The Ashtar Galactic Command is an extraterrestrial organization whose existence and purpose is asserted by contactees, New Age believers and channellers, including American Ufologist George Van Tassel. The Command consists of several named beings with distinctly defined roles.
Vrillon, a purported representative of the Ashtar Galactic Command, was the name used by an unidentified voice who broadcast on the Hannington transmitter of the Independent Broadcasting Authority in the United Kingdom for six minutes at 5:10 PM on Saturday November 26, 1977.
The voice, which was disguised and accompanied by a deep buzzing, broke into the broadcast of the local ITV station Southern Television, over-riding the audio signal of the early-evening news from ITN to warn viewers of "the destiny of your race" and "so that you may communicate to your fellow beings the course you must take to avoid a disaster which threatens your world and the beings on other worlds around you".
