Description
The serendipitous discovery of a new type I Seyfert galaxy, IRAS
09149-6206, found during a search for planetary nebulae using the IRAS
Point Source Catalog is reported. The optical spectrum of this galaxy
shows very strong broad Balmer and Fe II emission, indicating the
existence of large optical depths, while the emission spectrum from the
narrow line region is relatively weak, with only the high excitation
lines present. The object presents extended forbidden O III emission,
and from the rotation curve, a mass of 8 x 10th the 9th solar masses is
calculated within a radius of 3 kpc. It is suggested that the activity
could have been triggered by interaction with a close faint companion.
