On 25 November 2001 a low frequency type of ULF wave, called Pc5, was continuously recorded for many hours by the CARISMA magnetometer chain in Northern Canada. During a 3-hour subset of this interval, these Pc5 waves were picked up by more than a dozen scientific satellites, all collocated in the dusk sector at different altitudes:

> 110 000 km the four ESA Cluster satellites outbound from the magnetosphere across its boundary, the magnetopause
[red orbit]
~ 58 000 km the NASA Polar spacecraft traversing the magnetosphere
[blue orbit]
~ 35 785 km four NOAA geostationary satellites: GOES-8, -9, -10 and -12
[green orbit]
