Short summary
This study used the Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) and Finnish Meteorological Institute's all-sky camera. It looked at radio absorption and optical emission of the long east–west band of aurora (known as the growth phase arc), which forms at the start of substorms. The study found that radio absorption was consistently south of the bright auroral arc and that optical pulsating aurora occurs in the boundary region between the radio absorption zone and the bright arc.
