An interesting aspect of this is that the speed of the sun is about the same as a Vulcan flying westwards at M0.84 (480kts) at around 40,000 at around 55N. This meant that on trips from UK to Goose Bay you often had the same figures coming up in successive astro calculations. I seem to remember it also worked against us one day when we were followed for some time by an eclipse of the sun. I’ll try and find the date in my logbook so some keen fellow can check if I’m imagining things again.
