Locations of planets and spacecraft in the inner solar system on April 20, 2020, the day the CME arrived in the vicinity of Earth. The trajectory of Solar Orbiter (SolO) is shown as an orange dashed line and PSP denotes the location of Parker Solar Probe. The large black arrow indicates the approximate propagation direction of the CME and the colored segments next to STEREO-A show the fields of view of the remote sensing instruments COR1/COR2 (green), HI1 (blue), and HI2 (red). The inset shows a zoomed-in view of the relative positions of Earth, the Moon, and the Lagrange point L1, where the Wind spacecraft is located.
