Scientific paper

According to Disney's (1973) observations, the galaxy IC 4329A is an 'extreme Seyfert galaxy' on account of the width of H-alpha (13,000 km/sec) and the high H-beta luminosity. The galaxy is an edge-on spiral close to the giant elliptical IC 4329, which is the brightest galaxy in a rich cluster of ellipticals and spirals in the Centaurus region. The present paper deals with a more detailed spectrophotometric study of the nucleus of IC 4329A with the Anglo-Australian telescope. The emission line intensities, their widths and structures, possible variability, and the shape of the continuum are discussed along with the absorption of the nucleus. It is shown that after correction for visual absorption, the nuclear luminosity is typical of lower-luminosity quasars.
