At the current time, 1910z, WA0APC (7012km) was the last to spot my 500mW WSPR on 10m at 1650z. Since then, just Europeans spotting me. It is still just about possible that other USA stations might copy me, although it has been dark here now for 3 hours, so I'd be surprised.
The reports from Germany were very strong, so possibly this was winter Es?
UPDATE 2046z: K9AN (6505km) was the last USA station to spot me on 10m today at 1828z. The last international spots of me on 10m were DK0UG (+1dB S/N) and DK0SC (-11dB S/N) at 1912z. Since then, just local G4IKZ (18km) spotting my 500mW on 10m WSPR.
UPDATE 2230z: Went QRT on 10m WSPR.
