Reports from CN8LI have been coming in consistently all afternoon. I assume the propagation is Es but this very non-sporadic! I suppose it is just conceivably single hop F-layer, but I think Es is more probable. Now if only someone another 1000-2000km further south was on too so multi-hop Es into Africa was a possibility. Later in the Es season, multi-hop Es becomes more likely into S.America, the Caribbean and N.America.
At 1806z CN8LI is still spotting me well (-1dB S/N).
UPDATE 2125z: CN8LI's last 6m spot of me was at 1854z (+6dB S/N) and this appears to be the last today. Just G4IKZ spotting me now, lot of times!
UPDATE 2200z: finally closed down at 2145z with just G4IKZ spotting me all evening.
