Abstract
Eleven large directional discontinuities in the solar wind, simultaneously observed by Explorers 33, 35 and Heos 1 in the period Dec. 1968 to Jan. 1969, have been studied by the triangulation method. Testing the discontinuity normals deduced from the wind speed and timing parameters against those given by the magnetometer observations on different models suggests that 8 were tangential, 2 were rotational while 1 could not be identified. 3 small tangential discontinuities arriving within a period ≈ 35 min were also studied and as a result it is suggested that the solar wind remained stratified in separation planes over a distance ≈ 0.01 AU during that time. The implication of these results is briefly discussed.
