Last night I observed Venus visually and via CCD in a dark blue sky (it's now
too close to the Sun to be observed against a black sky at reasonable altitude),
looking for any illumination of the dark side,but saw none. With CCD I tried
with every colour filter and none,monitoring the overexposed image for any sign
of the Ashen Light. Here is the IR 742nm image. Seeing was poor.
