摘要

Full 3D plasma observations in the cusp observed by thernCluster and Polar satellites in the northern and southernrnhemispheres are used to track the location of thernreconnection line at the magnetopause during southwardrninterplanetary magnetic field conditions. The lowvelocityrncutoffs in the flux measurements of thernprecipitating and the mirrored magnetosheathrnpopulation on open cusp field lines are used to estimaternthe distance of the observing satellite from thernreconnection line. The calculated distance isrnsubsequently traced back along model magnetic fieldrnlines to the magnetopause where the shear anglernbetween the geomagnetic field and the drapedrninterplanetary magnetic field is calculated.rnA series of cusp crossings during clock angles < 200°rnrevealed that magnetic reconnection favors anti-parallelrnreconnection within ±20° to 30° of the south direction.rnFor smaller clock angles the reconnection site switchesrnto a tilted X-line which crosses the componentrnreconnection site in the sub-solar region.
