The solar group in the Korea Astronomy & Space Science Institute (KASI) has made efforts in construction of facilities for solar physics. The first one is a 1.6 meter off-axis New Solar Telescope (NST) at the Big Bear Solar Observatory (BBSO). The KASI have participated in the construction of the NST in collaboration with the BBSO, and installed the Fast Imaging Solar Spectrograph (FISS) on a vertical table of Coude lab of the NST, which was developed with the solar group of Seoul National University (SNU). It is a unique system that can do imaging of H-alpha and Ca II 8542 bands simultaneously, which is quite suitable for study of dynamics of chromosphere. The next one is the Asian data center for the Solar Dynamics Observatory (SDO), which is a result of an agreement with the NASA for dissemination of the SDO data. The SDO data are being transmitted from the Stanford University to the KASI at a speed of 10 Gbps via the Global Ring Network for Advanced Application Development (GLORIAD), and then archived in the KASI’s storage, which is designed to store 650 terabytes of data per year. In this presentation, we will briefly introduce sciences using the NST and SDO data, which have been conducted by KASI scientists. Current status of NST observation and SDO data center will be reported to discuss a possible collaboration of solar physics in the East Asia Core Observatories Association (EACOA).
