The proton component was extensively studied at high altitudes in a series of 6 Skyhook balloon flights at various latitudes (4, 41, 53, and 55' geomagnetic) using the Cherenkov scintillation counter teehnique. The proton differential energy spectrum was measured direetly in the region 250 to 750 Mev. It is observod that primary alphas and protons have the same form of rigidity spectrum from 1 to 17 Dev. A series of cutoff rigidities are measured in the vicinity of gamma = 53 and 55'. The intensity and composition of fast splash albedo is determined at gamma = 4, 53, and 55 deg . Significant time variations are observed between the three high latitude flights. Differences observed in the intensity and energy spectra of these three flights are discussed, and strong restraints are placed on possible modulating mechanism. (auth)
