Observations of emission line galaxies. II. The Seyfert galaxies MKN 1239, MKN 1298.
Abstract
Spectroscopic observations of the Seyfert galaxies Mkn 1239 and Mkn 1298 are presented. The spectrum of Mkn 1239 is noteworthy in terms of the absence of [N II] λλ6548, 6583 as well as the unusually low I(N1 + N2)/I(Hβ)NC ratio. This fact suggests that the narrow line spectrum of the object can be due to a component with features typical of normal H II regions, rather than to a Seyfert-2 component, as common in many Seyfert-1 galaxies. Mkn 1298 is a typical Seyfert-1 galaxy and seems to be a good candidate for future variability studies.
