Scientific paper

V and B light curves for supernova 1987A covering some 120 days from the outburst are presented and discussed; they are shown to be rather atypical for a type II supernova. The absolute magnitude at maximum brightness is also analyzed, and after applying a correction for interstellar absorption the authors obtain MV,max,0 = -16.1, and MB,max,0 = -14.7; it is then concluded that 1987A is a supernova quite fainter than average. A comparison with other known supernova is made and some similarity is found with peculiar objects such as 1948B in NGC 6946, and probably, 1909A in M101.
