This opening is quite common on 10 and 15M.  It has given me OH/SM/LA  and 
occasionally UA multipliers a number of times the normal opening earlier in 
the day did not go that far north.  I always make a point of looking for it 
when I need these multipliers.

This year it gave me OH and SM on both modes and TF on phone. I didn't work 
any other Europeans this year in the 10M contest. OH6NIO was a solid S9 
when he called me, and that may have been the strongest signal I ever heard 
this path. Most of the time the signals are very weak, but workable.

K9LA wrote about it a few years ago in his propagation column in World Radio.

There is a similar opening with northern North America being at the eastern 
end.  Unfortunately the other end is in zone 23 and I have only heard 
activity on this path once.
