Enhancing Triangulation of Interplanetary Type II Bursts through Wavevector Correction

Type II radio bursts, characterized by their slow frequency drift, are associated with accelerated electron beams at coronal mass ejection (CME)-driven shock fronts. These bursts serve as crucial indicators of shock propagation and space weather phenomena. Recently, Krupar et al. (2024) introduced a wavevector correction technique, initially applied to type III bursts, to account for the scattering effects in the solar wind, thereby enhancing triangulation accuracy. In this study, we investigate the application of this correction to type II bursts, aiming to improve localization and understand their relation to CME dynamics. We compare the corrected type II source locations with white-light observations of CMEs and in situ measurements of interplanetary shocks. Our findings indicate a significant improvement in the correlation between radio triangulation results and both white-light and in situ data, underscoring the potential of this correction method to refine our understanding of CME propagation and its impact on space weather forecasting.
