文摘

We continue our study (Grechnev et al., 2013, doi: 10.1007/s11207-013-0316-6 ; PaperI) on the 18 November 2003 geoffective event. To understand possible impact on geospace of coronal transients observed on that day, we investigated their properties from solar near-surface manifestations in extreme ultraviolet, LASCO white-light images, and dynamic radio spectra. We reconcile near-surface activity with the expansion of coronal mass ejections (CMEs) and determine their orientation relative to the earthward direction. The kinematic measurements, dynamic radio spectra, and microwave and X-ray light curves all contribute to the overall picture of the complex event and confirm an additional eruption at 08:0708:20UT close to the solar disk center presumed in PaperI. Unusual characteristics of the ejection appear to match those expected for a source of the 20 November superstorm but make its detection in LASCO images hopeless. On the other hand, none of the CMEs observed by LASCO seem to be a promising candidate for a source of the superstorm being able to produce, at most, a glancing blow on the Earth magnetosphere. Our analysis confirms free propagation of shock waves revealed in the event and reconciles their kinematics with UV wavesand dynamic radio spectra up to decameters.
