| Outline of Final Research Achievements |
The plasma in the polar ionosphere often forms a mesoscale structure through various processes. In this study we made an all-sky imager having an ability to observe the mesoscale plasma structure and the relevant auroral structure at high time resolution, and analyzed data that were obtained from the imager. We identified the occurrence characteristics of the high-density region in the polar cap, and the nature of its structuring. We also found unprecedented spatial and temporal characteristics of the particle precipitation in the cusp.
