ResumoDetailed proton spectral and pitch angle distribution observations have been obtained from instrumentation flown aboard the NASA Small Scientific Satellite, S3-A (Explorer 45), launched from Kenya, Africa, into an elliptical orbit having an apogee of 5.24 RE, a perigee of 220 km, an inclination of 3.5°, and a period of 7.82 hours. Data used in this initial report are from two proton detectors and a three-axis fluxgate magnetometer. Data from the magnetometer are used to routinely display the particle data as a function of local pitch angle. The lower energy proton instrument consists of an electrostatic analyzer-channeltron configuration measuring proton energies from 0.8 to 30 kev in 16 energy intervals.
