Were you using a filter on the lens by any chance? Could be a car's rear lights reflecting around the filter/lens etc?

Hmmm, could it be flare then? Any red lights near by? It looks like you used an ultra-wide angle lens, which are usually more notorious for flare...
Definitely Aliens........were you smoking at the time ?
actually that is very possibly the answer (smoking) although I prefer the Aliens idea What was your aperture and exposure duration?
Starbursts from the light sources make me think you were stopped up but quantity of stars suggest otherwise.
Looks like someone's stood just out of frame camera right and motioned their hand just within the comp. Do all the frames feature the same foreign element in the same place?
I guess these two explanations really do explain it dunno...but it looks cool!![]()
