Coronal Mass Ejections from the Same Active Region Cluster: Two Different Perspectives

Cremades Fernandez, Maria Hebe; Mandrini, Cristina Hemilse; Schmieder, B.; Crescitelli, A. M. (Springer, 2015-06)

The cluster formed by active regions (ARs) NOAA 11121 and 11123, approximately located on the solar central meridian on 11 November 2010, is of great scientific interest. This complex was the site of violent flux emergence ...

Analysis of Large Deflections of Prominence–CME Events during the Rising Phase of Solar Cycle 24

Sieyra, María Valeria; Cécere, Mariana Andrea; Cremades Fernandez, Maria Hebe; Iglesias, Francisco Andres; Sahade, Abril; Mierla, Marilena; Stenborg, Guillermo; Costa, Andrea; West, Matthew J.; D'Huys, Elke (Springer, 2020-09)

The analysis of the deflection of coronal mass ejection (CME) events plays an important role in the improvement of the forecasting of their geo-effectiveness. Motivated by the scarcity of comprehensive studies of CME events ...

Typical Profiles and Distributions of Plasma and Magnetic Field Parameters in Magnetic Clouds at 1 AU

Rodriguez, L.; Masías Meza, Jimmy Joel; Dasso, Sergio Ricardo; Démoulin, Pascal; Zhukov, A. N.; Gulisano, Adriana Maria; Mierla, M.; Kilpua, E.; West, M.; Lacatus, D.; Paraschiv, A.; Janvier, M. (Springer, 2016-07)

Magnetic clouds (MCs) are a subset of interplanetary coronal mass ejections (ICMEs). They are important because of their simple internal magnetic field configuration, which resembles a magnetic flux rope, and because they ...

Initiation of CMEs: the role of magnetic twist

van Driel Gesztelyi, Lidia; Manoharan, P. K.; Démoulin, Pascal; Aulanier, G.; Mandrini, Cristina Hemilse; Lopez Fuentes, Marcelo Claudio; Schmieder, B.; Orlando, S.; Thompson, B.; Plunkett, S. P. (Elsevier, 2000-11)

Recent multiwavelength observations, modelling results and theoretical developments indicate the importance of twisted magnetic configurations in solar active regions (ARs) in the initiation of coronal mass ejections (CMEs). ...

Low-Frequency Type-II Radio Detections and Coronagraph Data Employed to Describe and Forecast the Propagation of 71 CMEs/Shocks

Cremades Fernandez, Maria Hebe; Iglesias, Francisco Andres; St. Cyr, O. C.; Xie, H.; Kaiser, M. L.; Gopalswamy, N. (Springer, 2015)

Magnetohydrodynamic turbulent evolution of a magnetic cloud in the outer heliosphere

Telloni, Daniele; Zhao, Lingling; Zank, Gary P.; Liang, Haoming; Nakanotani, Masaru; Adhikari, Laxman; Carbone, Francesco; D'Amicis, Raffaella; Perrone, Denise; Bruno, Roberto; Dasso, Sergio Ricardo (The American Astronomical Society, 2020-12)

This Letter exploits joint observations of the same interplanetary coronal mass ejection by widely separated spacecraft to study, for the first time, the turbulent evolution of the magnetohydrodynamic (MHD) properties of ...

Three frontside full halo coronal mass ejections with a nontypical geomagnetic response

Rodriguez, L.; Zhukov, A. N.; Cid, C.; Cerrato, Y.; Saiz, E.; Cremades, H.; Dasso, Sergio Ricardo; Menvielle, M.; Aran, A.; Mandrini, Cristina Hemilse; Poedts, S.; Schmieder, B. (American Geophysical Union, 2009-06)

Forecasting potential geoeffectiveness of solar disturbances (in particular, of frontside full halo coronal mass ejections) is important for various practical purposes, e.g. for satellite operations, radio communications, ...

Measuring the magnetic field of a trans-equatorial loop system using coronal seismology

Long, David M.; Valori, G.; Pérez-Suárez, D.; Morton, R. J.; Vasquez, Alberto Marcos (EDP Sciences, 2017-07)

Context. EIT waves are freely-propagating global pulses in the low corona which are strongly associated with the initial evolution of coronal mass ejections (CMEs). They are thought to be large-Amplitude, fast-mode ...

The interplanetary magnetic structure that guides solar relativistic particles

Masson, S.; Démoulin, Pascal; Dasso, Sergio Ricardo; Klein, K. L. (EDP Sciences, 2012-01)

Context. Relating in-situ measurements of relativistic solar particles to their parent activity in the corona requires understanding the magnetic structures that guide them from their acceleration site to the Earth. ...

Characterization of CME-driven shock in the interplanetary medium using type II radio bursts

Diaz Castillo, Saida Milena (2017-11)

Type II radio bursts are indirect signatures of the fast magnetosonic shock formation in the heliosphere. Those types of MHD shocks accelerate electron beams that via plasma emission mechanism produce electromagnetic ...
