Ten years of photometric observations of SN 1987A are reviewed. The optical and near-infrared colors are now declining at less than 1 magnitude per 1000 days, which is consistent with both the infrared ``freeze-out'' and the possible energy sources powering the nebula. The ``uvoir'' bolometric luminosity at ten years is estimated to be log10(L) 36.1-36.4 ergs/s. The most recent photometric measurements are given in Table 1. A deep color-magnitude diagram shows that the young stars are concentrated within a projected distance of 25" (6pc) in a field out to 3' from the supernova. It is likely that Stars 2 and 3 which project to within 0.7pc of the supernova are associated with Sk -69 202.
