Quasi-Periodic Components of Solar Microwave Emission Preceeding The CME Onset on 19 October, 2001

The results of solar microwave observations in the Radio Astronomical Observatory NIRFI “Zimenki” are examined. Data analysis shows the presence of periodic component, that arose prior to burst connected to CMEs onset, and its absence after burst. Obtained data are compared with the dynamics of the development of activity on the solar disk. Results can be considered as the illustration of the dynamics of wave motions in the periods of flare activity.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
