Scientific paper

This paper reports on the earliest known photoelectric photometry for Supernova 1987A, obtained just twenty-four hours after the IMB/Kamiokande-II neutrino detection. Values of V = 4.78 (+/- 0.05), B-V = 0.00 (+/- 0.06) and U-B = -0.78 (+/- 0.06) were measured on Feb 24.336 UT 1987. This is twelve hours sooner than the next known reliable photoelectric observation.
