On the Access of Solar Protons to the Synchronous Altitude Region.
Abstract
Observations of 10-90 MeV solar protons were made near the synchronous altitude around the time of a sudden commencement at 0037 UT on 9 August 1972 using sensors aboard 1970-93A and 1972-10A. The observations indicated that the solar protons had direct access to the synchronous altitude region through the dawn flank of the magnetosphere and were transiently trapped with an e-folding lifetime of a few drift periods. A weaker dependence of the cutoff energy upon local time was observed than was predicted by the calculations of Gall et al. (1971a, 1971b). (Author)
