I know it sounds strange,, but there you go..
Here's another strange one...
According to Baird T. Spalding, in his book series "The Life and Teaching of the Masters of the Far East", Jesus was reported to have told of the true nature of the Sun:
"If we take the science of things, we know there is a legend told here that all the heat and light and many other natural forces are contained right within the earth itself. The sun, of itself, has no heat or light. It has potentialities that draw the heat and light from the earth. After the sun has drawn the heat and light rays from the earth, the heat rays are reflected back to the earth by the atmosphere that floats in the ether. The light rays are drawn from the earth in about the same manner and are reflected back to the earth by the ether. As the air extends only a comparatively short distance, the effect of the heat rays varies as you leave the earth's surface and ascend toward the outer limit of the atmosphere. As the air becomes less dense, there is less reflection; consequently as you ascend into the higher altitudes the heat becomes less and the cold increases. Every heat ray, as it is drawn out and reflected, drops back to the earth, where it is regenerated. When you have reached the limit of air, you have reached the limit of heat. It is the same with the light rays. They are drawn from the earth and reflected back by the ether. As this ether extends much farther from the earth than the air, the light rays extend much farther before they are all reflected. When you have reached the limit of ether, you have reached the limit of light. When you have reached the limit of heat and light, you have reached the great cold. This cold is far more solid than steel, and it presses down upon the ether and the atmosphere with almost irresistible force and holds them together."
Personally, I don't think the Sun heats the Lunar surface, but then I'm a strange one too.

Oh, and they never measured total Solar irradiance during any of the Apollo moon landings.
