چکیده

Collisionless shock nonstationarity arising from microscale physics influences shock structure and particle acceleration mechanisms. Nonstationarity has been difficult to quantify due to the small spatial and temporal scales. We use the closely spaced (subgyroscale), high-time-resolution measurements from one rapid crossing of Earth's quasiperpendicular bow shock by the Magnetospheric Multiscale (MMS) spacecraft to compare competing nonstationarity processes. Using MMS's high-cadence kinetic plasma measurements, we show that the shock exhibits nonstationarity in the form of ripples.

Anomalous foreshock field-aligned beams observed by Cluster

We report occasional observations of two simultaneously distinct ion foreshock components recorded by the Cluster spacecraft upstream of the Earth’s bow shock. In most occurrences, the lower-energy population originates as a field-aligned beam (FAB) associated with quasiperpendicular regions, which loses energy as the IMF rotates into oblique geometries. A second beam, with energies in excess o...

MMS Observation of Magnetic Reconnection in the Turbulent Magnetosheath

In this paper we use the full armament of the MMS (Magnetospheric Multiscale) spacecraft to study magnetic reconnection in the turbulent magnetosheath downstream of a quasi-parallel bow shock. Contrarily to the magnetopause and magnetotail cases, only a few observations of reconnection in the magnetosheath have been reported. The case study in this paper presents, for the first time, both fluid...

Dynamics of ion sound waves in the front of the terrestrial bow shock

Single spacecraft measurements from the Cluster 3 satellite are used to identify nonlinear processes in ionsound turbulence observed within the front of the quasiperpendicular terrestrial bow shock. Ion sound waves possess spatial scales that are too small for the efficient use of multipoint measurements on inter-satellite separation scales. However, it is shown how frequency domain modelling c...

Spatial distribution of upstream magnetospheric 350 keV ions

We present for the ®rst time a statistical study of 350 keV ion events of a magnetospheric origin upstream from Earth's bow shock. The statistical analysis of the 50±220 keV ion events observed by the IMP-8 spacecraft shows: (1) a dawn±dusk asymmetry in ion distributions, with most events and lower intensities upstream from the quasi-parallel pre-dawn side (4 LT± 6 LT) of the bow shock, (2) hig...

Dayside response of the magnetosphere to a small shock compression: Van Allen Probes, Magnetospheric MultiScale, and GOES‐13

Observations from Magnetospheric MultiScale (~8 Re) and Van Allen Probes (~5 and 4 Re) show that the initial dayside response to a small interplanetary shock is a double-peaked dawnward electric field, which is distinctly different from the usual bipolar (dawnward and then duskward) signature reported for large shocks. The associated E × B flow is radially inward. The shock compressed the magne...
