Although the 5B4ADA/N7UA QSO was LP, I and others have previously worked
northern EU stations at your sunset/our sunrise on 160m this time of the
year, but it was not long path. The stations could only be heard/worked
from here by beaming the short path.
If you check your grayline map, you'll see that it is an all-darkness
path from the USA west coast to northern and eastern EU via the normal
short path around the winter solstice during my sunrise.
