|Title:||Strong Fluctuations Of Energetic Electrons At Low Altitudes|
|Abstract:||Strong fluctuations (SF) of energetic electrons within the local loss cone (LC) from high resolution data on Active, a low altitude, high inclination satellite, are reviewed. The pitch angle diffusion rate of electrons at L > 4 is rapidly changing by one order up to the isotropic pitch angle distribution, corresponding to strong diffusion. The duration of the spikes to nearly strong diffusion limit is increasing with latitude. The statistical study shows the maximum occurrence of fluctuations within LC is in the noon sector and at latitudes 65-70°. Strong geomagnetic activity increases the probability of SF occurrence. One of the possible mechanisms consistent with the observations is the nonlinear precipitation oscillator (Davidson 1986; Davidson and Chiu, 1991). © 1997 COSPAR. Published by Elsevier Science Ltd.|
