Green light in the sky, the mystery continues

So last night I strolled outside again in the evening whilst doing the laundry and what did I see but the green light again. The light appeared in the same location as the night before and came an went with the more significant cloudcover last night. The odd thing is that when there were bright, low lying clouds the green light wasn't visible, leading me to suppose that either :

  1. whoever is projecting this light turns it off when the clouds come over (this supports by adaptive optics telescope theory)

  2. the light is visible not because it is hitting clouds but because it is lighting up other clouds or dust higher up in the atmosphere

  3. I could see the light because it was behind an inverted mountains of clouds nearer to me than where it was reflecting.

Anyways, here is another picture, even worse than the first.
