We report optical spectroscopic identification of two INTEGRAL sources,
detected in the INTEGRAL all-sky survey (Krivonos et al. 2006, in
preparation). Optical data were obtained with the Russian-Turkish 1.5-m
telescope (RTT-150, Bakirlitepe, TUBITAK National Observatory, Turkey),
using the TUG Faint Object Spectrograph and Camera (TFOSC).
IGR J01528-0326 --- The source is associated with the nearby edge-on spiral
galaxy MCG-01-05-047. The optical spectrum of the nucleus region of this
galaxy shows redshifted narrow H_alpha and [NII],6583 and other lines in
emission. From the intensity ratio lg([NII],6583/H_alpha) = -0.03, we
conclude that this source most probably is a Seyfert 2 AGN (Veilleux &
Osterbrock, 1987). This is also confirmed using the spectrum from 6dFGS DR2
(Jones et al., 2005), who measured the redshift z=0.01691 for this object.
IGR J02343+3229 --- The source is associated with the nearby edge-on spiral
galaxy NGC973. The optical spectrum of the nucleus region of this galaxy
shows redshifted narrow emission lines. We estimated the intensity ratio
lg([NII],6583/H_alpha) = 0.3, therefore, this source is most probably a
Seyfert 2 AGN (Veilleux & Osterbrock, 1987). We measured redshift z=0.01574
for this object.
