Evolution of Coronal Mass Ejection Properties through Superposed Epoch Analysis from 0.2 to 2.2 au
Yakub Olufadi, Nada Al-Haddad, Florian Regnault +6
Coronal mass ejections (CMEs) are explosive and energetic events consisting of strong magnetic structures erupting from the solar corona. We use superposed epoch analysis to invest…
Influence of the Deformation of Coronal Mass Ejections on Their In-Situ Fitting with Circular-Cross-Section Flux Rope Models
Bin Zhuang, Noé Lugaz, Nada Al-Haddad +8
Understanding the properties, especially the magnetohydrodynamic (MHD) invariants, of coronal mass ejections (CMEs) measured in-situ is key to bridging the CME properties from the…
Can Alfvénic Fluctuations Affect the Correlation and Complexity of Magnetic Fields in Magnetic Ejecta? A Case Study Based on Multi-Spacecraft Measurements at 1~au
Camilla Scolini, Bin Zhuang, Noé Lugaz +4
We investigate whether Alfvénic fluctuations (AFs) can affect the structure of magnetic ejecta (MEs) within interplanetary coronal mass ejections (ICMEs). We study an ICME observed…
On the Role of Alfvenic Fluctuations as Mediators of Coherence within Interplanetary Coronal Mass Ejections: Investigation of Multi-Spacecraft Measurements at 1 au
Camilla Scolini, Noe Lugaz, Reka M. Winslow +3
Interplanetary coronal mass ejections (ICMEs) are defined as ''coherent'' if they are capable of responding to external perturbations in a collective manner. This implies that info…
The Width of Magnetic Ejecta Measured Near 1 au: Lessons from STEREO-A Measurements in 2021--2022
Noé Lugaz, Bin Zhuang, Camilla Scolini +7
Coronal mass ejections (CMEs) are large-scale eruptions with a typical radial size at 1 au of 0.21 au but their angular width in interplanetary space is still mostly unknown, espec…
Discrepancies in the Properties of a Coronal Mass Ejection on Scales of 0.03~au as Revealed by Simultaneous Measurements at Solar Orbiter and Wind: The 2021 November 3--5 Event
F. Regnault, N. Al-Haddad, N. Lugaz +4
Simultaneous in situ measurements of coronal mass ejections (CMEs), including both plasma and magnetic field, by two spacecraft in radial alignment have been extremely rare. Here,…
Multi-scale observation of magnetotail reconnection onset: 2. microscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +23
We analyze the local dynamics of magnetotail reconnection onset using Magnetospheric Multiscale (MMS) data. In conjunction with MMS, the macroscopic dynamics of this event were cap…
Multi-scale observation of magnetotail reconnection onset: 1. macroscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +22
We analyze a magnetotail reconnection onset event on 3 July 2017 that was observed under otherwise quiescent magnetospheric conditions by a fortuitous conjunction of six space and…
Investigating the Magnetic Structure of Interplanetary Coronal Mass Ejections using Simultaneous Multi-Spacecraft In situ Measurements
F. Regnault, N. Al-Haddad, N. Lugaz +5
In situ measurements from spacecraft typically provide a time series at a single location through coronal mass ejections (CMEs) and they have been one of the main methods to invest…
Applying Magnetic Curvature to to MMS data to identify thin current sheets relative to tail reconnection
A. J. Rogers, C. J. Farrugia, R. B. Torbert +1
Magnetic reconnection X-lines have been observed to be more common duskward of midnight. Thin current sheets have also been postulated to be a necessary precondition for reconnecti…
A New Method of 3D Magnetic Field Reconstruction
R. B. Torbert, I. Dors, M. R. Argall +6
A method is described to model the magnetic field in the vicinity of constellations of multiple satellites using field and plasma current measurements. This quadratic model has the…
Forecasting Periods of Strong Southward Magnetic Field Following Interplanetary Shocks
T. M. Salman, N. Lugaz, C. J. Farrugia +3
Long periods of strong southward magnetic fields are known to be the primary cause of intense geomagnetic storms. The majority of such events are caused by the passage over Earth o…
The Magnetic Field Geometry of Small Solar Wind Flux Ropes Inferred from their Twist Distribution
W. Yu, C. J. Farrugia, N. Lugaz +4
This work extends recent efforts on the force-free modeling of large flux rope-type structures (magnetic clouds, MCs) to much smaller spatial scales. We first select small flux rop…
Forward modeling of coronal mass ejection flux ropes in the inner heliosphere with 3DCORE
Christian Möstl, Tanja Amerstorfer, Erika Palmerio +7
Forecasting the geomagnetic effects of solar storms, known as coronal mass ejections (CMEs), is currently severely limited by our inability to predict the magnetic field configurat…
Factors Affecting the Geo-effectiveness of Shocks and Sheaths at 1 AU
N. Lugaz, C. J. Farrugia, R. M. Winslow +3
We identify all fast-mode forward shocks, whose sheath regions resulted in a moderate (56 cases) or intense (38 cases) geomagnetic storm during 18.5 years from January 1997 to June…
