Abstract: | A third list of point sources from the IRAS Point Source Catalog (PSC), optically identified with late-type stars, is given.
The list contains data on 34 objects. The identification was based on the Digitized Sky Survey (DSS), the First Byurakan Survey
(FBS). blue and red maps of the Palomar Observatory Sky Survey, and infrared fluxes at wavelengths of 12, 25, 60, and 100
mm in the regions of +61° ≤ δ ≤ +65°, 06h45m ≤ α ≤ 17h28m and +69° ≤ δ ≤ +73°, 03h50m ≤ α ≤ 18h10m. Of 34 objects given in the IRAS PSC as unidentified sources of infrared radiation, 11 are associated with known stars in
existing catalogs, 6 are objects from the FBS survey of late-type stars, and 17 sources remained unknown in the optical range,
3 of them also being sources in the IRAS Serendipitous Survey Catalog (SSC). The optical coordinates, their departures from
the 1R coordinates, the V magnitudes, the color indices CI, and the preliminary spectral subtypes were determined. The objects
have optical magnitudes in the range of 7h.6-13m.6. Finder charts from the DSS are given for 23 objects.
