A prolonged period of By>0 dominated IMF conditions was monitored by WIND on Dec., 18--19, 1994. Observations on convection over the southern polar cap in the middle of this period (IMF Bz~0) were available from AKEBONO. Detection of the well-known dawn-to-dusk flow observing simultaneously energy-dispersed ions in the cusp strongly indicates that the field lines reconnected at the dayside were azimuthally accelerated. GEOTAIL happened to be in the duskside flank at (XGSM,ZGSM)~(-15~-23,-1~-7)RE. The GEOTAIL data not only prove that this near-tail flank region in the southern hemisphere is filled with azimuthally accelerated flux tubes that are loaded with solar wind plasma, but they also show that O+ ions are transported tailward along these field lines. The latter is a new finding which suggests a route for transporting O+ ions from the ionosphere to the magnetotail.¿ 1997 American Geophysical Union
