it should always be in view should it not?
No.
1 cloud in the sky can fully obscure the sun's rays.
One cloud? the sun produces 6.89 x 10
33 lumens. 6,890,000,000,000,000,000,000,000,000,000,000,000. a CANDLE on a hill can be seen at ten miles and is ONLY 90 lumens, a percentage of the sun so small a calculator give 0 as percentage. And you think clouds would provide darkness?
I won't even breach the subject of cloudless nights.
