我们在此讨论 1987 年 2 月 23 日在勃朗峰地下中微子观测站检测到的事件的特征，该事件由 7 秒内记录的 5 次相互作用组成。与第一次光学观测相比，测得的 5 个脉冲的能量、爆发的持续时间以及探测时间的提前证明，该事件可以通过探测大麦哲伦星云中恒星塌陷期间发射的中微子来解释。
We discuss here the characteristics of the event detected in the Mont Blanc Underground Neutrino Observatory on February 23, 1987, consisting of 5 interactions recorded during 7s. The measured energies of the 5 pulses, the duration of the burst, and the advance of the detection time in comparison with the first optical observations give evidence that the event can be explained in terms of detection of neutrinos emitted during the stellar collapse in the Large Magellanic Cloud.
