| Scope | To date, we have three Japanese satellite missions to observe solar atmosphere, i.e., "Hinotori", "Yohkoh", and "Hinode", and revealed very dynamic nature of the solar atmosphere.These satellite observations allow us to see magnetic activities in the corona in X-ray, which cannot be obtained by ground-based telescopes. Also, thanks to seeing free condition, "Hinode" continuously observes the magnetic field in the photosphere. From these experiences, we have learned following three important requirements for the future missions to solve "coronal heating" and "solar flare" problems;1) seamless and simultaneous observation covering all temperature regimes from the photosphere to the corona, 2) high spatial and temporal resolution to resolve elemental structures and to track their evolution, 3) plasma diagnostic capability to quantify the dynamics of elementary processes. Recently, solar physics community in Japan proposed Solar-C_EUVST mission which is intended to be launched in middle of 2020s. Further, next-generation instruments, such as Parker Solar Probe (PSP), the Daniel K. Inouye Solar Telescope (DKIST), and SUNRISE will appear even before Solar-C_EUVST. Several proposals, e.g., PhoENiX, are also appearing. We will discuss in this session what we should study for further understanding of solar physics from current observations and numerical simulations and what we must prepare before 2020s. We welcome participations and presentations especially from Solar Terrestrial Physics (STP) community. | |
