太阳日冕的成像和光谱学，加上偏振测量，是目前唯一可用的工具，可用于捕获在太阳边缘以上最初几个太阳半径内造成日冕加热和太阳风加速的物理过程的特征。随着最近探测器技术和图像处理技术的改进，在日全食期间对日冕禁戒线进行的宽带白色光和窄带多波长观测开始产生关于日冕结构热力学和磁性的新观点。本文概述了这些独特的能力，到目前为止，已经可行的主要是在自然日全食观测。这项工作还提请注意，利用月球边缘掩星的太阳盘日冕测量，大大增加与月球轨道观测站日食观测的频率和持续时间的令人兴奋的可能性。
Imaging and spectroscopy of the solar corona, coupled with polarimetry, are the only tools available at present to capture signatures of physical processes responsible for coronal heating and solar wind acceleration within the first few solar radii above the solar limb. With the recent advent of improved detector technology and image processing techniques, broad-band white light and narrow-band multi-wavelength observations of coronal forbidden lines, made during total solar eclipses, have started to yield new views about the thermodynamic and magnetic properties of coronal structures. This paper outlines these unique capabilities, which until present, have been feasible primarily with observations during natural total solar eclipses. This work also draws attention to the exciting possibility of greatly increasing the frequency and duration of solar eclipse observations with Moon orbiting observatories utilizing lunar limb occultation of the solar disk for coronal measurements.
