Elliptical path trace for GW3LEW

The trace shows a Westbound ( positive Doppler )aircraft which crosses the maim trace very close to 18:06. This seems to indicate that the craft had virtually zero relative velocity to me at that point ( due North on Green one?), and also that both GW3LEW and the aircraft were both located on a common ellipse at that point as well. This could be verified aurally by hearing the " chuff-chuff " amplitude interference pattern approach zero at that point.

Further HF multiple aircraft reflections may be seen on GW4BLE ( 22km cross polarised )one approaching ( me ) and two or three receding, all at virtually constant relative velocity to me.
