Statistical analysis of solar proton events

Statistical analysis of solar proton events

A new catalogue of 253 solar proton events (SPEs) with energy &gt;10MeV and peak intensity &gt;10 protons/cm<sup>2</sup>.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...

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.https://www.ann-geophys.net/22/2255/2004/angeo-22-2255-2004.pdf
