proposal
LANL's ALEXIS satellite, operating since 1993, is scanning the ant-solar
hemisphere of the sky with 6 multilayer mirror telescopes. Each telescope
is tuned to one of three bandpasses centered at 130, 176, or 186 Angstroms.
Two of these three bandpasses overlap two of the EIT telescope bandpasses.
The Moon is the brightest EUV source in the sky observed by ALEXIS from reflected
solar EUV radiation.

We would like to correlate the observed EUV flux from the Moon with the
total output from the sun as observed by EIT in its bandpasses. The scientific
goals for such a study would be to 1) determine a true Lunar EUV albedo curve
as a function of Lunar phase, and 2) aid in providing out of bandpass sensitivity
limits for the ALEXIS telescopes. The EIT measurements of the 304 Angstrom output
flux from the Sun could also aid in determining the sensitivity
of the ALEXIS telescopes to off-bandpass geocoronal diffuse radiation.
