Travelling home from work at just after midnight, i observed lights in the sky off to my right. the lights were observed after leaving the city of bath (united kingdom) i was travelling on the a4 (bristol road) heading towards the village of saltford (united kingdom) riding a 100cc motorcycle, a journey of 4 - 5 miles that would take about 10 minutes to complete. as i continued towards saltford, i was still observing the lights. as i arrived at the saltford, i was able to observe that the object was almost directly above me. i was able to observe that the object was made of 4 lights, 3 outer and 1 inner, the three outer lights were white in colour, continuous and formed a triangular shape, the inner light was central to the other 3, flashing at regular intervals and of a deep red colour (almost as deep as fresh blood colour). the object travelled from my right to left in a direction roughly from the north to south at a speed i estimate no faster than 10 - 20mph. there was no discernable noise from the object which i estimate was no higher than 500 feet above my position at the closest. i continued my journey and had no further sighting of the object.
