On the 54th day of 1987 an event occurred on Earth which gave reality to the fifty-five year old dreams of Baade, Zwicky, and Landauan event which confirmed thoughts of Chandrasekhar and Bethe. Also confirmed were the computer-based calculations of Colgate, Arnett, Burrows, Lattimer, Weaver, Woosley, Wilson and many others. The event was the arrival of a neutrino pulse that had been rushing towards the Earth for 170 000 yr. Had it arrived a few years earlier it would have gone unrecorded. Had its source in the Large Magellanic Cloud been much further away, it would have been too feeble to see. ~1016 neutrinos passed through the IMB detector (in the United States) in a few seconds. Only eight made recorded interactions. Simultaneously the Kamiokande detector (in Japan) recorded eleven. These numbers are in remarkable accord with the expectations of the above thinkers. It is a masterful triumph of the human intellect. Such pulses may pass our way every 10-100 years. *~ The chance that any more will be recorded may not be high since it requires the maintenance of large, complex detectors over these very long time periods. The detectors which recorded these events consisted of large masses of water viewed by many photomultiplier tubes located deep underground. **~ The events seen in the detectors are, individually, not very spectacular. In the IMB detector, for example, they have energies of only 20-40 MeV, close to that detector's threshold of visibility. An electron of 20 MeV will only light up approximately two dozen of the detector's 2048 phototubes. Such a signal must be picked out from a background due to radioactivity, electronic noise, and neutrino interactions from the atmospheric cosmic ray background. By appropriate filtering one can reduce the data to the cosmic ray neutrino rate, which is about two events per week in the 20-50 MeV energy band. A pulse of eight such events in six seconds is, therefore, truly extraordinary. This is what was recorded by IMB and similarly by a sequence of pulses in Kamiokande on February 23, many powers of ten above that expected from statistical fluctuations in the neutrino background.
