摘要: The Solar X-ray Monitor (abbreviated as XSM) on board India's Chandrayaan-2 mission is designed to carry out broadband spectroscopy of the Sun from lunar orbit. It observes a star and measures spectrum every second in soft band 1 - 15 keV with an energy resolution better than 180 eV at 5.9 keV. primary objective XSM provide incident solar for fluorescence experiment orbiter, which aims generate elemental abundance maps surface. However, observations can independently be used study well. was launched 22 July 2019, began nominal operations, orbit, September 2019. in-flight observations, so far, have shown that its spectral performance has been identical ground. Measurements effective area ground calibration were found require some refinement, carried using different angles. also sensitive enough detect activity well below A-class. This makes investigations microflares quiet corona feasible addition evolution physical parameters during intense flares. article presents instrument discusses specific science cases addressed XSM.
