Hi Terry that is a fairly common picture with joe. If you want some fun, 
have a look at a geo program like geoclock which shows the sunrise shadow. 
Ideally you want one that will allow you to declare an altitude......then 
you want to enter 100km (I think some versions of Geoclock allow this) Then 
look at the position of the shadow around 0600 and 0630. I think you will 
find that the shadow is aound 1/4 of the way into the path. This suggests to 
me that the 2nd ionospheric hop point of the signal has been washed out by 
the solar radiation. The remaining signal maybe a weak one-hop (!) or 
possibly one night hop followed by two daytime D-layer hops. I think this is 
unlikely, but dont role it out, but D-layer daytime skywave is usually weak 
in the early morning.

Interesting stull this LF propagation :-))

Alan G3NYK.
