spectral index alpha = - 1.2, with no evidence of a 'blue bump'. 26 refs.
