Abstract: This paper analyses the solar proton events observed by the cosmic ray composition detector on board the Chinese "Fengyun 1" (FY-1) meteorological satellite.They include the events on Sept.4,1990 and on Feb.l and 2,1991 especially the later events are observed by the Rio-meter at the antarctic Zhong Shang station and by the superneutron monitor at Beijing Station.This shows that the events include the solar protons with very high energy and have very wide energy spectrum.Besides solar protons,a particles,carbon,nitrogen,oxygen and iron particles are also observed at the same time.It is the first time in China that the solar proton events roton event,Solar flare
