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.

这个项目聚集了一些主要的IR日冕实验人员，共同努力在1998年2月的日全食时从飞机平台上发起一场决定性的运动。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，为日冕研究增加诊断能力；(2)进行红外日冕辐射的光度测量，以明确由f -日冕组成的行星际尘埃的热发射和散射的相对作用；(3)测量日冕信号中弗劳恩霍夫谱线的谱移，以确定太阳附近行星际尘埃的运动，并了解先前报道的开普勒轨道运动的变化；(4)利用线廓线测量方法，研究了1994年日蚀观测到的He I 1083 nm外日冕辐射。
