Is there a good/coherent explanation of the obseration data in this 
message that came across the refelctor? 

I'm (forgive the pun) in the dark on this...

Thanks,

Wheather is not permitting any observations in Western Europe for
the moment, so thanks Walter for your observation !

The flash period IS still GOING DOWN !  We need to follow it as
regular as possible.
Also don't forget to take a look at 91-  7 B.
