Wavelength (angstroms) an Optical Survey of the Position Error Contours of Unidentfied High Energy Gammma-ray Sources at Galactic Latitude B> |20 @bullet |

We present results from our optical survey of the position error contours (“error boxes”) of unidentified EGRET sources at mid to high Galactic latitude. It is our intention to search for potential blazars that may have been missed in the original identification process of the three EGRET Catalogues and supplementary publications. We have first searched the error contours of unidentified sources at b > |20◦| for flat spectrum radio sources using the NASA Extragalactic Database (NED). For each such radio source found we conducted optical searches for counterparts using the Palomar 60-inch telescope, and University of Wyoming’s 2.3 and 0.6 m telescopes. Many of the radio sources have plausible optical counterparts, and spectroscopy will be conducted at a later date to determine which of these sources are quasars or active galaxies. Results show thats several sources are optically variable, and/or have flat or inverted radio to millimeter spectra and are thus potential blazars. Subject headings: gamma rays: observations
