椭圆轨道卫星探索者12号利用各种粒子和磁场探测器对地球向阳面的外辐射区中心以及磁层和行星际空间之间的过渡区域进行了例行探测。从SUI探测器在整个112天的寿命期间收到的数据进行了全面分析。观察到的显著特征包括：证实在磁扰动期间外区软电子通量的增强和硬电子通量的减少;在增强期间外区硬电子最大值的向外运动;证实在磁暴初始阶段具有地磁场压缩的明确磁层的Chapman和Ferraro一般图象;证实了Frank和货车艾伦关于E ≥ 40 kev的电子恒定计数率的等值线倾向于从日下点向外突出近90°，并在夜晚一侧更接近地球的结果;并且普遍支持Gringauz，Kurt，Moroz和Shklovskii的结果，即在地球的夜晚一侧存在一个超过8 Re的区域，由极低能量的电子主导。
The elliptic orbit satellite Explorer 12 made possible the routine survey of the heart of the outer radiation zone as well as the region of transition between the magnetosphere and interplanetary space on the sunward side of the earth by means of a variety of particle and magnetic field detectors. The data received from the SUI detectors during the entire 112-day lifetime have been comprehensively analyzed. Salient features observed include: confirmation of the enhancement of soft electron fluxes and diminution of hard electron fluxes in the outer zone during magnetically disturbed times; the outward motion of the outer zone hard electron maximum during periods of enhancement; confirmation of the general Chapman and Ferraro picture of a well-defined magnetosphere with compression of the geomagnetic field during the initial phases of magnetic storms; the existence of a layer of quasi-thermalized plasma immediately outside the magnetosphere; confirmation of the result of Frank and Van Allen that the contours of constant counting rate for electrons with E ≥ 40 kev tend to protrude outward near 90° from the subsolar point and draw closer to the earth on the night side; and general support for the result of Gringauz, Kurt, Moroz, and Shklovskii that there exists a region beyond some 8Re on the night side of the earth dominated by very-low-energy electrons.
