Origin of Helical Coronal Disturbances From the Sun
In order to predict geoeffective solar disturbances, is necessary to monitor
the solar activity, especially initiation of flares and CMEs (coronal mass
ejections). of many coronal activities involved with the large-scale in
the coronal volume, we report rotating prominences signify a launch of
CMEs without any flare activity. prominences are spinning at speeds of
several hundreds km/s moving on the solar surface with projected speeds
of > tens km/s, just like a tornado. simultaneous observations in microwaves
(Nobeyama radioheliograph; and white-light (SoHO/LASCO coronagraph), we
discuss relationship between the prominences and the CMEs regarding helical
structures and upward motions.
