First sighting actually occured on August 4th, at intersection of M-53 & M-59, Shelby Township/Utica, MI. at approx. 9:40pm. Four (4) reddish/orange lights, facing southwest, approx. 80 degrees from horizon, curved pattern to right, steady glow, equally spaced.Second sighting occured at my residence (corner of M-59 & Hayes, Macomb Township)between 9:40pm & 9:45pm. Same reddish/orange lights caught my attention, this time facing northeast, approx. 30 degrees from horizon. Five (5) lights appeared moving slowly westward in an inverted 'S' shaped pattern. Some lights were pulsing bright-then-dim. Within a span of two-to-three minutes the lights all dimmed then disappeared.Both occurances were near Selfridge Air National Guard Base. Perhaps some kind of military activity/training?
