Abstract

A burst of eight neutrino events preceding the optical detection of the supernova in the Large Magellanic cloud has been observed in a large underground water Cherenkov detector. The events span an interval of six seconds and have visible energies in the range 20–40 MeV.Received 13 March 1987DOI:https://doi.org/10.1103/PhysRevLett.58.1494©1987 American Physical Society
