SOLARNET Conference: The Many Scales of the Magnetic Sun

The ESA and NASA Solar Orbiter mission started its nominal mission phase in November 2021. Three perihelions and nine remote sensing windows have been successfully completed, providing data from all the instruments on board the spacecraft. The Polarimetric and Helioseismic Imager (SO/PHI), one of Solar Orbiter's remote sensing instruments, is the first magnetograph to observe the Sun from outside the Sun-Earth line. Most of the data acquired by the High Resolution Telescope (SO/PHI-HRT) has been placed on the Solar Orbiter Archive (SOAR) and are available to the whole scientific community. The excellent polarimetric sensitivity of the instrument and the absence of aberrations induced by the Earth’s atmosphere provide an ideal scenario to study the photospheric dynamics and magnetism of the Sun. The talk will introduce the SO/PHI-HRT instrument and describe the data that has been released so far. The processing of the data will also be shortly discussed. We will then present some of the scientific cases that have been addressed, either with standalone observations performed by the instrument, or with data combined with observations made by other Solar Orbiter instruments, or with data gathered by instruments on other spacecrafts or on ground.
