摘要：
The relation between coronal mass ejections (CMEs) and solar flares are statistically Studied. More than 10,000 CME events observed by SOHO/LASCO during the period 1996-2005 have been analyzed. The soft X-ray flux measurements provided by the Geostationary Operational Environmental Satellite (GOES), recorded more than 20,000 flares in the same time period. The data is filtered under certain temporal and spatial conditions to select the CME-flare associated events. The results show that CME-flare associated events arc triggered with a lift-off time within the range 0.4-1.0 h. We list a set of 41 CME-flare associated events satisfying the temporal and spatial conditions. The listed events show a good correlation between the CME energy and the X-ray flux of the CME-flare associated events with correlation coefficient of 0.76. (C) 2009 COSPAR.
