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.
