Scientific paper

An on-line data base consisting of the auroral oval boundaries, structure, and particle fluxes from the DMSP F7 and F9 satellites from December 1983 through the present (with about a 7-month lag) is announced. The data are divided into distinct regions (e.g., diffuse aurora, discrete aurora, cusp proper, polar rain, etc.). The magnetospheric sources of the various particle precipitation regions are identified using a sophisticated pattern recognition technique (a neural network). For each region the boundaries are specified in both geographic and geomagnetic coordinates, and the average and peak values of the particle fluxes are given, along with the average energies.
