There was at least 15 lights approximately a mile apart flying from the west to east. a few broke off towards the north. they were above the stratosphere at first glance they looked like satellites but they kept coming in a line evenly spaced apart. after the ten or so there was one that was heading north. it would flash then disappear for about a minute or so then flash again. the lights started changing direction at the end, instead of following the west/east line they were starting to shoot to the northeast. i am not sure when they first appeared as i was not outside when it turned dark. there was even spacing as they appeared.
