The Chapman Memorial Symposium on Magnetospheric Motions will be held in Boulder, Colorado, June 18–22, 1973. The symposium is fourth in the series of the Triennial Boulder Geomagnetic Conferences. It is being arranged by the Environmental Research Laboratories of NOAA and the High Altitude Observatory of NCAR. Presently the only sponsor is AGU.
The symposium will concern the dynamic magnetosphere, the physics of its changing state, the detection and prediction of such changes, and the important influence of such motions on the environment.
