摘要: [1] We infer the evolution of magnetopause reconnection from simultaneous in situ crossings and auroral observations by Cassini on 19 July 2008. Depending magnetosheath field, it proceeds (i) high-latitude lobe, producing a cusp spot aurora, to (ii) lower latitude but north Cassini, evidenced an enhancement pre-noon arc escape magnetospheric electrons during long boundary layer traversal, (iii) bursts south resulting bifurcations near-noon oval, electrons, short encounter. The conditions under which associated with this bursty were observed examined for three other examples. magnetosphere was strongly compressed high field strength every case. conclude that can proceed at different locations magnetopause, depending local magnetic shear plasma β conditions, occurs when is result significant solar wind-driven flux transport Saturn's outer magnetosphere.
