Synoptic maps of all the events for Carrington rotation numbers 2243, 2248, 2249, and 2250 as provided by the http://connect-tool.irap.omp.eu (Rouillard et al. 2020) at the start time of the eruption on the solar disk, as extrapolated from the height-time fit. The yellow stars indicate the Carrington coordinates of the eruptions as estimated by triangulation method in the high corona and listed in Table 1. Cyan stars mark the source region of the eruptions on the disk. The green star in the last panel for the October 28 magnetogram refers to the SE event and coincides with its source region.
