Abstract

We report a brief result of comparing high spatial resolution images of the innermost corona observed at several visible wavelengths and in soft X-rays. The optical images were obtained during a total solar eclipse, at around 19:00 UT on 11 July 1991, by a Kyoto university team. The observed wavelengths are three coronal forbidden lines (FeXIV:530.3nm, FeX:637.4nm, and CaXV:569.4nm), HI:656.3nm, and continuum arround 610.0nm. (Kurokawa et al., 1992, Takeda et al., 1994) Soft X-ray images were taken by the Harvard-Smithsonian group utilizing the Normal Incidence X-ray Telescope (NIXT), from 17:25 to 17:30 UT. It is sensitive to the temperature from 1M to 3MK, due major contribution from MgX and FeXVI coronal lines. (Golub et al., 1989)
