Interplanetary protons (E/sub p/approx. =1 MeV) 1973--1986 and out to 22. 4 AU

Journal Article · · Geophys. Res. Lett.; (United States)
;
This paper uses annual mean counting rate data from detectors on two long-lived spacecraft, Pioneer 11 and IMP 8, to study the temporal and heliocentric radial distance variations of the intensity of interplanetary protons (E/sub p/approx. =1 MeV) over solar activity cycle 21. The Pioneer 11 data cover the time period April 1973 through 1986 and the heliocentric radial distance range 1.0
