Rio Vista, CA, USA

Sighted on Monday 20. November 2017
Reported on
Shape: Ball of light | Duration: 3.5 hours
Source:

At approximately 11:05pm my wife and I stepped outside for a cigarette. I noticed a strange pulsating white light in the sky. At first I thought it was stationary, until I noticed that it was kind of floating around in a strange pattern. My first thought was that it was a drone but this thing started make very fast side to side motions and it would sort of "drop" in elevation and "jump" back to its original position. The light was also very random. There seemed to be no pattern to the light pulsating from dim to very bright. It was almost like morse code. This lasted for over 3 hours which to my knowledge, there are no drones that can stay airborne for that amount of time and Im not sure theres a drone operator out there that would send it up just to hover around for 3.5 hours. Note: between my wife and neighbors, 5 adults ended up witnessing the same thing. No drugs or alcohol were involved.
