.一个脉动事件进行了研究，其中显示Ps6型的特性，周期约为20分钟。数据从一个大面积的磁强计和riometer测量已结合气球测量的电场，以获得详细的描述电离层电流系统的事件期间。本文所报道的脉动时间间隔大于3 hand，磁场变化很大，最大可达700 nT。结果表明，地面上测得的大部分磁干扰是由霍尔电流引起的。
. A pulsation event has been studied which showed Ps6-type characteristics with a period of about 20 min. Data from a number of magnetometer and riometer measurements over a large area have been combined with balloon measurements of the electric field to obtain a detailed description of the ionospheric current system during the event. The pulsations reported here occured over an interval longer than 3 hand showed large magnet ic variations, up to 700 nT A model of the three-dimensional current flow has been derived which agrees with the data. It is concluded that most of the magnetic disturbance measured on the ground is caused by Hall-currents.
