Snapshot of the radially scaled solar wind density from the ENLIL simulation in the ecliptic plane at 06:00 UT on 2022 January 20. The black and white dashed lines represent the IMF lines and the black contours track the ICMEs. The white lines correspond to the HCS, which separates the regions with opposite magnetic polarity, shown in blue (negative) or red (positive) on the outer edge of the simulation region. The yellow circle indicates the flank arrival of an ICME to Solar Orbiter (details given in the text). Credit: Community Coordinated Modeling Center (CCMC).
