论文摘要
每天对太阳能光球和色球球体的每日全盘观察开始于1908年的Meudon天文台。在审查了科学环境和历史背景之后，我们描述了自2018年以来新版本运行的新版本的仪器特性和功能。主要变化是整个Solar Disk提供3D数据集团全线配置文件的系统性记录。光谱和空间采样都得到改善。在固定波长处的太阳的经典2D图像仍在传递。我们总结了在线数据的不同处理水平，并简要回顾了新的科学观点。
Daily full-disk observations of the solar photosphere and chromosphere started at Meudon Observatory in 1908. After a review of the scientific context and the historical background, we describe the instrumental characteristics and capabilities of the new version operating since 2018. The major change is the systematic recording of full line profiles over the entire solar disk providing 3D data cubes. Spectral and spatial sampling are both improved. Classical 2D images of the Sun at fixed wavelength are still delivered. We summarize the different processing levels of on-line data and briefly review the new scientific perspectives.
