Detector Notes

In choosing a detector channel for display, it is useful to know that selected detector channels respond to specific conditions in the space environment in especially sensitive ways. For example:

The >30 keV electron detectors generally show elevated fluxes at geographic latitudes between 55° and 75° during periods of high auroral activity.

The >300 keV electron detectors do not respond so strongly to auroral activity, but will observe unusually high fluxes in the outer Van Allen radiation belts (geographic latitudes 45° to 60° ) during periods of "relativistic electron events" as observed also by geostationary orbiting satellites.

The proton detector telescopes (especially the 30 - 80 keV and the 80 - 250 keV energy channels), will measure very elevated fluxes over a region extending from the outer Van Allen radiation belt to the auroral zone (geographic latitudes from 45° to 75° ) during global magnetic storms.

The >16 MeV and >35 MeV proton omnidirectional detectors will display very high responses over the Earth's polar regions (geographic latitudes higher than 65° ) during solar energetic particle events that often cause polar cap radio blackouts.
