Understanding the Twist Distribution Inside Magnetic Flux Ropes by Anatomizing an Interplanetary Magnetic Cloud
Zhang, Tielong; Wang, Yuming; Shen, Chenglong +6 more
Magnetic flux rope (MFR) is the core structure of the greatest eruptions, that is, the coronal mass ejections (CMEs), on the Sun, and magnetic clouds are posteruption MFRs in interplanetary space. There is a strong debate about whether or not a MFR exists prior to a CME and how the MFR forms/grows through magnetic reconnection during the eruption.…
The Effects of Uncertainty in Initial CME Input Parameters on Deflection, Rotation, Bz, and Arrival Time Predictions
Gopalswamy, N.; Kay, C.
Understanding the effects of coronal mass ejections (CMEs) requires knowing if and when they will impact and their properties upon impact. Of particular importance is the strength of a CME's southward magnetic field component (Bz). Kay et al. (2013, https://doi:10.1088/0004-637X/775/1/5
Statistical Study of Magnetic Topology for Eruptive and Confined Solar Flares
Xu, Yan; Wang, Haimin; Liu, Siqing +1 more
Large flares and halo coronal mass ejections (CMEs) can often cause strong space environment disturbances and sequently a series of space environment effects. The X-class flares associated with halo CMEs are particular prone to these effects. In this paper, 58 X-class flares were collected and studied with the source locations in 30° from the disk…
Properties of the HPS-ICME-CIR Interaction Event of 9-10 September 2011
Morgan, Huw; Al-Shakarchi, Duraid A.
During 9-10 September 2011 the ACE, Wind, and SOHO spacecraft measured the complex interaction between an interplanetary coronal mass ejection (ICME) and a corotating interaction region (CIR) associated with the heliospheric sector boundary. Except for a few short periods, the suprathermal electrons are unidirectional, suggesting that the ICME mag…
