Today has been very fruitful on 10m WSPR with plenty of spots by Es of my 500mW beacon. OZ9QV (864km) has spotted me many times. All spots have been by Europeans by Es I think.
UPDATE 1522z: In past seasons I seem to recall more Es from Northern Europe later in the season. This may be incorrect, but perhaps the things that trigger Es are more common in Northern Europe later in the summer?
