Where Has the Earthshine Gone?
image by " rel="nofollow Peter Rosén, Stockholm, Sweden
The LPOD of May 22 about "Our daily moon" really touched me and many others as we reconized a strong and life-long "daily desire to connect to the Moon". Before setting off to work, I first have to locate the moon in the morning sky. In the evening I just have to watch the moon shining above the city or setting in the evening twighlight before going to bed. So I did yesterday shortly before midnight when I captured a beautiful crescent moon setting behind the rooftops of Stockholm. What puzzles me is that there is absolutely no visible earthshine in my pictures; even when stretching the contrast... nothing! At this phase it's usually very prominent as in my image LPOD image of March 10 2011. Other " rel="nofollow photographs taken from other places the day before show a strong earthshine even through the high clouds. I thought that the explanation for earthshine was quite straightforward but now I wonder what other factors are involved other than the relative position of the Sun, Moon and Earth with its reflective cloud layers?
