Start here if you are new to the case: what happened, why people still care, and what the archive currently thinks.
What happened?
On March 13, 1997, thousands of Arizona residents reported unusual lights crossing the night sky. The case is best understood as two overlapping episodes: an earlier wave of witnesses describing a large silent V-shaped formation moving across the state, and a later widely filmed row of bright lights near Phoenix that officials and skeptics associate with military flares over the Barry Goldwater Range.
What the file contains
The current file compares 19 source reports across 7 evidence blocks and 2 explanation blocks.
Current read
The Phoenix Lights are real as a mass-witness public event. The later filmed lights are strongly explainable as flares, while the earlier moving formation reports remain less cleanly resolved and should be treated separately.

Case Verdict
Best current interpretation
Strongly supported
YouTube provides source material for Phoenix Lights.
Likely explained
The strongest debunk targets the later row of lights, which many analysts connect to military illumination flares dropped over a range southwest of Phoenix.
Still unresolved
Which witness reports belong to the early moving formation and which belong to the later light row?
The Phoenix Lights are real as a mass-witness public event. The later filmed lights are strongly explainable as flares, while the earlier moving formation reports remain less cleanly resolved and should be treated separately.
