'Serpentine Emission' at the high latitude station Davis (17?23 September 1981)

Abstract

Almost a decade has passed since Gul'elmi and Dovbnya in 1974 introduced the high latitude class of magnetic pulsations known as 'Serpentine Emission'. These pulsations are observed in the polar cap, and have a period range of 0.5?10 s. Their name arises from their typical signature on a frequency vs time diagram, which has a sinuous 'serpent-like' appearance.
