| Session Description | Solar activity has been high recently. Several extreme events, such as two successive X-class flares on 6 September of 2017, occurred. The Coronal Mass Ejections from the same active region resulted possibly the largest magnetic storm (in terms of Dst index) in the past decade. Measurements at geosynchronous orbit by GOES also show the solar energetic particle fluxes (>100 MeV) are among the highest in the past few years. The responses of the Earth’s magnetosphere to such extreme solar variations are complex and have been a long outstanding topic because of the intrinsic physical processes involved and also because of the practical space weather effects. Fortuitously there are currently multiple spacecraft with state-of-art instrumentation onboard dedicated to inner magnetosphere study, such as Van Allen Probes and Arase, in addition to other operation satellites such as GOES and POES and ground observations. These give us the best opportunity ever to tackle the problem of the general energy-transfer from solar wind to the inner magnetosphere, and the processes involved with the processes involved with wave generations and propagation, the loss, source, and acceleration of energetic particles. This special session provides a forum to discuss these important topics. We seek contributions of observational as well as data analysis and modeling papers to this session. |
