Strange light passed overhead silently for seven minutes then disappeared.

It was 7'oclock on a dark December morning, the skies were clear,the moon was crescent shape with one star near it.  I was looking up towards the moon when a light caught my attention hovering silently over head but at a great distance.  I followed the light as it passed overhead with my digital camera, I grabbed a passerby and asked her to take a look at the light to see if she knew what it was, she had no idea what it was.  The entire episode lasted 7 minutes before it just vanished.  It was only when I zoomed in on the light after the picture was taken that i realised that i was looking at more than just a light!  There were several lights that changed formation with no noticable change in colour.  Coincidentally, there were several other sightings over West Cumbria during this same week.
Witness submitted two photos, but they are simply a squiggle of light in one, and a dot of light in the other.  We have requested an accurate date from the witness.  PD
