The sector boundary (helispheric current sheet crossing) identified from in situ observations of interplanetary magnetic field and plasma properties referring the characteristics of the field and plasma in the heliospheric current sheet, i.e., spiral field polarity reversal and low velocity and high density. +/- refers to a polarity transition from outward/away polarity to inward/toward) polarity. y m d h 1982 6 23 6 +- 1982 7 4 12 -+ 1982 7 19 12 +- 1982 8 16 0 +- 1982 10 8 18 +- 1982 10 29 0 -+ 1982 11 5 12 +- 1982 12 3 12 +- 1982 12 15 16 -+ 1983 1 2 6 -+ 1983 1 29 12 -+ 1983 2 10 0 -+ 1983 3 18 18 +- 1983 4 3 18 -+ 1983 5 11 12 +- 1983 5 20 18 +- 1983 6 17 12 +- 1983 6 26 0 -+ 1983 7 11 6 -+ 1983 8 2 0 +- 1983 8 30 0 +- 1983 9 24 18 +- 1983 11 1 12 +- 1983 11 8 0 -+ 1983 11 15 0 +- 1983 11 24 6 -+ 1983 11 28 12 +- 1983 12 4 18 -+ 1983 12 9 0 +- 1983 12 10 6 -+ 1983 12 11 12 +- 1983 12 22 0 -+ 1983 12 26 18 +- 1984 1 1 0 -+ 1984 1 19 0 -+ 1984 1 28 0 -+ 1984 2 20 18 +- 1984 2 23 12 -+ 1984 5 6 0 -+ 1984 6 1 12 -+ 1984 6 15 6 +- 1984 6 28 18 -+ 1984 7 12 6 +- 1984 8 8 0 +- 1984 10 18 0 -+ 1984 12 21 18 +- 1985 1 18 0 +- 1985 4 13 18 +- 1985 4 14 18 -+ 1985 5 20 18 -+ 1985 5 31 0 +- 1985 6 17 0 -+ 1985 6 25 0 +- 1985 7 11 18 -+ 1985 7 23 0 +- 1985 8 18 0 +- 1985 9 14 12 +- 1985 10 11 12 +- 1986 5 30 18 +- 1986 6 27 12 +- 1986 7 20 18 -+ 1986 7 25 0 +- 1986 8 18 12 -+ 1986 8 20 0 +- 1986 9 10 6 +- 1986 10 3 0 +- 1986 11 1 18 +- 1987 1 4 18 +- 1987 3 31 18 +- 1987 5 9 0 -+ 1987 5 22 12 +- 1987 6 16 0 +- 1987 7 8 0 -+ 1987 7 12 12 +- 1987 8 1 0 +- 1987 8 29 18 -+ 1987 12 31 0 +- 1988 1 1 18 -+ 1988 1 25 18 -+ 1988 2 10 0 -+ 1988 6 18 18 -+ 1988 6 29 6 +- 1988 9 10 12 -+
