Nick G0OQK is 98km away in the Chilterns (IO91pp) and he has spotted my 1W ERP 6m signal countless times today. Doppler is very low so I am wondering if this is tropo (generally) NOT involving aircraft? In the next few days Nick will be on TX so I can check here for a lack of multiple traces on the WSPR screen. If there are lots of traces on his signal it will suggest aircraft reflections. If (usually) just a weakish single trace it will suggest tropo.
UPDATE 2250z: No more Es reports from CN8LI since 1918z. Unless things suddenly change, I think the Es here has ended for the day.
