Results are quite coherent with an intense light well seen on the dark
side at a level stronger than the sky background.
I checked with all kind of filters including the polaroid, same presence
with a more intense level for the W29.
Polarisation light ratio on sun was high during the period, planet not far
from the local meridian.
Completely cloudy after 16H00UT.
To-day also cloudy, but may be some holes in the afternoon.
I think a check on the complete day each hour to see if the levels are
modified with the planet position in sky is to be expected seriously.
