Scope 
The inner magnetosphere is a highly dynamic and variable region, mainly due to the changes in energy input from the solar wind through the magnetotail and the plasma supply from the ionosphere. This complex system is affected by various cross-regional, cross-scale, and cross-energy coupling processes. To gain a deeper understanding of this dynamic system, it is essential to conduct comprehensive studies using coordinated observations with multi-point satellite measurements, ground-based networks, and theoretical modeling. Since the 24th solar cycle, such comprehensive studies have been made possible with the help of multiple satellites (Van Allen Probes, MMS, THEMIS, DSX, Arase, CubeSats, etc.), coordinated ground-based observations (THEMIS-GBO, SuperDARN, EISCAT, magnetometers, riometer, etc.), and numerical simulations (global kinetic model, MHD model, micro PIC, hybrid, particle tracing simulations, etc.). This session invites papers presenting recent results on the inner magnetosphere and its coupling/connection with surrounding regions, including the ionosphere and the outer magnetosphere. Papers on new projects (sounding rocket experiments, data assimilation/machine learning, CubeSats, etc.) and future spacecraft missions are also welcome.
