The rapid crossing of the solar equatorial region by Ulysses as it returned from the south pole resulted in 7 crossings of the current sheet between 10"S and 20"N and 10 distinct solar wind interaction regions between 18"S and Both the extent of the current sheet and the latitude interval containing the interaction regions are a of= 2 less than were observed by Ulysses when it left the equatorial region in 1993. A map of the sheet in heliographic latitude and Barrington longitude reveals two folds corresponding to magnetic sectors. The coronal holes associated with the sectors, the interaction regions ancl high-speed streams have been identified, Two sectors were associated with a pair of asymmetrically-placed polar coronal holes whereas the other two sectors coincided with a pair of coronal holes on opposite sides of the equator. A. Introduction After leaving Jupiter in February 1992, Ulysses gradually traveled inward and southward making continuous observations of the solar wind a.
