Popis:	A neutrino burst was observed in the KAMIOKANDE-II detector on 23 February, 7:35:35 UT ( ±1 minute) during a time interval of 13 seconds. The signal consisted of 11 electron events of energy 7.5 to 36 MeV, of which the first 2 point back to the Large Magellanic Cloud (LMC) with angles 18° ± 18 ° and 15° ± 27°.A new analysis of the special low threshold trigger counts strongly indicates that KAMIOKANDE did not observe any signals at 2:52:36 which is the time claimed by the Mont Blanc group.
