光学结构位于赤道的主要极光椭圆往往表现出不同的形态和动力学结构在高纬度地区。在某些情况下，出现的问题，这些光子发射现象的形成机制。空间和地面仪器的新发展使我们能够更清楚地了解在极光下结构形成中起作用的过程。此外，新的光学结构的发现有助于我们提高我们对发生在极光下区域的纬度和高度耦合的理解。然而，有几个问题仍然没有答案，需要开发新的仪器和分析技术。我们讨论在亚极光区的光学现象，总结观测结果，目前的结论，其起源，并提出了一些悬而未决的问题，值得进一步调查质子极光，分离的亚极光弧和斑点，稳定的极光红（SAR）弧，和史蒂夫（强热发射速度增强）。
Optical structures located equatorward of the main auroral oval often exhibit different morphologies and dynamics than structures at higher latitudes. In some cases, questions arise regarding the formation mechanisms of these photon-emitting phenomena. New developments in space and ground-based instruments have enabled us to acquire a clearer view of the processes playing a role in the formation of subauroral structures. In addition, the discovery of new optical structures helps us improve our understanding of the latitudinal and altitudinal coupling that takes place in the subauroral region. However, several questions remain unanswered, requiring the development of new instruments and analysis techniques. We discuss optical phenomena in the subauroral region, summarize observational results, present conclusions about their origin, and pose a number of open questions that warrant further investigation of proton aurora, detached subauroral arcs and spots, stable auroral red (SAR) arcs, and STEVE (Strong Thermal Emission Velocity Enhancement).
