DESCRIPTION:Speakers: Prof. VASHENYUK\, Eduard (Polar Geophysical Institut
 e of RAS)\nComparative analysis of the characteristics of relativistic sol
 ar cosmic rays (SCR) \nin the two largest GLEs of 23 February 1956 and 20 
 January 2005 has been \nperformed. Using a modeling technique\, the parame
 ters of relativistic solar \nprotons (RSP) were obtained from ground-based
  observations by neutron \nmonitors (NM) and muon detectors. The two parti
 cle populations (components)\, \nprompt (PC) with high anisotropy and expo
 nential energy spectrum and \ndelayed one (DC) with moderate anisotropy an
 d power-law spectrum\, were \nshown to exist in both cases. The prompt com
 ponent was a cause of a giant \npulse-like increase at a limited number of
  NM stations\, and the DC caused a \ngradual increase with moderate amplit
 ude at the most NM stations over the \nglobe. It is argued that only expon
 ential energy spectrum (but not power-law \none)\, in combination with ene
 rgy dependence of the NM specific yield functions\, \ncould cause such gre
 at increase effect (~5000%) in both cases.\n\nhttps://indico.nucleares.una
