Infrared Eclipse Observations of the Solar Corona

该项目聚集了一些主要的红外日冕实验人员，共同努力在1998年2月日全食时从飞机平台上发起一场决定性的战役。 目标有四个方面：（1）调查中红外光谱区是否存在日冕发射线，以增加日冕研究的诊断能力;（2）对红外日冕辐射进行光度测量，以确定构成F日冕的行星际尘埃的热发射和散射的相对作用;（3）测量日冕信号中夫琅和费线的光谱位移，以确定太阳附近行星际尘埃的运动，并了解以前报道的开普勒轨道运动的变化;（4）利用谱线轮廓测量方法研究了1994年日食时外日冕中He I 1083 nm辐射。

This project gathers some of the principal cast of IR coronal experimenters in a concerted effort to mount a decisive campaign from an aircraft platform at the total solar eclipse of February 1998. The objectives are fourfold: (1) survey the intermediate infrared spectral region for the presence of coronal emission lines, to add diagnostic capability in coronal studies; (2) conduct photometric measurements of the infrared coronal radiance, to specify the relative roles of thermal emission and scattering from the interplanetary dust comprising the F-corona; (3) measure the spectral shift of Fraunhofer lines in the coronal signal to determine the motion of interplanetary dust near the sun, and understand previously reported variations from Keplerian orbital motion; and (4) study the He I 1083 nm radiation observed at the 1994 eclipse in the outer corona by means of line profile measurements.
