What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
4 circular orange lights, spaced out in an imperfect square, about a hand width apart (as seen from ground), travelling from South to North, in formation. Then 2 other orange lights again from SOuth to North about 30 seconds later.
Did the UFO do any
strange things like hover and then zoom off quickly :
Travelling in formation, no sound, then lights dimmed to be unseen.
