SN1987A, according to Wikipedia, is 168000 light-years away. At a difference of 0.0025%, the neutrinos should have arrived 4.2 years earlier. I wonder if they had any functioning neutrino observatories in December 1982 that they could use to verify?
Maybe not. One neutrino 'telescope' (DUMAND) was planned as early as 1976, but never came on line. It seems that scintillators picked up SN1987A, but I'm not sure how consistent detection would have been in 1982.
