Polarimetric imaging of Comet Halley's coma and tail regions on January 5, 1986 has led to the discovery of a small region in the inner coma with low polarization, as well as two enhanced-polarization regions in the outer coma which are probably associated with jet activities. The coma's low-polarization region may also be associated with a fresh dust-jet's ejecta; in this case, the low polarization would be due to multiple scattering in a region of high dust concentration. The polarization vectors are generally noted to lie perpendicular to the scattering plane. 17 refs.
