Didn't see it myself (I'm up in Oregon) but my cousin lives just outside Phoenix and she texted me about something weird that night, said it looked like three lights moving in formation then just stopping dead in the sky for like a minute before disappearing. She's not really into this stuff at all so it got my attention more than usual honestly.
Did anyone manage to get footage? And what direction were they moving roughly, was it east to west or more north-south? Trying to work out if this lines up with anything tracked on Flightradar or similar sites that night, though obviously formation lights that just stop aren't going to be commercial flights.
Also curious whether the lights were the same brightness or if one was noticeably brighter than the others. My cousin wasn't super specific in her text, she just said "three weird lights" and left it at that which is frustrating.
