Arrival-time error of CME at the Earth. a Average of the absolute arrival-time error at the Earth forecasted by the real-time forecast result by GSFC/SWRC archived in the CCMC website (green), and SUSANOO using different CME initial speeds; with initial speeds derived from CACTus (blue), the LASCO catalog (red), and the best fit to IPS data (black). b Difference of the absolute arrival-time error between the SUSANOO simulation that best fit to IPS data and SUSANOO simulation using the initial speeds derived from CACTus (blue) and LASCO (red). The event numbers correspond to the numbers in the first column of Table 1. Dotted lines indicate a 1-h difference, which is equivalent to the error bar of the arrival time in this forecasting method
