Didn't see it myself as I'm over in Liverpool but my mate sent me a video on WhatsApp that someone had shared in a Facebook group - said it came from Phoenix. Quality wasn't great but you could make out three distinct points of light holding a tight formation. What got me was they didn't seem to drift at all, just completely stationary for a good while then apparently moved off together.
Wondering if anyone who actually saw it in person could say how high up it looked? Like was it low enough that you could rule out satellites or high altitude aircraft doing something unusual? I do a fair bit of cryptid research so UAP stuff isn't my main area but formation lights that hold position like that are harder to explain away than a lot of what gets posted here. Was the movement at the end slow or did it accelerate quickly? That detail tends to matter with these reports.
