Three-dimensional view illustrating the CME #1 at 2021 November 20 15:00 UT. For clarity, we depict here only the CME portion below 15 R_⊙. The gray lines correspond to the CME legs. The tubular portion of the CME is not represented as it is entirely above 15 R_⊙. The red circle indicates PSP’s position at 15:00 UT. Blue circles indicate the spacecraft location in the following hours, as indicated by the labels. The orange circle represents the Sun’s location (not to scale). The coordinate system used here is HEEQ.
