 note = {More than 500 photographs of comet Halley taken on the ground during this apparition are surveyed. Main disturbances of the ion tail are tabulated classifying these into streamer, ray, helix, knot, kink, and arcade, respectively. A focus is put on the December 31,1985,event, which includes an outstanding disconnection event (DE)-like knot. The event is compared with the heliospheric condition as obtained by the Sakigake/IMF observation in Part I of the present paper. The comparison derives a conclusion that the knot event is explained by the dynamic pressure model in Part III., 資料番号: SA0166185000},
