在耀斑已基本确定为质子耀斑的情况下,为了对即将到达地球的太阳质子作出半定量的粗略预报(警报),即估计从观测到光学耀斑开始,需经多长时间质子通量将到达峰值;峰值强度有多大。为此,我们收集了1967年5月—1972年12月约五年半期间国外发表的比较系统的质子事件资料,以及相应的太阳耀斑和太阳射电资料。在确定质子 In the event that the flare has been substantially identified as a proton flare, in order to make a semi-quantitatively rough forecast (alert) of the solar protons that are about to reach the Earth, ie, how long the proton flux will have peaked from the time the optical flare was observed What is the peak intensity? To this end, we collected more systematic data on proton events published abroad during the period of May 1967 to December 1972 about five and a half years, as well as corresponding solar flares and solar radio data. After determining the protons
