What is that strange picture artefact just left of centre and dead

just below dead centre, and the other a bit longer to the right of it.

If there were only two, I'd put it down to some weird lens reflection,
but the third one kills even that unlikely suggestion.


Its just falling snow leaving trails due to a fairly long exposure.
