27-day recurrence-associated phenomena of the solar wind (SOW), the plasma wave (PWP), and the interplanetary magnetic field (IMF) were detected by the Sakigake spacecraft. The heliospheric structures, having a neutral (current) sheet of ∿2×10^4km thickness and a "plasmasheet" of ≳7×10^5km thickness, during April, 1985-August, 1986 and September, 1986-July, 1987,were in the excursion and aligned phases, respectively. In the neutral sheet the IMF direction usually reverses in a minute. Using high time-resolution data, the average ion density and temperature in the heliospheric plasma sheet are also found to be ≳60/cc and ∿20×10^4K, respectively.
