Solar Orbiter/STIX HXR images of eight hard microflares. For each event, the left panel displays the SDO/HMI intensitygram and the pre-flare subtracted SDO/AIA 1600 Å contours (orange) from the Earth’s perspective. The right panel shows the SDO/AIA 1600 Å image closer to the nonthermal peak time reprojected to the Solar Orbiter view, with orange the reprojected pre-flare subtracted SDO/AIA 1600 Å contours. The STIX images are displayed as red (thermal emission) and blue (nonthermal emission) contours. The event number is displayed in the bottom-right corner.
