Remarkable electron fluctuations in the energy range less than 16keV were observed by a low-energy particle analyzer (ESP) on board the EXOS-C satellite (OHZORA) during an observation period for two weeks from November 26 to December 8,1984. The detected electron fluctuations are modulated at a frequency of about 1Hz, and appear only in the region from 0300 to 0900 MLT which corresponds to the result of the X-ray "Microburst". The electron fluctuation indicates a strong dependence on pitch angle.
