抄録

Correlated enhancements of bremsstrahlung X-rays and VLF emissions were observed for about 10min at balloon altitude near Syowa Station (L=6.1), on December 14, 1985. The enhancements occurred quasi-periodically with the period of about 90s are investigated on spatial characteristics of energetic electron precipitation. A time sequence of localized X-ray images are composed. A systematic movement of the source region from geomagnetic SW to NE was found in the lowest energy channel of 22-35keV and its drift velocity was greater than 3.5km/s at X-ray generation height.
