Research Abstract

We conduct two campaign observations of high-time resolution all-sky auroral imaging at multi-point stations in the Canadian arctic using 1/30-sec sampled cameras, in addition to the automated routine measurements of monochromatic all-sky cameras. We also combine these observations with the THEMIS satellite measurements. From these observations we obtain fine-scale structures and their development of auroras at the beginning of auroral substorms, as well as detailed characteristics of polar-cap plasma structures.
