[36.04] Do locations of CME source regions relative to the HSB determine the appearance of the CME?

The relationship between CMEs and the coronal helmet streamer belt has been the subject of several studies. Recent studies using SOHO/LASCO observation presented a rather complicated picture of this relationship (Subramanian et al., 1999). It has been suggested that a CME may blowout, create, disturb, have no effect on or be clearly displaced from a streamer. We investigate the possibility that these different interactions may be due to the locations of the CME source regions relative to the helmet streamer belt. Estimated Helmet streamer belt configurations obtained using Potential Field Source Surface Models based on SOHO/MDI synoptic maps are compared with combined LASCO-EIT movies on the LASCO website for this study.
