Position of Solar Orbiter, Parker Solar Probe, STEREO-A and Wind projected in the plane of the Heliocentric Earth Ecliptic (HEE) coordinate system. Left: position on 11 July 2020 at 02:30 UT. The position of the radio source is shown as crosses near the Sun. Middle: position on 21 July 2020 at 03:00 UT. The positions of the radio sources from the two events of that day are indicated by coloured crosses near the Sun. Since both events are from the same region, they are superimposed. Right: position on 18 November 2020 at 02:00 UT. The position of the radio sources for the two events of that day are shown as coloured crosses near the Sun. On this day there is a difference between the location of the radio sources from the first event and from the second event. The determination of the radio source location is described in the text. On each plot, dotted lines are used to point the direction of the radio sources.
