From approx 8:05 to 8:20 PM MNT time on March 26th, 2020 I witnessed the following event. Phoenix Az. 29 white lights travelling the same speed and trajectory. Western skyline travelling East, Northeast approx 25 to 30 degrees off the western horizon line. No flashing lights or color, no vapor trial no noise. 6 of the 29 lights in very close proximity of each other as if 3 were chasing 3; but at the exact same speed. Each of the 29 lights visible for exact same amount of time: Appeared on the horizon line and lost line of sight within 20 seconds; as if the sun was shining on them, then not. Shortly after event started, all air traffic in western sky stopped.
