I was at home letting the dogs out and as an avid sky watcher i noticed 3 bright lights moving in a triangular formation to my north west. i noticed them for their extreme brightness, almost like super bright led lights, i am familiar with most military and civilian aircraft that fly over here and have never seen anything like this before, the brightness, no sound, it was as if it was a car driving in reverse(the lights) no red or green flashing as a normal aircraft has, just solid bright white lights. when i first saw it it took a second to realize something wasnt right about it, it seemed so fluid and tranquil like it did this everyday. it just flew on a constant straight path at a slow speed, no deviations on its path, totally void of sound until i lost sight of it behind trees. i do have a short video and some pictures if that helps? not sure how to transfer video and pics from my phone.
