Strong spectral variability in NGC 7603 over 20 years.

KOLLATSCHNY W., BISCHOFF K. and DIETRICH M.

Abstract (from CDS):

We present results of a long-term optical variability campaign on the Seyfert1 galaxy NGC 7603 over a period of nearly 20 years. The optical continuum and the Balmer and Helium lines varied by a factor of 5 to 10 in this broad-line Seyfert1 galaxy. Furthermore, it is remarkable that the optical FeII line blends varied with the same amplitude as the Hα and HeI lines. During the first half of the campaign (until 1990) there was a strong correlation between Balmer decrement variations, Hβ intensity variations and emission line asymmetry. This behaviour changed afterwards when the Hβ line intensity was higher than on average.
