Abstract The Spatio‐Temporal Analysis of Field Fluctuations (STAFF) instruments onboard the Cluster satellites were designed to measure magnetic fluctuations in the 0.2–12 Hz and 0.2–180 Hz frequency ranges from the Search‐Coil Magnetometer (SCM), as well as electromagnetic spectra from the Spectrum Analyzer …

Magnetic reconnection at the magnetopause involves complex multiscale dynamics, in which most particles do not traverse the electron or ion diffusion regions directly but are instead energized along the separatrices and within the reconnection outflow. Multiple ion populations, i.e., hot and cold …

At the magnetopause, the boundary between the magnetosphere and the shocked solar-wind-dominated region, a fundamental process takes place: magnetic reconnection, which allows part of the solar wind plasma to enter the magnetosphere. In order to investigate this process at the scale of …

Abstract This study reports on a dayside magnetic reconnection event detected by the Magnetospheric Multiscale mission in the presence of a moderate guide field ( times the reconnecting magnetic field on the magnetosphere side) and assumed to be present in the whole …

The standard conditions considered for magnetic reconnection to occur are usually antiparallel magnetic field configurations with a shear angle of 180◦. Reconnection is often observed with an additional out-of-plane component of the magnetic field (guide field). We performed two sets of 2D …

This study reports on a dayside magnetic reconnection event with a moderate guide field (0.4 times the reconnecting magnetic field) detected by the Magnetospheric Multiscale (MMS) mission. The spacecraft traversed the compressed magnetospheric separatrix, observing cold ions with densities up to 10 …

Magnetic reconnection is a fundamental process that is ubiquitous in the universe. It converts magnetic field energy into heating and acceleration of plasma. On the dayside of the Earth’s magnetosphere, it is responsible for the dominant transport of plasma, momentum, and energy …

On 28th of August 2018 at 5:30 UT, MMS and Cluster were located in the magnetotail at about 16 earth radii (RE). They both suddenly crossed plasma interfaces. Located near the post midnight sector, Cluster transitioned from a cold plasma sheet to …

In July 2017, the MMS constellation was evolving in the magnetotail with an apogee of 25 Earth radii and an average inter-satellite distance of 10 km (i.e. at electron scales). On 23rd of July around 16:19 UT, MMS was located at the …
