After putting away my yard tools i decided to sit out on the patio and enjoy a warm summer evening listening to the radio and looking at the stars. this is something that i do quite regularly in all seasons. as soon as i sat down and looked up i saw what i thought was a passing satellite at least a magnitude of -2 maybe brighter. then i saw another and another and realized there were no less than 15 of these objects. i was facing east, it was cloudy to the north, but clear to the south where as far as i could see these objects were passing over. they were spaced well apart. i can not say if they were evenly apart or in formation but all appeared to be moving at the same speed. i live just ten miles south of detroit so there is much light pollution. i tried to get a video and photo but my phone isn't good enough to get anything clear. i did however open my heavens above app and took a screen shot that showed seven unknown satellites on the screen. i ran inside to get my wife and daughter who came out and also witnessed about ten more still passing over.
