BVRI PHOTOMETRY OF A FEW UNIDENTIFIED IRAS SOURCES

We selected 33 unidentified IRAS sources based on the following criter ia: i) galactic latitude more than 2 degrees, ii) have flux density hi gher than 1 Jy at 12 microns, iii) have good fluxes at 12, 25, and 60 microns with flux quality factor = 3, iv) and are in the declination z one between +60 degrees and -50 degrees. We identified the optical cou nterparts of these sources on the POSS, ESO, and SERC sky survey print s. Out of the 33 sources studied by us, 30 have optical counterparts w hich are stellar in appearance. We have also made BVRI CCD photometry of the optical counterparts of these sources. The IRAS colours and opt ical photometry suggests that IRAS 00408 + 5933, 02408 + 5458, 04101 3103, 04278 + 2253, 04296 + 3429, 04386 + 5722, 05089 + 0459, 05113 1347, 05245 + 0022, 06403 - 0138, 07430 + 1115, 08005 - 2356, 09032 - 3953, 09370 - 4826, and 14429 - 4539 are most likely late type post-A GE stars with cold detached circumstellar envelopes and the rest are m ost likely AGE stars with dust shells.
