NED Abstract

1998IAUC.7024B...1J Circular No. 7024 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION NGC 7582 B. Joguet, European Southern Observatory (ESO); D. Kunth, Institut d'Astrophysique de Paris; and R. Terlevich, Institute of Astronomy, Cambridge, report the discovery of a bright flare in the Seyfert 2 galaxy, NGC 7582, as revealed by spectroscopy (integration time 2700 s; spectral resolution 0.3 nm; range 370-670 nm) performed on July 11 with the ESO 1.54-m telescope at La Silla: "The galaxy is located at R.A. = 23h18m23s.50, Decl. = -42o22'14".0 (equinox 2000.0). From the spectrum, broad line components at H-alpha and H-beta are seen with a blueshift of about 2500 km/s with respect to the narrow lines. The FWZI of the broad H-alpha component is about 25 000 km/s. Also, broad Fe II emission lines can be observed around 440 and 540 nm. Another spectrum (integration time 3600 s; spectral resolution 0.2 nm; range 340-540 nm) taken on June 1 with the ESO 1.52-m telescope does not show any sign of broad lines in the nucleus of this galaxy. The continuum brightened by about a factor of two at 540 nm between the June and July spectra. The nuclear magnitude computed with the July spectrum at 540 nm is 14.3." 1998 October 6 (7024) Daniel W. E. Green
