抽象的。我们目前的观察波和以上的等离子体频率（fpe）从三个高频电场实验最近发射到300-900公里的高度在活跃的极光火箭。主要观察到的HF波刚好高于fpe是窄带的，短寿命的发射，振幅范围从f ~ fpe保持。后一个时间尺度范围从0.6秒到6.0秒，对应于2-7公里的距离，假设该现象是静止的，并使用火箭速度将时间转换为距离。
Abstract. We present observations of waves at and just above the plasma frequency ( f pe ) from three high frequency electric field experiments on three recent rockets launched to altitudes of 300–900 km in active aurora. The predominant observed HF waves just above f pe are narrowband, short-lived emissions with amplitudes ranging from f ~ f pe holds. The latter timescale ranges from 0.6 to 6.0 s, corresponding to distances of 2–7 km, assuming the phenomenon to be stationary and using the rocket velocity to convert time to distance.
