This comes from a mexican show that hosts Jaime Mausán, a ufo investigator (don’t ask) where he speculates the nature of this thing, he immediately discards the possibility of a balloon, god knows why: http://www.youtube.com/watch?v=MuCaPGMKc_s

He mentions it was recorded in Cuernavaca, Mexico.

Another UFO investigation institution demonstrates it is a balloon indeed http://www.youtube.com/watch?v=pIkGsQF0Joo&feature=related
