• Time series of parameters associated with a CIR– Between the two shock waves, andcentered on the interface, the plasma iscompressed– This implies a higher density of S’ plasmathan unshocked S plasma– Similarly the shocked F’ plasma is higherdensity than unshocked F plasma, but thedensity of F’ < density S’ since fast plasmahas lower density than slow plasma– The S’ plasma is moving faster than S, butslower than F’ which is slower still than F– The S’ plasma has a positive azimuthalvelocity, the interface a zero azimuthalvelocity, and the F’ a negative azimuthalvelocity– The magnitude of the magnetic field iscompressed between the shocks– There is increased magnetic turbulenceand temperature in the interaction region– Not shown is a tipping of the IMF out of theecliptic plane
