Derivation of relativistic solar cosmic-ray spectra from the Baksan EAS array data
Fifteen increases in the intensity of solar cosmic rays (SCRs) from 30 investigated ground level enhancement (GLE) events have detected by Baksan EAS arrays in the period from 1981 until now. These data make it possible to refine the high-energy part of the SCR spectra calculated previously according to the data of the world-wide network of neutron monitors. A method for obtaining SCR spectra and calculating the specific yield functions for the Andyrchi, Carpet, and BMD Baksan arrays is briefly described. The SCR spectra for different instants in the GLE event of January 20, 2005 are presented.
