Hi guys Just wanted to pick some brains. I happened to be awake at about half three this a.m. (don't ask!), and, on the offchance, looked out the window. It was fairly cloudy, but there was a whole load of blue-ish light to the north west that I could see in the clear slots behind 'ordinary' clouds. Was this NLC? If so, it was incredibly bright, even through the cloud cover! thanks -PBS-
