Strange cluster of bright white lights over the southwest skyFriday Feb 19, 2016, approx 6:30 PM to 7:00 PM, I was driving from Chandler, Arizona, to our home in Maricopa, Arizona, on Hwy 347. I was heading south. In the South West sky, I saw a group of lights very uniform in the shape of a rectangle. It looked like several lights side by side and about the same amount of lights in several rows below it forming a rectangle. It began with one rectangle and swooped of off to the left and then turned into a second one. Both remained in the sky for a couple of minutes and then the first one faded away. The second one remained for a few minutes and then also faded away. It never dropped as if they were flares. It remained at the same altitude for about 10 minutes or so. It did not move. It seemed way too high in the sky to be flares or balloons. I saw several cars pull over to the side which I presume to watch the same thing.
