Hi Jay yes speculation it is but it is interesting to check where the shadow 
is at 100km altitude when the sig comes in. There is also the possibility of 
an E-region hop followed by a D-region hop. The last is unlikely to my mind 
as D-region hops are much more highly attenuated by the photo-dissociated 
electrons and towards late afternoon as the solar angle decreases the 
attenuation increases. But its all hypothetical, as far as I am concerned 
:-))

Good Luck with it all.
