Interesting conditions this weekend. On Friday I received N1BUG's 
133kHz WSPR2 transmissions a couple of times, on Saturday night he 
came through an amazing 23 times between 2326 and 0644UTC. 

But last night (Sunday) he did not appear to be received by any 
European stations. Instead, I decoded one transmission by K3RWR, and 
I believe I was the only European to do so. 

That was quite a big change in conditions. Looking at the propagation 
data at Boulder, there seemed to be no significant change that might 
explain it. Do the propagation gurus have any thoughts?
