According to Argentinean news, thousands of people spotted a UFO on Sunday in and around the town of Gualeguaychú.
Several Argentinean news outlets reported the sighting, although there is not much detail given. What was seen is most often described as a bright light that slowly moved over the city. According to Argentinian news website Noticias Villaguay, one witness described the light as “a white light, large, and down green.”
Some say the light blinked on and off periodically, and at one point disappeared. This can be seen in at least one of the several videos captured by witnesses and posted to YouTube.
