Quasi-periodic electron ejections modulated by MHD oscilations of large-scale post-CME magnetic tubes (see, e.g., Zaitsev, Stepanov, 1975; Aschwanden, 1987, Aurass, Mann, 1987).
re-formation of the coronal magnetic structures
Extended EUV dimming area
on the disk and over the limb maps out the apparent location and configuration
of the white-light CME (see Thompson et al., 2000).
