Scientific paper

A clear bipolar (dawnward/duskward) signature in the Ey component was observed by the Cluster satellite in the magnetotail during a sudden impulse (si) on October 11,2001 (day 284). During the interval of the dawnward perturbation in Ey, the magnetic field strength in By and Bz started to increase. The Bx component was strongly enhanced during the duskward Ey perturbation. That is, the field change in By and Bz was earlier than that in Bx. We discuss possible mechanism for the E and B field variations observed at the time of the si event. We also observed quasi-periodic spacecraft potential (SP) variations following the si event in the magnetotail lobe and plasma mantle. The SP variations have good correlation with the magnetic field perturbations. We show that the perturbations at Cluster are caused by quasi-periodic solar wind lateral pressures squeezing the magnetotail axisymmetrically while moving tailward as suggested by previous studies.
