It's hard to discern much from the provided images other than the apparent movement should be ignored as it's simply movement of the camera over a
long exposure. You will note the the light in the lower foreground shows identical movement to that of so called UFO above it.
If I had to guess, I'd say it was simply a star or an aircraft. I don't mean to poo poo your pictures but there is no visible shape shifting that I
can see - just a distant light shot over long exposure with a shakey hand.
Perhaps you can answer some questions.
What time of night was it shot?
What direction were you facing?
What city or town do you live in?
Can you provide the EXIF data?
Perhaps then one of our members like
Phage might be able to rule out the star hypothesis at
least. That guys a living planetarium! However, that still leaves us with other prosaic explanations to remove before we can even agree that it may be
a UFO in the classic sense.
The more information you provide, the closer we will get to the truth of the matter - if that's what you desire of course.
