The ACES‐II rockets were launched into the northern lights on 20 November 2022, from Andenes, Norway. They made multipoint measurements of small scale changes in the upper atmosphere's density and electric and magnetic fields on the edges of the northern lights. These features are consistent with a model of northern lights by which the changes in upper atmosphere play a role in creating these small‐scale features. We hope that these measurements will help to understand how the upper atmosphere helps to create these features.
