One of the greatest GLE The time profiles of the greatest GLEs.

Big and long anisotropy The visual anisotropy in CR variations at four NMs: CAPS-Cape Shmidt, MCMD-McMurdo, NAIN, THUL- Thule. GLE 69 as seen on subpolar NMs McMurdo and Thule. В первые 40 минут больша анизотропия очевидна, на самом деле возрастание в McMurdo заметно выше чем в Thule и через 10 часов

Conclusions The record enhancement in the counting rate at some southern polar NMs on 20 January 2005 ranges this event among the greatest GLEs. Nevertheless, high energy particles (>3 GeV) turned out to be of much less amount than in 1956 and 1989 events. The first particles came by very narrow beam and had a very hard spectrum. Already in some minutes after the onset the spectrum became soft and kept its form during the several hours with index Поток солнечных КЛ оставался анизотропным не менее 11 часов. Изменения характеристик анизотропии со временем, в основном, по-видимому, связаны с изменчивостью межпланетного магнитного поля. Полученные результаты можно и нужно улучшить.
