Description

The backbone of Solar Orbiter coordinated observations is constituted by the so-called SOOPs (Solar Orbiter Observing Programs), which are designed to address specific science objectives of the mission.
This contribution focuses on the SOOP identified as "R_FULL_HRES_HCAD_Density-Fluctuations", which has the primary objective of studying density fluctuations in the middle or extended corona. This SOOP has been run regularly since the first orbit of the nominal mission in March 2022. The program typically involves high-cadence observations with the Metis coronagraph and the Full Sun Imager (FSI) of the Extreme Ultraviolet Imager (EUI). In specific instances, the SPICE spectrograph and the two High Resolution Imagers (HRI) of EUI have also been employed to provide complementary data closer to the solar surface.
In this work, we present an overview of the observations carried out within the framework of this SOOP. Furthermore, we illustrate highlights of the main results obtained.
