A bright light was seen across the sky over California early Tuesday morning, February 14, 2017, and later identified as a Navy missile test. The object appeared in the sky for at least 45 seconds. Many said it changed trajectories.
The event was described as a bright light with a large, glowing tail that slowly moved across the early morning sky.
Navy Strategic Systems Programs spokesman John Daniels said an Ohio-class submarine off the coast of California, south of the Bay Area, launched two Trident II D-5 missiles, one at 03:30 and another at 06:20 local time.
It was the latter one that was seen by many people who shared images and speculated what it might be.
