A UFO believed to be an "alien megastructure" appeared and vanished over the span of two minutes above the Melbourne sky in Australia.

Cue "The X-Files" theme music. The Australian UFO hunter UFO Lou spotted what seems to be a triangular UFO and uploaded his discovery to YouTube on Nov. 13, 2015, noting that he has "never seen anything like this before."

"Object seems static. Simply appears, lasts a few minutes, then vanishes. Massive in size. Using a 50 mm lens. Orion's belt in frame for scale," UFO Lou continues on his YouTube upload.

Could this be what he thinks it is? Well, it's possible because it seems that the Australian UFO hunter is earnest and critical in his findings.

"I really do try to capture authentic 'unknown' objects. I am my own worst critic before posting. Folks!... I just upload what I record. You judge it for yourself," UFO Lou describes himself on his channel.

He also doesn't want to jump to conclusions without any hard evidence yet, which indicates a meticulous attitude.

"Can't rule out the possibility of some kind of reflection," he notes.

YouTube users were quick to comment and give their support.

"[C]raft showing cloaking technology, most probably interdimensional," user Jeff Patton writes.

By "cloaking," the user is referring to the alleged technology that aliens use to camouflage their spaceships at the touch of a button, where they can observe other living beings unnoticed.

Scott Waring of UFO Sightings Daily scrutinizes UFO Lou's discovery and commends the UFO hunter for his sightings.

"The shape of the UFO here is that of a giant triangle with severed wing edges on its left and right side," Waring writes.

Moving forward, it seems that there has been a steady supply of UFO sightings in Melbourne, as Peter Maxwell Slattery also captured one on two cameras on Oct. 14, 2015, describing it as what seems to look like a kite.
