Scientific paper

We investigate the origin of mass and influence of solar coronal mass ejections (CMEs) on the coronal streamer belt. The pre- and post-CME streamer belt structure from ~1.5 to 4 R&sun; are found by a tomographic reconstruction technique from STEREO B/COR1 data for the entire year 2008. These reconstructions allow us to make a case study for several CMEs during 2008. We find that the streamer belt frequently becomes notched at the time and location of a CME, indicating significant streamer mass loss. The notched structures are present for several days after some CME eruptions. A comparison of the mass lost by the streamer to the mass of a CME observed in the COR1 field of view can give a clue to the origin of the majority of the CME mass.
