Strange ring-shaped anomaly appears out of nowhere in sky over Ciénaga, Magdalena, Colombia

On October 4, 2019 an unnatural looking rectangular shape can be seen in the sky over Ciénaga, Magdalena in Colombia when out of nowhere a strange black ring-shaped anomaly appears and slowly moves away from the rectangular shape.


Could it be a cloaked circular UFO coming out of the rectangular shape or is it just a natural sky phenomenon?
