Position of planets and spacecraft within 1 au from the Sun on 2021 October 9 at 06:30 UT. The source region of the CME eruption associated with an M1.6-class flare is indicated with a triangle symbol on the surface of the Sun. Earth and the spacecraft have been connected to the Sun through the nominal Parker spiral for a solar wind speed of 400 km·s⁻¹. The same spiral connects the source region of the eruption to the heliosphere. The orbits of Mercury, Venus, and Earth are also shown.
