✦ Synopsis

Orbital motions in 3He-A in very low magnetic fieM and driven by heat flow are studied using crossed detecting zero-sound fields. A precessional type of motion of the -~ field is frequently observed, though a rich variety of phenomena are also observed. There is no evidence for phase slip due to motion of nonsingular vortices along the surface. Motion of the t field following sudden parallel magnetic field turn-off is also observed above a threshold field change which is related to coherent dipolar energy. The time scale for these t-field changes is, however, a factor of about 10 2 larger than expected for the formation of composite solitons.
