WSPRing The Terminator

At the moment (early November), the terminator runs almost identically at MW and easternmost EA8, providing ideal conditions to test propagation along the 'grey line'.

Luckily, EA8/LA3JJ is often on the island of Fuerteventura, running a good WSPR suite on many frequencies, including 5MHz.

Here are the results, together with some annotations on the main features and how they relate to the changing time of day (click to enlargen image).  For once, the geomagnetic conditions were very quiet (Kp 1-2)!
