[1] The count rate recorded by a neutron monitor at South Pole, Antarctica, displays a long-term decline over the 32-year span from 1965 to 1997. The neutron rate follows an 11-year cycle with maxima at times of low solar activity, but the 1997 peak rate was approximately 8 % lower than the 1965 pea...
