Solar wind measurements from the Pioneer 10, Pioneer 11, and Voyager 2 spacecraft are now available through mid-1933. These measurements extend our knowledge of the outer heliosphere to heliographic latitudes that range between -10¿ and 75.5¿, and provide insight into the variation with solar cycle of the structure of the distinct solar wind. The average temperature, mass flux density, dynamic pressure, and kinetic and thermal energy flux densities varied strongly with solar cycle at the latitude of Pioneer 11 (10¿ to 17¿ N), but were almost constant in the vicinity of the solar equator. These parameters may have increased with latitude between the solar equation and 17¿ N. There was also a short-term variation in average solar wind parameters near the time of the 1986 solar minimum, when the inclination of the heliospheric current sheet dropped below the latitude of Pioneer 11. ¿ American Geophysical Union 1994
