Assuming a coronal plasma describable by the usual hydromagnetic approximation, with infinite electric conductivity, a two-dimensional model of prominence formation in a region containing a magnetic neutral sheet is constructed for a variety of initial conditions in which the magnetic field is at first vertical, varying axisymmetrically with respect to the neutral sheet to a maximum value at a distance of 70,000 km from the neutral sheet. While the plasma is initially in hydrostatic equilibrium in the first case, the pressure in subsequent cases is assumed to be of such a value that the plasma is in total lateral pressure equilibrium. Large lateral motions are produced in each case, apparently inhibiting the condensation of prominences and suggesting that a third component of the magnetic field and/or finite conductivity would represent the problem more realistically.
