Ecliptic plane projection of selected spacecraft. Filled and open squares (triangles) mark locations of Solar Orbiter (Parker Solar Probe, PSP) on 2022 March 3 at 14:16 UT and March 5 at 23:55 UT, respectively. A filled diamond and filled circle mark locations of STEREO-A (A) and the Earth on both dates, respectively. The arrows indicate the longitudes of the solar source at onsets of type III radio bursts associated with injections #2 and #5. Solid and dotted Parker IMF lines are at onsets of type III radio bursts in injections #2 and #5, respectively. The Parker IMF lines were determined from measured 1 h averaged solar wind speeds. It is important to note, however, that for injection #2, the PSP solar wind speed is not available, and the IMF line is for a nominal solar wind speed of 350 km s⁻¹.
