Hi Steve:

      I think there are several things going on as to why you are hearing EU 
now. First of all,
 the stations you mention, ES1 and OM are some of the areas of EU that are in 
the more 
Northerly directions from here. ES1 is on 17 Degree path and OM is on a 26 
degree path
 from here.
     The auroral polar absorption for the last week or more has been lower for 
longer periods
 of time than I have ever seen it before.
 When it drops way down we can receive the more northerly signals through it. I 
monitor it many
 times every day on . The ES1 you mention 
was a true
S9 here on my TX vertical. And he was very strong on my 0 Deg., 22.5 Deg., and 
30 Deg.
 antennas. Spot on I think.
     Almost all of the signals I have received from EU in the last week or so 
have been strongest
 on their true bearing. As such I have observed no evidence of any skewing. 
Several of my RX
 antennas are shortened vertical arrays which quickly lose their directivity on 
high angle signals.
I have seen little, if any sign of high angle signals recently as well.
     I think the quiet sun is responsible for low absorption and good 
propagation to the North of
your mountain.
