dc.descriptionWe present initial results of WIYN spectroscopic observations of selected objects detected in the Chandra Multiwavelength Plane (ChaMPlane) Survey in fields towards the Galactic anti-center. ChaMPlane is designed to identify low luminosity X-ray sources, both accretion-powered and stellar coronal, in the Galaxy. It also includes a wider-fields optical imaging Survey conducted with the NOAO Mosaic cameras to identify optical counterparts as well as H alpha-selected objects in the ~5 times larger field. We report spectra for 1048 objects in galactic anti-center (i.e. northern) fields, resulting in 609 type determinations. These include 5 new cataclysmic variables, 4 Be stars, 14 lithium-absorption stars, 180 stellar coronal sources (primarily dMe stars), and 29 new quasars. Bright optical counterparts of Chandra sources in this sample are most frequently dMe stars whereas a majority of the faintest (R ~21) spectroscopically classified Chandra source counterparts are quasars. The bulk of H alpha-selected sources appears to be roughly evenly divided between dMe stars and M stars at all magnitudes.
