Invited by Prof. Liu Zhong (PI of Fuxian Solar Observatory of Yunnan Observatories), Prof. Kiyoshi Ichimoto and his colleagues from HIDA Observatory of Kyoto University visited the Fuxian Solar Observatory from May 27, 2018 to June 8th.

Cooperation in following topics were carried out during this visit: (1) High resolution multi-wavelength imaging observation. An universal tunable filter system developed by HIDA observatory is installed at the imaging system of the New Vacuum Solar Telescope (NVST) in order to observe the high spatial resolution images at off-band -/+ 0.5 angstrom of the H\alpha line, simultaneously. (2) Discussion of the instrument polarization calibration and spectropolarimetric observation carried out at the NVST/FSO and DST/HIDA, respectively.
