Multi-wavelength observations of ground-based all-sky cameras are important for understanding the morphology and other characteristics of the aurora. National Institute of Polar Research (NIPR) is conducting the Phase X Research (Aurora X Project: FY2022~27). In the polar cap region, direct interaction between the solar wind and the atmosphere occurs, resulting in electron and ion precipitation over a wide energy range from several hundred eV (solar wind) to MeV (SEP).

We developed 10 all-sky cameras for this project: four at Syowa Station starting in 2023, two each at Casey and Davis Stations of Australia, and two each at Dumont d’Urville and Concordia Stations of France and Italy in 2025. In addition, the Arctic Scandinavian cameras in 2024.

We also started low-latitude aurora at Iitate observatory of PPARC since 2024.
