ULYSSES SOLAR-WIND PLASMA OBSERVATIONS AT HIGH SOUTHERLY LATITUDES

Solar wind plasma observations made by the Ulysses spacecraft through -80.2 degrees solar latitude and continuing equatorward to -40.1 degre es are summarized. Recurrent high-speed streams and corotating interac tion regions dominated at middle latitudes. The speed of the solar win d was typically 700 to 800 kilometers per second poleward of -35 degre es. Corotating reverse shocks persisted farther south than did forward shocks because of the tilt of the heliomagnetic streamer belt. Sporad ic coronal mass ejections were seen as far south as -60.5 degrees. Pro ton temperature was higher and the electron strahl was broader at high er latitudes. The high-latitude wind contained compressional, pressure -balanced, and Alfvenic structures.
