UFO Popocatepetl - December 5, 2013 - 05:44
There have been at least 3 other videos of unknown objects entering the Mt. Popo volcano in the last two years. All were taken from the CENAPRED camera that monitors the volcano's activity.
The one shown below is very recent, taken on the 5th of December, 2013. It shows what seems like a fairly large, white object that enters the screen from the right and moves down into the volcano.
The video has had over 25,000 views with most of the comments being quite positive. We have removed the Spanish narrative, and taken out a good bit of the pixelation.
Note: Popocatepetl is one of Mexico's most active volcanoes. After almost 50 years of dormancy, "Popo" came back to life in 1994 and has since then been producing powerful explosions at irregular intervals.
