Scientific paper

CCD measurements in the UBVRI bands are given for the bright isolated stars sited within 2 arcmin of SN 1987A, in order to facilitate photometry as the SN fades. Photometry of 38 stars brighter than V of about 20 that are within 30 arcsec of the SN is also provided, so that the contributions of these stars can be removed from aperture photometry. These measurements include those for the two stars that are within 3 arcsec of the SN. The reddening in the field of SN 1987A, from (U-B), (B-V) colors of 23 early-type stars, is E(B-V) = 0.17 + or - 0.02.
