论文摘要
我们发现，在Galex任务10年的生命中，量表的分散紫外线背景有所不同。这些变化仅在Galex的近硫酸酯带中显而易见，并且由于太阳能通量的亮度变化，最有可能与黄道光的变化有关。 NUV中的变化可能高达200个光子单元，约占十二叶光的15％，占NUV弥漫性辐射的<10％。对Galex的远硫酸群带没有影响。进一步的工作将需要专门为研究该组件而选择的更好的观察结果，并且很难获得。
We have found variations in the diffuse ultraviolet background on the scale about 10 days over the 10 year life of the GALEX mission. These variations are only apparent in the near-ultraviolet band of GALEX and are most likely related to variations in the zodiacal light due to brightness variations of the solar NUV flux. The variations can be as high as 200 photon units in the NUV, amounting to about 15 % of the zodiacal light or < 10 % of the total NUV diffuse radiation. There is no effect on the far-ultraviolet band of GALEX. Further work will require better observations chosen specifically for the purpose of investigating this component and will be difficult to obtain.
