与 FAST 卫星结合的光学观测表明，光学观测到的极光结构的宽度与从测量的电子能通量推断出的极光结构的宽度之间具有良好的一致性。这意味着这些结构是由 FAST 海拔约 4000 公里或以上的过程强加的。观察到了低至约 2 公里的各种宽度，但没有更精细尺度结构的例子。漫射极光极向边缘处的预破碎弱离散弧显示电子产生的光学结构位于向上行进的离子束的两侧。漫射极光赤道部分的光发射几乎完全是由沉淀离子引起的。光学观测是在 1997 年 1 月 31 日至 2 月 16 日期间，由一架携带全天空和三个窄视场电视摄像机的喷气式飞机在阿拉斯加北部进行的。
Optical observations conjugate to the FAST satellite show good agreement between the widths of auroral structures observed optically and those inferred from the measured electron energy flux. The implication is that these structures are imposed by processes at or above the ∼4000 km altitude of FAST. A variety of widths down to about 2 km were observed, but there were no examples of finer scale structures. A pre‐breakup weak discrete arc at the poleward edge of the diffuse aurora showed electron produced optical structures located on either side of upward going ion beams. The optical emission in the equator‐ward part of the diffuse aurora was caused almost exclusively by precipitating ions. The optical observations were made over northern Alaska between Jan 31 and Feb 16, 1997, from a jet aircraft carrying an all‐sky and three narrow‐field TV cameras.
