In 2001, 2002 and 2003, the Polar spacecraft probed the near equatorial plasma sheet at 9 RE near local midnight. Often the
magnetic field magnitude is very low in this region of space, below 5 nT. A variety of dynamic signatures are seen in the
magnetic field including mirror mode waves and sudden recoveries of the field, possibly inward moving compressions, possibly
associated with bursty bulk flows. We examine measurements closer to Earth at geosynchronous orbit and farther from Earth
(Cluster) to determine the origin of these dynamic compressions in preparation for the THEMIS mission that will probe the
region beyond Polar's apogee.
