darren.. good eyes but there were a few bits of high cloud drifting through, one particularly at the time you mention, which appear reddish/brown due to combination of skyglow and some distant light pollution. no aurora this time but it is not out of the question one day in a movie like this even at this latitude.

Phil, at approx 55 seconds a reddish beam of light flashes accross the milky way it lasts more than a few seconds which I assume would equate to half an hour in real time. cloud? Aurora? artefact?
