Observations of Small-Scale Magnetic Flux Ropes Associated With Significant Values of Partial Variance Increment Indices
Hu, Qiang; Chen, Yu
We report recent findings for the magnetic field configurations of small-scale magnetic flux ropes (SFRs) broadly defined and identified by using the Grad-Shafranov-based techniques for in situ measurements via the Parker Solar Probe (PSP), Solar Orbiter (SolO), and two Helios spacecraft. Since the current sheets were found to occur at boundaries …
Extent of the Magnetotail of Venus From the Solar Orbiter, Parker Solar Probe and BepiColombo Flybys
Sorriso-Valvo, Luca; Edberg, Niklas J. T.; Persson, Moa +20 more
We analyze data from multiple flybys by the Solar Orbiter, BepiColombo, and Parker Solar Probe (PSP) missions to study the interaction between Venus' plasma environment and the solar wind forming the induced magnetosphere. Through examination of magnetic field and plasma density signatures we characterize the spatial extent and dynamics of Venus' …
Solar Orbiter Data-Model Comparison in Venus' Induced Magnetotail
Jarvinen, Riku; Kallio, Esa; Edberg, Niklas J. T. +5 more
We investigate the structure of the Venusian magnetotail utilizing magnetic field and electron density measurements that cover a wide range of distances from the planet, from the first two Solar Orbiter Venus flybys. We examine the magnetic field components along the spacecraft trajectory up to 80 Venus radii down the tail. Even though the magneti…
Mirror Mode Storms Observed by Solar Orbiter
Fedorov, A.; Karlsson, T.; Owen, C. J. +8 more
Mirror modes (MMs) are ubiquitous in space plasma and grow from pressure anisotropy. Together with other instabilities, they play a fundamental role in constraining the free energy contained in the plasma. This study focuses on MMs observed in the solar wind by Solar Orbiter (SolO) for heliocentric distances between 0.5 and 1 AU. Typically, MMs ha…
Measurement of Magnetic Field Fluctuations in the Parker Solar Probe and Solar Orbiter Missions
Maksimovic, M.; Bale, S. D.; Krasnoselskikh, V. +17 more
The search coil magnetometer (SCM) measures the magnetic signature of solar wind fluctuations with three components in the 3 Hz-50 kHz range and one single component in the 1 kHz-1 MHz range. This instrument is important for providing in situ observations of transients caused by interplanetary shocks and reconnection, for the identification of ele…
Helios Observations of Quasiperiodic Density Structures in the Slow Solar Wind at 0.3, 0.4, and 0.6 AU
Arge, C. N.; MacNeice, P.; Di Matteo, S. +3 more
Following previous investigations of quasiperiodic plasma density structures in the solar wind at 1 AU, we show using the Helios1 and Helios2 data their first identification in situ in the inner heliosphere at 0.3, 0.4, and 0.6 AU. We present five events of quasiperiodic density structures with time scales ranging from a few minutes to a couple of…
