EDIT:Recently , I have been observing the moon and i realised the moon seems to be moving very quickly from one place to another, and back to its initial position in a short cycle(few minutes),the movement seems like it's moving back and forth about some axis at very small radius., I don't think this is due to orbital motion around Earth , conz the movement should be very insignificant given that a complete cycle is a calendar month.
Here is my theory: On the day I observed the moon was quite cloudy , I thought there were many clouds in front of the moon which caused uneven refraction due to uneven cloud layers with uneven thickness passing by, hence the moving line of sight slightly deviates .
However, I realise even I observe the moon directly in clear sky, it seems to move pretty quickly and back to its original position in a short time, why is it like that? Is it due a phenomena so called libration?
PS i'm observing the moon just by naked eye.
