6-7 orange lights at high altitude in formation heading south west over Bangor, Northern IrelandBright point-like Orange coloured lights, (in distinct comparison to the white coloured surrounding stars) flying in formation heading south west. There was no shape to any of the light - too small and too high up. They looked like they were very high up. There was no noise. All the lights were flickering. Gradually each of the points flared up slightly and sputtered out, the leading-most light going out first. The lights kept their formation until they went out. Angular distance between the two extreme-most lights was quite large - at least 10 moon widths. The lights looked very like a formation of very high flying aircraft.My guess is that it was a satellite breaking up, and the orange glows were reflections from the sun that had just recently set.
