Early 10m Es

I did a resync of the 10m WSPR beacon before breakfast. There was early Es on 10m WSPR this morning with Danish stations spotting my 500mW 10m WSPR beacon.

UPDATE 0954z:  Es spots from all over Europe now.

UPDATE 1028z: Some of the 10m spots are from Holland. If Es, this is very short skip suggesting Es possibly as high as 2m. It is possible these are tropo or aircraft reflections.  I think Es is more likely as aircraft reflections are usually accompanied by lots of Doppler and the aircraft have to be in the right place for quite a long time with WSPR.
