SuperDARN, Super Dual Auroral Radar Network is a unique international scientific project to study global ionospheric dynamics and space weather running mostly 40 high frequency radars whose fields-of-view cover wide longitudinal and latitudinal ionosphere in both hemispheres operated by more than 10 countries and institutions. NIPR Space and Upper Atmosphere Sciences research group has joined SuperDARN since its establishment in 1995 and has run Syowa SENSU SuperDARN radars at Antarctic Syowa station. SuperDARN provides a quasi real-time global ionospheric convection and electric potential map, which are essential to understand the status of magnetosphere, ionosphere and space weather condition, and have therefore been widely used and contributed to space weather research with a variety of collaborative efforts. The 65th Japanese Antarctic Research Expedition (JARE65) maintained and operated the SENSU Syowa radars for a year during their wintering period from Feb. 1st, 2024 to Jan. 31st, 2025. We here report the status, arosen issues and topics on the SENSU Syowa radars during JARE65 period and long-term future scientific and logistic perspectives.
