Abstract This paper describes the boundaries which have been observed by the magnetic field experiment aboard the VEGA-1 and VEGA-2 spacecraft during the Halley encounters on March 6 and 9, 1986. The outer boundaries are found to be closely related to the predicted cometary shock front. The inner boundaries near the closest approach are compared with plasma observations and with the results of MHD computer simulations in three dimensions.
