Solar particle penetration through the magnetosheath
Abstract
Data from HEOS-2 and from the NOAA experiment on Explorer 41 are presented which demonstrate that often the bow shock and magnetosheath seriously distort the flux of 1-MeV solar particles, so that it is no longer valid to assume that the magnetopause is the boundary between the interplanetary medium and the magnetotail. The change in absolute value and direction of the flux of particles that might be expected to occur at the magnetopause is not always seen exactly at that point. Rather, this change occurs sometimes further away in the magnetosheath, and sometimes the magnetopause looks completely transparent to arriving energetic particles as if the magnetotail were a continuation of the magnetosheath.
