| Zusammenfassung |
| A new catalogue of 253 solar proton events (SPEs) with energy >10MeV and
peak intensity >10 protons/cm2.s.sr (pfu) at the Earth's
orbit for three complete 11-year solar cycles (1970-2002) is given. A
statistical analysis of this data set of SPEs and their associated flares
that occurred during this time period is presented. It is outlined that 231
of these proton events are flare related and only 22 of them are not
associated with Ha flares. It is also noteworthy that 42 of these events are
registered as Ground Level Enhancements (GLEs) in neutron monitors. The
longitudinal distribution of the associated flares shows that a great number
of these events are connected with west flares. This analysis enables one to
understand the long-term dependence of the SPEs and the related flare
characteristics on the solar cycle which are useful for space weather prediction. |
