Chromospheric lines (CaII, MgII, H-alpha) are observed with spectroscopes of IRIS and Hida/DST. The chromospheric temperature will be derived from CaII and MgII, and velocity field will be derived from H-alpha. On the other hand, photospheric magnetic fields under jets are observed with HINODE/SOT.
