Abstract Type : Poster Abstract Category : Sun and the Solar System Abstract : Coronal Mass Ejections (CMEs) are the most energetic eruptive events on the Sun in which hot coronal plasma is ejected out from the Sun into the interplanetary space. During the eruption process, these CMEs are usually accompanied by various phenomena like, flares, filaments, coronal jets etc. However, stealth CMEs are not associated with any of these low coronal features. This silent behaviour makes it more mysterious and distinguishable from other normal CMEs. The stealth CMEs can only be observed in upper corona with white light coronagraph. We use SECCHI/ STEREO and SOHO/ LASCO coronagraph observations to identify these events. Using the multi- viewpoint data from these instruments, we try to extract different properties of these stealth CMEs including their mass and velocity. We also attempt to compare these properties with that of the regular CMEs. Finally, the kinematic profiles of stealth CMEs will also be examined. This will help us in understanding the possible eruption mechanism that is responsible for these weak CMEs. |
