Karl Herzfeld Auditorium of Hannan Hall - Rm 108

The recent discovery of the subauroral phenomenon called STEVE (Strong Thermal Emission Velocity Enhancement) has been an exciting development in auroral research. Discovered by citizen scientists, STEVE is an upper-atmosphere manifestation of an extremely thin yet long ribbon of vibrant purple and white hues across the night-sky. Scientific space and ground-based instruments combined with citizen scientists’ data provide a unique tool to analyze this new phenomenon. In this talk we will review some of the current understanding that the scientific community has reached in the last years regarding the phenomenon.
