Es looks promising in the east of Europe, but I have not yet seen evidence here.

UPDATE 1501z: Plenty of 6m Es evident in western Europe.
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

UPDATE 1501z: Plenty of 6m Es evident in western Europe.
My 2.5W 6m FT8 to the V2000 vertical omni antenna is turned on. So far just 5 G stations.
UPDATE 1046z: 22 stations have spotted me including 2 in Hungary and one Scandinavian that I assume are by Es.
They are about the size of a large dog.
Since coming home, I am now on 630m QRP again (10mW ERP from the earth-electrode "antenna" in the ground) and expect to stay on overnight. Already spots by 2 stations.
Since returning home this afternoon, I have been on 10m WSPR with 500uW (0.5mW).
UPDATE 2038z: No spots.
My 17m QRP FT8 (about 4W) was turned on at about 1618z. Within a few minutes, I was spotted by 33 stations, See map.
