Abstract

 The large and small Coronal Mass Ejections (CMEs) and mini-CMEs are observed by the Extreme Ultra Violet Imager (EUVI) on the Solar Terrestrial Relation Observatory (STEREO). These eruption events are usually associated with dimming and wave-like brightenings. Here, the images of the full SUN on 26 Apr 2008 with STEREO spacecraft (behind) with the cadences of 10 minutes and 150 seconds and pixel size of 1.59 arc second in pass band 195 and 171 Å were analyzed. The velocities of the large and small wave-like brightening were 221 km.s-1 and 6 km.s-1, respectively. The zernike moments of events and non-events were computed and these features were fed to the Support Vector Machine (SVM) classifier. Using this method, 697 mini-CMEs on three different regions of solar corona were detected. The number of mini-CMEs was increased when the CMEs occurred. The average velocity of mini-dimmings was 13.8 km.s-1.
