You'd better tread carefully, you don't want to sound too flat.

Anna needs a new 'G' string....C flat major."...a coo stick.
Do I sense Don_1's longing for an acoustic guitar? Or another acoustic instrument?
Ah coo stick to your original idea.
I think I meant atmospheric refractionI would have thought that if there was any sort of difference with how the sun appears to moves on the horizon due to refraction, it would appear to move slower at the horizon. If you consider that (according to my sources - the TV show "QI") at sunset, the sun is actually already below the horizon when we see it first touch the horizon, it would mean the image of the sun is taking longer to set than the actual sun.
Since the atmosphere refracts the light around the earth during sunrise and sunset (hence the sun appears there when it isn't) but not at midday.
So if I was watching the sunrise it would appear to travel a greater distance in less time since the curve is decreasing at the same time as it moves.
I hope that is more clear.
Sorry about the very nontechnical language.
I'm very displeased that this thread has been taken so off topic that the actual topic is no longer being addressed.
If you really want to see the past, why not take a "selfie" on your smartphone?
