Optical identification of 100 IRAS Point Sources at high galactic latitude

The low-dispersion spectra of the First Byurakan Survey and the red and blue images of the Palomar Observatory Sky Survey have been used to identify optically 100 infrared sources from the IRAS Point Source Catalog. The work was carried out over the region 3^h 50^m ≤ α ≤ 7^h 40^m and +69° ≤ δ −73° with an area of 75 square degrees. The optical coordinates, their deviations from the infrared coordinates, V magnitudes, color indices, preliminary classes for all the objects, and a number of remarks on interesting objects are presented. Three objects were found to be quasars, 36 are galaxies (including Seyferts and an interacting pair), 5 are faint planetary nebulae, 9 are carbon stars, and 47 are stars of late M subclasses.
