Scientific paper

Sime et al. (1984, 1985) have argued that two common characteristics of looplike coronal mass ejections are inconsistent with interpretation of such loops as shock waves moving through the corona. These are the cessation of lateral motions of the loop sides to form nearly radial, stationary bright columns or "legs" in the late stages of many mass ejections and the pushing aside or bending of pre-existing coronal features well outside the loop sides. Both are contrary to the notion of a propagating wave with a shock at its front and in disagreement with quantitative models of shock propagation in the corona. The authors report here Solar Maximum Mission (SMM) coronagraph observations of a looplike coronal mass ejection that occurred on July 6, 1980, and that was atypical in the two characteristics mentioned above. The sides of the loop moved laterally while they were visible and did not stop to form stationary "legs". A group of raylike features initially outside the mass ejection loop were not pushed aside or bent until the laterally moving loop sides passed over them. The authors thus propose the July 6, 1980, mass ejection as a candidate for identification as a shock wave. Quantitative analysis of the motion of the bright loop is also consistent with such an identification.
