EIS observed the highest temperature lines of FeXXIII263.76A, FeXXIV192.10A, 255.10A in the EIS observing
wavelengths during a C4.2 flare occurred on 16-Jan-07, as well as an FeXVII line at 254.83A. The raster scan of
the flaring area took place during 2:36 - 2:41 UT nearly at the maximum phase of the flare. Comparing a
monochromatic FeXXIII raster image with the other high spatial resolution images taken by the instruments on
board the Hinode and those by Nobeyama Radio Heliograph, electron precipitation cites are indentified. Foot
points with fast chromospheric evaporation are compact at the size of a few arcseconds, and the turbulence still
remain around the top of flaring loops. Down flows are also seen in the lower temperature lines just outside the
flaring loops.
