Position of PSP (red circle) and STEREO-A (blue circle) in the ecliptic plane during the first CME (upper row) and second CME (lower row). The gray region represents CME #1 (upper row) and CME #2 (lower row) using positions calculated in Sects. 4.1 and 4.2 (Tables 2 and 4) and widths fromSect. 4.6. The Sun and Earth’s positions are represented by the orange and green circles, respectively.Left panels (a and c): first observation of each CME in WISPR-I FOV, and right: last observation on HI-1. The approximate FOV of HI-1 and WISPR-I are represented by the red and blue lines, respectively. The dashed line represents the spacecraft position in an arbitrary future point in its orbit.
