AB: On 2 May 2003 from 00:00 - 02:30 UT, both the Cluster and Polar satellites encountered the magnetopause around 9:00 MLT. At this time, the Cluster satellites were in the mid-latitude northern hemisphere while Polar was in the southern hemisphere near the equator. Both the cold ion and the electric field data gathered by instruments on Polar revealed strong oscillations with a period of 4.5 minutes. The four Cluster spacecraft also observed the oscillating magnetopause as evidenced by their multiple encounters with the magnetopause. In the meantime, FTEs (flux transfer events) were observed almost simultaneously by electric and magnetic field probes on both Polar and Cluster. This event not only provides an excellent opportunity to study the motion, structure, fields and particle properties of the magnetopause at a large scale, but also helps us to better understand the global properties of FTEs. Data from multi-instruments of Polar and Cluster are utilized for the detailed analysis of this event and will be shown in this presentation.
