Magnetic Storms

A twin-fluxgate spinning sensor allows Earth's magnetic field to be described by three mutually perpendicular components. Field strength changes as small as 0.2 nanoTesla are measured.

Solar Flares

Ion chamber detectors provide whole-Sun X-ray fluxes for the 0.5-to-4 and 1-to-8 Angström wavelength bands. These observations provide a sensitive means of detecting the start of solar flares.

Solar Particle Events

Solid-state detectors with pulse-height discrimination measure protons, alpha particles, and electrons. Because the spacecraft travel in a geostationary orbit, the lower energy channels respond primarily to trapped outer-zone particles. The remaining channels measure solar particles and Galactic Cosmic Rays.

The electron detector measures the flux of electrons with kinetic energies > 2 MeV. The proton detector measures 7 energy bands from .6 to 500 MeV. The alpha-particle detector measures 7 energy channels from 3.8 to 500 MeV.
