Observation and explanation of a 0.3% sunward radial streaming of 1 to 5 GV cosmic radiationA high-energy proton telescope on board the HEOS-1 satellite obtained quiet-time anisotropy data between December 1968 and April 1970. Analysis of the data showed an integral radial streaming component towards the sun of 0.3% for particles of rigidity greater than 1 GV. This value is not explicable in terms of any experimental defect, the effect of the earth's magnetosphere or energy loss effects under spherical symmetry in the solar cavity. An explanation in terms of a falling off ecliptic gradient in cosmic ray density most affecting the 1-5 GV range would seem to be the most compelling.
