With 17 stations already spotted on 6m FT8 and 2 stations already spotting my 10m WSPR this morning, I can only conclude that the Es season is not over!
Yes, things may be more sporadic, but for those sticking with it, there is still Es activity around. Often lack of activity is mistaken for "dead" bands when actually there is propagation. Look how often 11m CB is busy when 10m seems quiet.
UPDATE 1208z: 30 stations spotted so far on 6m FT8 RX. 4 stations have spotted me on 10m WSPR TX.
