DESCRIPTION: Small solar flares\, or microflares (GOES B class and fainter)
 \, are frequent bursts of energy released in the Sun’s atmosphere\, exhi
 biting heating and particle acceleration similar to that of large flares. 
 X-ray observations provide direct diagnostics to study these processes by 
 examining thermal emission from the hot flare loops and non-thermal emissi
 on from accelerated electrons. We present analysis of the X-ray emission f
 rom small solar flares jointly observed with the Nuclear Spectroscopic Tel
 escope Array (NuSTAR) and the Spectrometer Telescope for Imaging X-rays (S
 TIX) on Solar Orbiter\, providing different viewing angles of each event. 
 NuSTAR is a highly sensitive X-ray imaging spectrometer that can directly 
 image the Sun from 2.5 keV using focusing optics. STIX is an imaging spect
 rometer which instead uses indirect optics but has detectors capable of ha
 ndling a wide range of solar X-ray fluxes from 4 to 150 keV. NuSTAR is in 
 Earth orbit\, whereas STIX is orbiting the Sun\, so the two instruments co
 mbined can give different viewing angles of solar X-ray emission\, providi
 ng a clearer picture of the flare’s structure. Combining analysis of NuS
 TAR and STIX’s X-ray spectra\, we can take advantage of their different 
 strengths\, gaining a better understanding of the energy release in solar 
 flares. We present observations of flares from June 2020 (on-disk for both
  instruments) and September 2022 (occulted for NuSTAR but on-disk for STIX
  - allowing us to probe a pre-flare non-thermal coronal source with NuSTAR
  and bright lower atmosphere flare emission with STIX).\nVortragende(r): N
