Abstract

During its southern transit Ulysses sampled the solar wind to −80.2° latitude. Slow streamer belt wind was seen only equatorward of −35°, but its influence extended to much higher latitudes. Reverse shocks bounding the equatorial CIR were seen as far south as −58.2°. High‐latitude compressional waves showed no clear correlation with that CIR. Speed and density patterns show that solar rotational modulation persisted up to 25° poleward of the slow wind. Compressional structures at highest latitudes were probably driven by spatial or temporal variations within the southern coronal hole.
