Victoria UFO wave, Entre Ríos
In 1991 residents of Victoria, a river town on the Paraná delta, reported so many lights rising from the river and islands that local researchers spoke of an 'invasion'; the town has billed itself a UFO capital ever since.

The account
The sisters Pérez Simondini of the group Visión OVNI documented the wave and later opened a UFO museum in Victoria, with photos and home videos of lights emerging from the Paraná at night. Further waves were reported in 1998, in 2006, in 2010 (when a local researcher said there had never been so many sightings in one year) and in 2021, when lights were filmed over the Laguna del Pescado.
The sceptical view
The delta has heavy river traffic, fishing boats, distant city lights and frequent temperature inversions that distort lights over water. Most of the material comes from local enthusiasts rather than independent study.
