Diagnostics of corotating interaction regions with the kinetic properties of iron ions as determined with STEREO/PLASTIC
STEREO/PLASTIC determines three-dimensional distributions of solar wind iron ions with unprecedented time resolution. Typically 300 to 1000 counts are registered within each 5 min time interval. For the present study we use the information contained in these distributions to characterize CIRs (C...

| description | STEREO/PLASTIC determines three-dimensional distributions of solar wind iron
ions with unprecedented time resolution. Typically 300 to 1000 counts are
registered within each 5 min time interval. For the present study we use
the information contained in these distributions to characterize CIRs
(Corotating Interaction Regions) in two test cases. We
perform a consistency test for both the derived physical parameters and for
the analytical model of CIRs of Lee (2000). At 1 AU we find that apart from
compositional changes the most indicative parameter for marking the time when
a CIR passes a spacecraft is the angular deflection of the flow vector of
particles. Changes in particle densities and the changes in magnitudes of
speeds are apparently less reliable indicators of stream interfaces. |
