以前的太阳紫外线变化的卫星测量显示一致的太阳周期辐照度的变化仪器的不确定性，也显示一致的光谱依赖旋转和太阳周期的变化。经验太阳辐照度模型产生的太阳紫外线变化与观测数据吻合得很好。太阳辐射和气候实验（SORCE）光谱辐照度监测器（SIM）和太阳恒星辐照度比较实验（SOLSTICE）仪器的最新紫外辐照度数据涵盖了第23周期下降阶段的170 nm，显示太阳变化大大超过了以前的测量和预测的辐照度变化。SIM和SOLSTICE变化的光谱依赖性不同于以前的结果。然而，来自SIM和SOLSTICE紫外线辐照度数据的短期太阳变率与其他同期太阳紫外线测量和以前的结果一致，表明太阳物理学没有变化。SORCE的长期紫外线结果可以解释为早期在轨测量期间仪器响应变化的校正不足。
Previous satellite measurements of solar UV variability show consistent solar cycle irradiance changes within instrumental uncertainties, and also show consistent spectral dependence for both rotational and solar cycle variations. Empirical solar irradiance models produce solar UV variations that agree well with observational data. Recent UV irradiance data from the Solar Radiation and Climate Experiment (SORCE) Spectral Irradiance Monitor (SIM) and Solar Stellar Irradiance Comparison Experiment (SOLSTICE) instruments longward of 170nm covering the declining phase of Cycle 23 show solar variations that greatly exceed both previous measurements and predicted irradiance changes over this period. The spectral dependence of the SIM and SOLSTICE variations differs from previous results. However, short-term solar variability derived from SIM and SOLSTICE UV irradiance data agrees with other concurrent solar UV measurements and previous results, suggesting no change in solar physics. The SORCE long-term UV results can be explained by undercorrection of instrument response changes during early on-orbit measurements.
