Interplanetary Proton (0.61 < Ep < 3.41 MeV) Events Observed with Pioneer 11, 1973-1986 and out to 22.4 AU.

Abstract

A survey of interplanetary proton (0.61 < E sub p < 3.41 MeV) events is summarized in graphical and tabular form for the period April 1973 through December 1986. The observations were obtained by an effectively continuous data stream from the spacecraft Pioneer 11 as it moved outwards in the solar system from 1.0 to 22.4 AU. Two hundred and sixty five distinct events are identified. The spectra and intensities of the protons, presumed to be originally of solar origin, are influenced dramatically by propagative and accelerative processes in the interplanetary medium. Keywords: Solar protons; Heliosphere.
