6m Es - report from Sweden

6m WSPR came to life at 0940z with a spot of my 1W ERP signal by SM67464 (999km). I am hopeful of more 6m Es spots later.
UPDATE 1110z:  I see I spotted  DK1KW (914km) on 6m WSPR at 1054z. Things seem to be livening up on 6m Es at last. Not before time too.

UPDATE 1230z:  Good to spot an old work colleague on 6m WSPR - G3WKW (134km) at 1152z. We have exchanged spots before on WSPR, even on 2m, usually with the help of aircraft.

UPDATE 1314z:  Yet again 4X1RF (3519km) has spotted my 6m 1W ERP WSPR at a decent -17dB S/N.  This is a LONG way for Es. This is far from unique on 6m as he spotted me a few weeks ago and he spotted me last summer too. Is this really multi-hop Es?

UPDATE 1840z:  Just the single "real DX" 6m WSPR spot today at 1308z by 4X1RF (3519km). I know he has spotted others too, probably with more ERP in his direction than me! Since then, and all day in fact, plenty of GDX spots of others and of me, in my case, out to 103km. Es was there on the band, but it was not plentiful.

UPDATE 2144z:  I have now gone QRT on 6m and 10m WSPR, but will be on again at breakfast time on both bands. I am convinced that the 6m spots by 4X1RF are not multi-hop Es. Looking at his logs, there are no spots of stations at intermediate"hops" at the right times. This may be Es, but I do not agree with the multi-hop hypothesis. Maybe there is some kind of chordal hop Es?
