SUBMITTED TO THE ASTROPHYSICAL JOURNAL Preprint typeset using LATEX style emulateapj v. 7/15/03 IDENTIFICATIONS OF FIVE INTEGRAL SOURCES VIA OPTICAL SPECTROSCOPY

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering hundreds of new hard X-ray sources, many of which remain unidentified. We report on optical spectroscopy of five such sources for which X-ray observations at lower energies (∼0.5–10 keV) and higher angular resolutions than INTE-GRAL have allowed for unique optical counterparts to be located. We find that IGR J16426+6536 and IGR J22292+6647 are Type 1 Seyfert active galactic nuclei (with IGR J16426+6536 further classified as a Seyfert 1.5) which have redshifts of z = 0.323 and z = 0.113, respectively. IGR J18308–1232 is identified as a cata-clysmic variable (CV), and we confirm a previous identification of IGR J19267+1325 as a magnetic CV. By comparing the spectrum of IGR J18214–1318 to colors of various types of stars, we conclude that it is probably a high mass X-ray binary
