The only place I have found a reference to moonlight being septic - to any degree - is in Earth Not a GLobe - Chapter XI.
Out of curiosity, I have searched the web via several search engines, and via the campus Library system and have uncovered nothing regarding the moon's light having septic effects. Since this is such an easy experiment to perform, I will try it out myself next full moon we get that I'm not swamped. I'd think our upcoming I could do so.
There are many, many studies performed trying to define whether or not the moon causes an effect on people. Most of them concentrating on the fact that since the moon causes tidal / gravitational issues, and we are such a high percentage of water ourselves, it would make sense if this were the case - however there was no tangible evidence to prove any of the experiments in the end.
The only references to moonlight I could find was the possibility that like anyone - there are those that are susceptible to types of light affecting their mood. Therefore, whereas one person is delighted in the daytime, and depressed by the moonlight, another person would be just the opposite. Whereas Sunlight promotes serotonin in most people, the lack of it by the moon shouldn't be reason to assume depression / bad connotations.
Really, the only credibility I can lend this theory is that we are not nocturnal creatures, we are emotionally sensitive, and some people might be affected by the moon's light as it may seem foreboding to them. On the long stretch of things, I might go so far as to extend my willingness to accept further investigation to the earth / moon / sun alignment at full and new moons regarding the tidal effect that might cause some sort of mood behaviours related to highly sensitive organs and glands in highly sensitive persons.
My 2 cents anyway. Good fun
