论文摘要
对于许多天体物理实验和地面观测，对天空特征的评估起着基本作用。在太阳能物理学中，这种观察结果的主要要求是非常低的天空亮度值，即不到太阳能磁盘亮度的一百万个。很少有地方对地面，放弃冠状的测量值匹配。候选冠状网站是南极洲的圆顶高原。在本文中，我们在圆顶C上显示了圆顶C的第一个结果，以及在夏季XXXXIV和XXXV探险期间，圆顶C，Antarctica（3300 m）上的意大利 - 联邦Concordia站的极端太阳可冠状的南极计划实验（Escape）。天空亮度测量是用内部培养的南极冠状动脉 - 南极进行的。在最佳的大气条件下，圆顶C的天空亮度已达到1.0至70万个太阳能磁盘亮度的订单。
The evaluation of sky characteristics plays a fundamental role for many astrophysical experiments and ground-based observations. In solar physics, the main requirement for such observations is a very low sky brightness value, that is, less than one-millionth of the solar disk brightness. Few places match such requirement for ground-based, out-of-eclipse coronagraphic measurements. A candidate coronagraphic site is the Dome C plateau in Antarctica. In this paper, we show the first results of the sky brightness measurements at Dome C with the Extreme Solar Coronagraphy Antarctic Program Experiment (ESCAPE) at Italian-French Concordia Station, on Dome C, Antarctica (3300 m) during the summer XXXIV and XXXV Expeditions of the "Italian Piano Nazionale Ricerche Antartiche" (PNRA). The sky brightness measurements were carried out with the internally-occulted Antarctic coronagraph - AntarctiCor. In optimal atmospheric conditions, the sky brightness of Dome C has reached values of the order of 1.0 to 0.7 millionth of of the solar disk brightness.
