摘要: High velocity Hα ejections were observed in association with an important solar flare on March 12, 1969, and simultaneously Type II followed by IV radio emission detectable to 3–4 radii (R ⊙) from the center of Sun. From a sequence coronagraph photographs, trajectories determinations made for fragments spray which was visible distance 2 R ⊙. The temporal spatial relationship between optical events is discussed. mass motions appear be controlled gravitational field while move direction open magnetic lines.
