Data of cosmic-ray intensity from the Calgary Super Neutron Monitor and interplanetary plasma and field data are divided into three groups corresponding to the magnetic clouds preceded by shocks, followed by interaction region and clouds without any such association, observed during the period 1967-

โฆ Synopsis
The cosmic ray 11-year variation for solar cycle 20 is attributed to the modulating effect of solar flare-induced shocks propagating through the interplanetary medium to the boundary of the heliosphere. The relative influence of these disturbances upon the cosmic ray intensity as a function of their travel time from the Sun is determined by a deconvolution of a linear system with the number of solar flares (importance > 1) and the observed cosmic ray intensity as the input and output respectively of this system. The 'impulse response function' so determined indicates that the solar flare -induced disturbances significantly modulate cosmic rays out to a distance of 70-90 AU where the modulating effect of the disturbances abruptly ends. This is interpreted as the boundary of the heliosphere.
