Orange/Red lights grouped in formation which faded out. - UK.Fairly bright orange-red lights came across from behind trees on the horizon in a couple of groups. The first set came as three lights, perfectly spaced apart from each other in a perfect line. The end one faded out, then the first, then the middle, within the about 3mins of sighting.The second lot came into sight as a perfect diamond shape facing vertically upwards in the sky. They stayed in formation and just like the fist lot faded out.Finally just one odd followed.They lights were fairly bright, and moved fairly fast through the sky (little wind at the time). (Originally i thought they could have been candle lanterns) but they were very high in the sky also, and surly could not have kept such perfect formation.
