10m WSPR TX (again)

Yet again, I am on 10m WSPR TX (500mW) with my little W5OLF WSPR beacon hoping for more Es. Yesterday there were 16 unique spots. The day before there were 40 uniques. So far today nothing! Is the main Es season drawing to a close?

UPDATE 1454z:  6 unique spots today, so far, of my little 500mW 10m WSPR beacon from all over Europe. There does seem to be less Es though.

UPDATE 1740z: Still just 6 unique spots on 10m WSPR. Several spots from OZ9QV (864km) - thank you.
