Hey guys. I was wondering. On tonight's APOD, if you look real close, you can see that underneath most of the clouds the sea is a slightly lighter shade of blue. The shape of the lighter-blue blotches seem to be about what I would expect from a reflection of the cloud. Of course, you can see the cloud's shadows too. I was wondering, are they indeed reflections?
