6m QRP FT8 (Saturday)

My 5W to a V2000 vertical antenna was turned on at about 0845z: 

UPDATE 1409z:  26 spots of me so far. Yet again, more northern stations see to be most prominent. This puzzles me: it seems a pattern that repeats towards the end of every Es season. I would be interested to hear any theories as this is too common to be just random.

UPDATE 2043z: 33 stations have spotted me today. If some were Es, it is now less widespread and strong. QRT.
