Watch: Swarm of 'UFOs' Filmed over Volcano

An infrared web cam observing a volcano in Mexico captured remarkable footage of a veritable fleet of glowing objects that have left viewers guessing as to their nature.

The incident, culled from a livestream video of the Popocatepetl volcano, begins at around 25 seconds into the footage when a handful of glowing orbs come into view.

This initial cadre seemingly gives way to dozens more of the anomalous objects which fill the screen as they fly in all directions.

And then, just as quickly as the swarm formed, it dissipates down to one lone glowing orb that eventually flies away.

Observers have offered a variety of explanations for the enigmatic footage, with skeptics suggesting that the 'UFOs' are only insects or dust from the volcano.

And, to their credit, it certainly does appear that whatever was filmed over the volcano seemed less like an organized group of UFOs and more like some form of mother nature.

However, ET enthusiasts argue that the infrared aspect of the video is key, since they believe that people otherwise would not have been able to see the 'craft.'

Perhaps the two camps can split the difference and decide that the orbs were actually just fairies observing the majesty of Mt. Popocatepetl, like the ones allegedly spotted in Wales last week.

The infrared webcam may be akin to a similar tactic for UFO observation that has become increasingly popular over the last few years: night vision goggles.
