Scientific paper

As part of a complete survey of IRAS galaxies close to the Galactic plane, the authors have discovered a bright QSO, at a redshift z = 0.0571 and a Galactic latitude of -9°.2. Its observed V magnitude is 13.55, and the Galactic reddening is estimated to be E(B-V) ≈ 0.23. Direct imaging and spectroscopy show that the object is surrounded by low surface-brightness fuzz, with strong lines of [O III]. The fuzz is some 2.4 mag fainter than the QSO in R. Unlike other QSOs recently discovered by IRAS, this object does not have a strong infrared excess, and has normal optical colors for a nearby QSO.
