Whilst taking my dog for a walk, i first noticed two large circular objects close together between 30-50 miles away. these were nw from my position. at first they were casting a beam downwards and i initially mistook this for two police helicopters with search lights on. the two lights became more distinct and the "beam" disappeared until the main lights divided and went up and then down very very quickly. they then rose up again as if following each other before starting to do circles in opposite directions, so that they were meeting (almost crashing | thought) in the middle before repeating this at least 4 more times. they then appeared to chase each other up, down and around each other until disappearing into thick cloud. it was between 8:30pm and 8:45pm. although this did not happen close to me, my experience has left me shaken and i am now in no doubt that there are others in this universe! i didn't have my phone on me, so was unable to take footage however, my phone is of poor quality anyway.
