Back-mapping example for Solar Orbiter data. (Top) Solar Orbiter orbit (blue line) in the Heliographic Stonyhurst frame together with the orbit of Parker Solar Probe and the location of the Solar Dynamic Observatory. The orbits have been plotted within ±80 days around the time of the high-speed stream observed in Solar Orbiter. (Bottom) Back-mapped points from the high-speed stream that was observed from Solar Orbiter on 13/05/2021 (blue stars), the background is the AIA 193 Å synoptic map.
