The most two violent eruptions on the Sun are solar flares and coronal mass ejections, which we now believe originate from the solar magnetic field. The relationships among solar magnetic field, solar flares, and CMEs are therefore one of the most important topics in the solar physics domain (we prefer to write it as "1M2Bs", i.e., one magnetism plus two bursts of flares and CMEs). The "Advanced Space-based Solar Observatory" (ASO-S), dedicated to observing 1M2Bs simultaneously in a single platform, was proposed by the Chinese solar community in 2011. After a series of pre-studies, ASO-S was officially approved by the Chinese Academy of Sciences (CAS) at the end of 2017, and its launch is scheduled around the beginning of 2022. In order to achieve its scientific objectives, ASO-S aims to deploy three payloads: the Full-disc vector MagnetoGraph (FMG), Lyman-alpha Solar Telescope (LST), and Hard X-ray imager (HXI). The talk will introduce the mission's general frameworks, the latest progresses, and scientific expectations. Particular stress will be put on the significance of ASO-S being the first Chinese solar mission, which will be discussed from both the longitudinal and horizontal viewpoints.
Gan Weiqun is currently the chief scientist of the "Advanced Space-based Solar Observatory” (ASO-S) mission of the Chinese Academy of Sciences (CAS). After receiving his PhD from Nanjing University in 1989, he started working at the Purple Mountain Observatory of Chinese Academy of Sciences, and in 1995 he became a full professor. His research has touched different areas, including the spectral diagnostics, semi-empirical model atmosphere, hydrodynamic modeling, solar X-rays, gamma-rays, and space solar physics. He is the proposer of ASO-S, the first Chinese solar mission.
