[Laser] Lunar Eclipse #3

Regrettably one very bad weather is  foreseen during the eclipse in France.
The flash beacon is a very good  idea.
It seems to me to have a little chance to detect it, the pulse power  must be 
very over.
The moon curvature will enlarge the pulse and will reduce  strongly the peak 
value.
To have a little chance to detect something, the  good way could be to sample 
the signal with a very precise clock synchronic with  your TX flash rate and 
the expected pulse flying time.
With a very long  averaging between "out time pulse signal" and "expected 
pulse in time signal" a  cyclic variation could be find?
However I prepare also my APD infrared  receiver.
The PSU can be adjusted near the Geiger point and I will use a very  narrow 
infrared filter near 900 nm.
A threshold detector can extract every  pulse just at the the noise pulses 
level.
It is rough but I have not better  device for narrow pulses for the moment.   
 
With a little  luck it will have a clear period between the clouds here...
