| Research Abstract |
A new spectro-polarimeter was developed on the Domeless Solar Telescope at Hida observatory of Kyoto University aiming for realise new diagnosis of physical quantities such as magnetic field and electric fields of dynamic solar plasma. Chromospheric mass ejection phenomena (jets) occured on the solar limb were observed in spectral lines of Paschen series of neutral hydrogen and it was demonstrated that the magnetic field is aligned with the jets and neutral hydrogen is highly frozen to the magnetic field for the first time.
