Abstract:
We combine the energetic electron observations from Polar and HEO (94-026, 95-034, and 97-068) to the large magnetic storm of May 2-9, 1998. These observations are taken by high-altitude high-inclination satellites at energies > 100 keV. The HEO (94-026, 95-034, and 97-068) satellites are in ~12 hour orbits at different local times while Polar is in an 18 hour orbit. The HEO coverage occurs roughly in the pre-noon/pre-midnight, post-noon/post-midnight and dawn/ dusk regions of the inner magnetosphere. Polar covers the pre-noon/pre-midnight region. HEO 94-026 and 95-034 provide coverage generally for L r 4 while HEO 97-068 covers Lr 2 and Polar covers Lr 3. These data are combined to provide a picture of the evolution of the energetic electrons with time, local time, L and energy. These combined observations will be presented and discussed in terms of the development of the storm from the electron perspective at mid to high latitude. We will also compare these off-equator observations to the observations taken near the equator by LANL geosynchronous and GPS satellites
