[PEM09-P02] AuroraX Project: Space weather research from Antarctica

*Ryuho Kataoka¹ (1.National Institute of Polar Research)

We would like to introduce a new 6-year project, called AuroraX. We will study space weather and space climate from Antarctica to understand how the Earth system is open to space. The polar cap is a special region where geomagnetic field is mostly open to the solar wind, and therefore the atmosphere is directly affected by the energetic particles from space. However, the auroras in the polar cap is less understood because of relatively poor coverage of observations. We will solve the technical problem by developing new cameras and by international collaborations. We will then contriute better understanding of the outer boundary of Earth system, via close collaboration with simulations and data science.

We will contribute to the international network observations of both aurora and cosmic rays. We develop a cutting-edge auroral imager inclding tough housing bearable for Antarctica. The system is low-power, portable, and the data will be obtained real-time, which will be tested in new Dome-Fuji station in 2023, and then distributed for future international collaboration in Antarctica. Main targets are high-altitude red aurora at 630.0 nm and low-altitude polar glow at 391.4 nm. The red aurora is used to identify open/closed boundary of geomagnetic field. The polar glow is used to measure the solar energetic particles (SEP). The high-energy SEP is also observed by neutron monitor and muon detector at Syowa Station. The cosmic ray observation at Syowa will be full-system and real-time data will be obtained every 10 min. Further, We will fully use the heritages. A suit of geophysical observations is ongoing in Syowa Station, including PANSY radar, radio, riometers, auroral imagers, and magnetometers. Also, unmanned measurements are ongoing.
