AbstractThis paper discusses the potential of future joint hard X-ray solar flare observations between the Hard X-ray Imager(HXI)onboard the Advanced Space-based Solar Observatory(ASO-S)mission and the Spectrometer/Telescope for Imaging X-rays(STIX)on Solar Orbiter.The different viewing perspectives of the two telescopes relative to the Sun will allow us for the first time to systematically study non-thermal hard X-ray emissions stereoscopically.During the 4-years of the nominal mission of ASO-S, we expect to jointly observe about 160 flares above GOES M1 class to systematically study hard X-ray directivity.For about 16 partially limb-occulted STIX flares, we will have observations of the entire flare by HXI.Such observations will enable us to simultaneously study the all-important coronal hard X-ray sources,which are generally lost in the instrument's individual imaging dynamic range, in combination with the chromospheric footpoint emissions.The two different detector systems used in the two telescopes make the relative calibration between the two instruments a key task that needs to be addressed before creditable science results can be published.If an accurate inter-calibration can be achieved using jointly observed flares on the disk, observations with HXI and STIX will provide new and essential key diagnostics for solar flare physics.
