Ps 6 disturbances: relation to substorms and the auroral oval
Ps 6 disturbances and associated omega bands are often considered to be part of the phenomenology of the recovery phase of substorms. We note cases of the initiation of Ps 6 activity at or very near the time of onset, either of a substorm expansive phase, a pseudobreakup, or a poleward border intensification. Thus, we claim that Ps 6 disturbances need not be viewed primarily as phenomena of the...
متن کاملProblems with mapping the auroral oval and magnetospheric substorms
Accurate mapping of the auroral oval into the equatorial plane is critical for the analysis of aurora and substorm dynamics. Comparison of ion pressure values measured at low altitudes by Defense Meteorological Satellite Program (DMSP) satellites during their crossings of the auroral oval, with plasma pressure values obtained at the equatorial plane from Time History of Events and Macroscale In...
متن کاملOn the nature of ULF wave power during nightside auroral activations and substorms: 2. Temporal evolution
[1] We present a statistical analysis of the time evolution of ground magnetic fluctuations in three (12–48 s, 24–96 s and 48–192 s) period bands during nightside auroral activations. We use an independently derived auroral activation list composed of both substorms and pseudo‐breakups to provide an estimate of the activation times of nightside aurora during periods with comprehensive ground ma...
متن کاملGround-Based Investigation of Near- Earth Space Plasma Processes in the NRL Space Physics Simulation Chamber
Introduction: The NRL Space Physics Simulation Chamber Laboratory conducts a broad-based research program addressing near-Earth space plasma physics. The unique Space Chamber device (shown in operation in Fig. 1) produces large-volume, steady-state, spacelike plasmas with conditions scaled to match various ionospheric and magnetospheric regions of interest. The program includes basic research i...
متن کاملAtmospheric Secondary Particles In Near Earth Space
In June 1998, the Alpha magnetic spectrometer AMS [1] had a test flight on board space shuttle and recorded some 108 events. The AMS proton and leptons spectrum [2, 3] have a magnetic latitude dependence. The spectral shape of primary cosmic rays can be explained by the geomagnetic rigidity cutoff. However, below the rigidity cutoff, a second spectrum was clearly seen. The energy of this second...
