Scientific paper

The Mont Blanc observation of the Large Magellanic Cloud supernova, exploded on February 23, 1987 is summarized. The problem of two bursts, recorded in different underground detectors and separated in time by 4.7 hours, is also discussed. Since the different observations are not contradictory from the experimental point of view, some changes are required in the current predictions of the theoretical models of a gravitational stellar collapse in order to fit all the experimental data. Finally, the combined analysis of the data, recorded in all the neutrino and gravitational wave detectors running at the time of the supernova, clearly indicates a long duration of the phenomenon. Thus, any serious tentative to explain how a star ends its life as a supernova should be based on all the experimental data available, recorded in different, independent experiments running at intercontinental distances at the time of supernova 1987A.
