在日地能量方案(STEP)期间，利用自动光学仪器在沿极光带、低于极光带和高于极光带的几个纬度以及沿210°磁子午线的链站进行了极光观测。本文给出了仪器的详细情况和站点的位置。在初步分析中，利用阿拉斯加Kotzebue极光带站的极光资料以及210°和250°磁子午线上的高、低纬度站的磁场资料，论证了极光亚暴开始与多次Pi2磁脉动之间的关系。极光亚暴期间，PI2的每一次爆发与极光的每一次小尺度或大尺度的亮化和向极地的扩展具有良好的对应关系。
Auroral observations using automatic optical instruments have been conducted during the Solar Terrestrial Energy Program (STEP) period, at several latitudes along, lower, and higher than the auroral zone, together with the chain stations along 210° magnetic meridian. This paper gives details of the instrumentation and the locations of stations. In an initial analysis, auroral data from an auroral zone station at Kotzebue, Alaska, and magnetic field data from both high- and low-latitude stations along the 210° and 250° magnetic meridians were used to demonstrate the relations between auroral substorm onsets and multiple Pi 2 magnetic pulsations. The correspondence between each Pi 2 onset and each small- or large-scale brightening and poleward expansion of auroras during an auroral substorm with multiple onsets was good.
