太阳最近经历了一段明显缺乏大耀斑和太阳黑子等重大活动的时期，这是自半个世纪前太空时代到来以来从未有过的。太阳活动的一个广泛使用的衡量标准是太阳软X射线发射量，但直到最近，这一直低于X射线监测地球静止运行环境卫星（GOES）的阈值。因此，迫切需要更灵敏的仪器来记录该范围内的太阳X射线发射。
考虑到这一需要，在2009年1月30日发射进入近极轨道的俄罗斯“太阳活动近地复杂轨道观测”（日冕-光子）方案第三个航天器上的太阳望远镜/分光仪TESIS仪器包中包括了一个称为X射线太阳光度计（SphinX）的高灵敏度分光光度计。SphinX测量的X射线波段类似于GOES的长波通道。
The Sun recently underwent a period of a remarkable lack of major activity such as large flares and sunspots, without equal since the advent of the space age a half century ago. A widely used measure of solar activity is the amount of solar soft X-ray emission, but until recently this has been below the threshold of the X-ray-monitoring Geostationary Operational Environmental Satellites (GOES). There is thus an urgent need for more sensitive instrumentation to record solar X-ray emission in this range.
Anticipating this need, a highly sensitive spectrophotometer called Solar Photometer in X-rays (SphinX) was included in the solar telescope/spectrometer TESIS instrument package on the third spacecraft in Russia's Complex Orbital Observations Near-Earth of Activity of the Sun (CORONAS-PHOTON) program, launched 30 January 2009 into a near-polar orbit. SphinX measures X-rays in a band similar to the GOES longer-wavelength channel.
