X-ray observations of the flare associated with the prominence eruption on 15–16 February 2022 from different vantage points. The relative positions of Solar Orbiter and Earth together with the estimated location of the flare associated with the eruption are shown on the left. The X-ray emission measured by XRS aboard the Earth-orbiting GOES spacecraft is shown in the top-right plot. No enhancement in emission is seen, confirming that the flare was completely occulted as seen from Earth. The Solar Orbiter/STIX observations in four different X-ray bands are shown in the bottom-right plot. Given the position of Solar Orbiter, STIX has a better view of the flare above the limb, and clear X-ray signatures can be seen at energies up to 28 keV.
