Evolution of the Radial Size and Expansion of Coronal Mass Ejections Investigated by Combining Remote and In-Situ Observations
Bin Zhuang, Noé Lugaz, Nada Al-Haddad +4
A fundamental property of coronal mass ejections (CMEs) is their radial expansion, which determines the increase in the CME radial size and the decrease in the CME magnetic field s…
Investigating The Cross-section of Coronal Mass Ejections Through the Study of Non-Radial Flows with STEREO/PLASTIC
N. Al-Haddad, A. B. Galvin, N. Lugaz +2
The solar wind, when measured close to 1 au, is found to flow mostly radially outward. There are, however, periods when the flow makes angles up to 15 away from the radial…
Categorization of Coronal Mass Ejection Driven Sheath Regions: Characteristics of STEREO Events
T. M. Salman, N. Lugaz, R. M. Winslow +3
We present a comprehensive statistical analysis of 106 sheath regions driven by coronal mass ejections (CMEs) and measured near 1 AU. Using data from the STEREO probes, this extend…
Evolution of CME Properties in the Inner Heliosphere: Prediction for Solar Orbiter and Parker Solar Probe
Nada Al-Haddad, Noe Lugaz, Stefaan Poedts +2
The evolution of the magnetic field and plasma quantities inside a coronal mass ejection (CME) with distance are known from statistical studies using data from 1 au monitors, plane…
CME -- HSS interaction and characteristics tracked from Sun to Earth
Stephan G. Heinemann, Manuela Temmer, Charles J. Farrugia +9
In a thorough study, we investigate the origin of a remarkable plasma and magnetic field configuration observed in situ on June 22, 2011 near L1, which appears to be a magnetic eje…
Heliospheric Evolution of Magnetic Clouds
Bojan Vršnak, Tanja Amerstorfer, Mateja Dumbović +7
Interplanetary evolution of eleven magnetic clouds (MCs) recorded by at least two radially aligned spacecraft is studied. The in situ magnetic field measurements are fitted to a cy…
Comparison of magnetic properties in a magnetic cloud and its solar source on April 11-14 2013
P. Vemareddy, C. Möstl, T. Rollett +3
In the context of Sun-Earth connection of coronal mass ejections and magnetic flux ropes (MFRs), we studied the solar active region (AR) and the magnetic properties of magnetic clo…
Strong coronal channelling and interplanetary evolution of a solar storm up to Earth and Mars
Christian Möstl, Tanja Rollett, Rudy A. Frahm +15
The severe geomagnetic effects of solar storms or coronal mass ejections (CMEs) are to a large degree determined by their propagation direction with respect to Earth. There is a la…
A New Class of Complex Ejecta Resulting from the Interaction of two CMEs and its Expected Geoeffectiveness
N. Lugaz, C. J. Farrugia
A significant portion of transients measured by spacecraft at 1 AU does not show the well-defined properties of magnetic clouds (MCs). Here, we propose a new class of complex, non-…
Heliospheric Observations of STEREO-Directed Coronal Mass Ejections in 2008--2010: Lessons for Future Observations of Earth-Directed CMEs
N. Lugaz, P. Kintner, C. Moestl +3
We present a study of coronal mass ejections (CMEs) which impacted one of the STEREO spacecraft between January 2008 and early 2010. We focus our study on 20 CMEs which were observ…
Arrival time calculation for interplanetary coronal mass ejections with circular fronts and application to STEREO observations of the 2009 February 13 eruption
C. Möstl, T. Rollett, N. Lugaz +11
A goal of the NASA STEREO mission is to study the feasibility of forecasting the direction, arrival time and internal structure of solar coronal mass ejections (CMEs) from a vantag…
