The Ha full-disk images were successfully obtained by FMT 1 relocated from Hida Observatory of Kyoto University to Ica University in Peru under the international collaboration of the CHAIN 2 -project (see also Morita et al. (M18a) and UeNo et al. (A21a) in this JAS-Spring Meeting). Based on the FMT date we derived the 3-dimensional velocity field of the filament ejection. The features in extreme ultraviolet were also obtained by AIA 3 on board SDO 4 and EUVI 5 on board STEREO 6 -Ahead satellite.
