SDO/AIA 193 Å images and in situ SW plasma measurements for CIR no. 2 recurring five times. Left: EUV images showing CHs extracted via CATCH and identified as the origin of HSS measured in situ. Right: in situ SW bulk speed (red) and density (blue). The odd panels show SW data obtained from the OMNI database, the even panels depict MAVEN data. The density peak and the end time of the event are shown by the black dashed vertical lines. In the top right corner of the profiles the heliographic longitude Θ_HG and the heliographic latitude ϕ_HG of the planet is given.
