The nominal science phase of the mission started in November 2021. The six remote sensing and four in situ instruments on board Solar Orbiter provide high-resolution observation of the solar atmosphere and measure the plasma properties at the satellite. The Solar Orbiter observations allow for the study of the connection between the Sun and the heliosphere. On 13 October 2022, the Solar Orbiter will reach its perihelion 0.32 AU, and on 16 October, it will be in quadrature with Earth with respect to the Sun. As Solar Orbiter moves closer to the Sun-Earth line, we propose to co-observe a single active region with DKIST over multiple days. This will allow us to simultaneously collect some of the highest spatial resolution photospheric, chromospheric (both with the VBI at DKIST), and coronal (with the EUI onboard Solar Orbiter) imaging ever sampled. On top of this, high-resolution spectropolarimetric data sampled by the ViSP and the SPICE instruments will provide context about the local magnetic field and line-of-sight velocities in exquisite detail. Such co-observations will return open-source datasets that will allow researchers to understand better the evolution of active regions (which are, of course, extremely important as the predominant locations where space weather events are driven from) and to probe the flows of mass and energy between different atmospheric layers in unprecedented detail. We propose that these datasets be sampled over 2-3 days, between the 22nd and 27th October 2022."
