Absolutely.Namely the moonlight cannot be reflected sunlight.
Only one reason really, the Sun emits no visible light to be reflected!Two reasons for that:
Last night we had an unusually clear sky, and the bright Moon was up. I could see very well with no outside lights on, and looking at a handy spray can with different size letters on it, I could easily read the letters down to the bold, 1/4 inch high ones. One of those nights you could easily drive without headlights.
So I was wondering how much brighter it would be on the Moon with a full disk Earth in the night sky, given its size and albedo. By NASAs calculations there would be 67 times more light, but as no direct measurements of light levels were taken on the Moon, we don't know if their calculations are correct. Similarly, no measurement of the Moons brightness has been taken from outside of Earths atmosphere, so we don't know how much of the Moonlight we see is generated by Earths atmosphere.
