Distributions of the shock waves recorded by the SWA-PAS and MAG instruments in 2023 along the SolO trajectory compared with the X-, M-, and C-class solar flares obtained from the STIX Data Center. The dark dots in panels a and b indicate the daily average (UTC ≈ 12:00) spacecraft location according to the Solar-MACH catalog (https://solar-mach.github.io), with a time step of 1–5 days. The top panel shows the moments of registering the shock waves for QF1 in the form of spheres of different diameters; the middle panel displays the same information as Panel a, but for QF2. The diameters of the spheres were proportional to the QF1 and QF2 values listed in Table A1. Panel c shows the time points at which different-class X-ray flares were recorded.
