侧倾角度调节调光Starlink卫星
Roll Angle Adjustment Dims Starlink Satellites
摘要：
2020年，Starlink卫星在轨道停放和轨道提升期间的亮度因运营商修改其方向而显著下降。变化前的平均视星等为3.90 +/- 0.18，而变化后为5.69 +/- 0.06。当震级调整到1,000公里的标准距离时，平均值为4.86 +/- 0.16和7.31 +/- 0.05。在标准距离上的差异表明，调整了滚转角的航天器比以前的航天器平均暗90%。
英文摘要：
The brightness of Starlink satellites during orbit parking and orbit raising decreased significantly in 2020 when the operator modified their orientation. The mean apparent magnitude before the change was 3.90 +/- 0.18, while afterward it was 5.69 +/- 0.06. When magnitudes are adjusted to a standard distance of 1,000 km the means are 4.86 +/- 0.16 and 7.31 +/- 0.05. The difference at the standard distance indicates that spacecraft with adjusted roll angles are 90% fainter on average than the earlier ones.
