STEVE (Strong Thermal Emission Velocity Enhancement) phenomenon related structures have received much attention from space weather audiences in recent years. MacDonald et al. (2018, https://doi.org/10.1126/sciadv.aaq0030), reports on a link between these ionospheric structures and the subauroral ion drift for the first time. This commentary summarizes previously overlooked observations of a distinct type of detached subauroral arc by the aurora pioneer Carl Størmer in Norway between 1911 and 1940, including coordinated simultaneous multistation‐based altitude measurements. This commentary points out that his phenomenological descriptions and height measurements show a striking resemblance to modern descriptions and measurements of STEVE.

极光先驱CarlStørmer在高空分离的极光下弧上的早期地面工作现已被称为“ STEVE”

近年来，STEVE（强热发射速度增强）现象相关的结构引起了太空天气观众的广泛关注。MacDonald等。（2018，https://doi.org/10.1126/sciadv.aaq0030）首次报道了这些电离层结构与极光下离子漂移之间的联系。这篇评论总结了1911年至1940年间挪威极光先驱CarlStørmer对先前不同形式的分离的极光下弧的观测，包括基于多站点的同步同步高度测量。该评论指出，他的现象学描述和身高测量值与STEVE的现代描述和测量值极为相似。
