Application to Geotail data Flank MP event on 1995-03-24 (Fujimoto et al., 1998, Fairfield et al., 2000) (X, Y, Z)~(-14, 20, 4) Re (GSM) Geotail E-T spectrogram Signature of “Rolled-up” vortices found in 1-SC data
Signatures of KHI at the flank MP Signatures seen ONLY WHEN a KH vortex is “Rolled-up”: □ Sheath plasma penetrating into the magnetosphere and sitting on the magnetospheric side of the low-density plasma. □ Low-density plasma flowing with an anti-sunward velocity higher than the magnetosheath plasma. Other signatures seen also when a KH vortex is not rolled-up: □ Quasi-periodic plasma/field perturbations with an period of a few minutes. □ Vortical plasma flow pattern. □ Magnetic field perturbation pattern under 3D KHI effect. Yellow: detectable only by multi-SC measurements White: detectable even with single-SC measurements
