EA1KV (1304km) has spotted me twice, so far, on 6m by Es. I am sure there many be other Es stations this lunchtime and teatime on 6m WSPR. Apart from this Es opening, all spots (given and received) have been G stations - G3ZJO (79km), G8EPQ (77km) and G6IMT (65km).
UPDATE 1600z: Teatime and the Es is back again on 6m. EA1KV (1304km) is again spotting my 1W ERP on 6m WSPR.
UPDATE 2002z: No further 6m Es WSPR spots seen here this evening.
