Coronal Mass Ejections can occur during solar flares unleashing a giant cloud of solar wind particles into space. Here you'll find an overview of the latest CMEs that where detected by the Cactus software of the SIDC. The Cactus software autonomously detects CMEs in image sequences from the LASCO instrument on board SOHO, the result is a list of detections by the software with the characteristics of the CME.
