Overview of Solar Orbiter observations. Temporal coverage of the data and the corresponding cadence from the four remote-sensing instruments on board the Solar Orbiter spacecraft used in this study. In the case of STIX data, the darker red line denotes the observations at 0.5 s cadence while the lighter red line indicates 2 s cadence. The background shaded curve is the sun-as-a-star time series of the soft X-ray flux in the 1–8 Å filter on the Geostationary Operational Environmental Satellite. The right hand side ordinate gives the flare classification scale.
