10m WSPR - a disappointing day

Well, what a disappointing day on 10m WSPR! Just a single spot all day! This was from KD6RF (7571km) at 1754z. I re-synced the PC and checked things were OK as until this time I got not a single spot and thought something was wrong at my end. We are seeing reduced 10m WSPR activity, even though conditions suggest more should have been possible.
