Magnetic Properties of Metric Noise Storms Associated with Coronal Mass Ejections

Wang, Jing-Xiu; Wen, Ya-Yuan; Zhang, Yu-Zong

Using Nançay Radioheliograph (NRH) imaging observations, combined with SOHO/Michelson Doppler Imager (MDI) magnetogram observations and coronal magnetic field extrapolation, we studied the magnetic nature of metric noise storms that are associated with coronal mass ejections (CMEs). Four events are selected: the events of 2000 July 14, 2001 April …

Observational Features of Large-Scale Structures as Revealed by the Catastrophe Model of Solar Eruptions

Lin, Jun

Large-scale magnetic structures are the main carrier of major eruptions in the solar atmosphere. These structures are rooted in the photosphere and are driven by the unceasing motion of the photospheric material through a series of equilibrium configurations. The motion brings energy into the coronal magnetic field until the system ceases to be in…
