Induced Precipitation of Inner Zone Electrons. Volume I. Observations.
Abstract
Narrow precipitation spikes of energetic electrons observed in the inner zone drift loss-cone during the 1968-1970 period by instrumentation on the OV1-14 and OV1-19 satellites are shown to have characteristics which are consistent with pitch-angle scattering produced through a resonant interaction with ground-based VLF transmissions. Analysis of the pitch-angle distributions indicates that for virtually all of the events, the electrons last interacted with the atmosphere in the vicinity of 55 deg to 62 deg East Longitude. The L-dependency of the spikes as a function of energy is consistent with scattering by a monochromatic wave. The presumption is that UMS, located at 44 deg E. and operating at a frequency of 16.2 kHz during this period, was responsible for these precipitation events.
