Scientific paper

We have obtained moderate resolution optical spectra (resolving power=4000) in the range of 3500 to 4500 Angstroms towards a sample of stars in the direction of the star forming region W51 located in the plane of the Galaxy. These observations were made using the WIYN 3.5m telescope and Hydra instrument at Kitt Peak, Arizona. Here we present the results of our spectral classifications. These observations will be used to support GLIMPSE, a SIRTF legacy program, which will produce 4-band mid-infrared photometry for several million point sources in the Galactic Plane. In particular, we will use this sample to understand whether these mid-infrared colors can be used to determine the spectral type of ordinary stars.
