One of the main scientific opportunities offered by SO is stereoscopic observation in conjunction with Earth- or near-Earth observatories. The difference in viewing angle bears important consequences on the possibility of comparing and merging such observations, as the optical path from the two viewpoints can be very different. In order to assess the general feasibility of stereoscopic observations, a thorough comparison of the spectropolarimetric properties of Hinode/SOT-SP and SO/PHI-HRT is necessary.;;Coordinated observations with the Solar Orbiter (SO) Polarimetric and Helioseismic Imager (PHI) High-Resolution Telescope (HRT), close to SO perihelion in the second remote sensing window (RSW2) of the first orbit of SO Nominal Mission Phase (NMP) that will take place in early March 2022.
