Abstract The SERF investigation of mass motions was outlined at a Cambridge meeting in 1979. Mid-course corrections of observing programs and a review of data took place in Palo Alto (1980) and Simferopol (1981). SERF participants at the recent Annecy SMY Workshop studied new mass motions data and noted the difficulty in co-locating Type II burst sources on or in front of loop transients. A model invoking a foreshock analogous to that at the earth's magnetosphere was suggested. Radio type IVs, co-spatial with dense hot plasmoids, may be the result of a plasma radiation emission mechanism. The injection of mass into the corona was observed in chromospheric and coronal lines recently with magnetic field changes and also at very high speeds into loops. The start time of coronal loop transients, if extrapolated to the chromosphere, usually precedes flare H-alpha or X-ray emission. Observational inferences from polarization and other studies begin to favor the three-dimensional bubble over the planar loop as a description of coronal mass motions.
