A burst of eight neutrino events preceding the optical detection of the supernova in the Large Magellanic Cloud has been observed by the IMB detector. The events span an interval of 6 s and have visible energies in the range 20-40 MeV. Some comparisons between the signal and that expected from a supernova are made. We have found no other comparable burst during the operation of IMB.
