چکیده انگلیسی
Registration of high energy solar protons by middle and low latitude particle monitors during ground level enhancements (GLE) is investigated. We have developed a comprehensive method, for revealing weak GLE signals. The main result of the method is estimation of probability of error for given value of observed signal amplitude. We derived, that for middle energy protons, the 99% confidence limit of GLE signal detection is determined by â¼4.3Ï of observed signal, whereas for highest energy protons it is determined by â¼3.7Ï. Applying this method to GLE-65 at 28 October 2003, GLE-69 at 20 January 2005 and GLE-70 at 13 December 2006, we make conclusions about the maximal energy of protons during these events. We claim on the presence of >20â¦30 GeV protons in GLE-65 with the probability of error â¼7% and in the GLE-69 with the probability of error â¼0.4%. However, during GLE-70 maximal energy of protons was â¼10 GeV.
