我们报告用望远镜阵列原型观测到来自马卡里安501的TeV伽玛射线耀斑。观测从1997年3月底至7月底连续进行。给出了伽玛射线强度的能谱和时间变化。在此期间，强度发生了一个数量级的变化，发现了可能的12.7 d的准周期振荡。
We report the observations of TeV gamma-ray flares from Markarian 501 using the Telescope Array Prototype. The observations were carried out continuously from the end of March to the end of July of 1997. The energy spectrum and the time variation of the gamma-ray intensities are shown. The intensity has been changed by an order of magnitude in this period, and the possible quasi-periodic oscillation of 12.7 days were discovered.
