Thanks, jura; I was actually also watching squadrons of swallows whistling up their evening meal of airborne insects.
Giz and Mush; I'll ponder your words. Thank you, all.
...I've pondered a bit. The sun's rays hitting me on the ground are parallel with the rays hitting the moon, so if the line between dark moon and sunlit moon is tilted back so that the perpendicular towards the sun is well above the horizon, then the sun should also be well above. But it isn't, so I'll have to keep pondering. Thank you.
