A SPACE rock reportedly caused a sonic boom as it crashed into earth's atmosphere over Japan, the country's media reported.
Videos of the extraterrestrial object, which happened to descend on World UFO Day, show Tokyo skies lit up with green and purple hues.
The mesmerizing event happened at 2.32am local time on July 2, with one local saying they thought "a person living [in the condo] above knocked down a shelf", the Japan Times reported.
Fujii Daichi, a curator who specializes in astronomy at a science museum in Hiratsuka City, said the fireball looked much brighter than the full moon. "The explosive sound is probably caused by shockwaves," he told NHK. "It is very rare for the sound of a fireball to be registered."
The IMO reported the meteoroid was visible from a large part of Japan's Kanto region, the area on Honshu island that encompasses Tokyo among other cities.
"We were able to calculate a source energy of the entering asteroid of about (165 tons or 150 metric tonnes) of TNT," an IMO post read.
A fireball is a meteor brighter than the planet Venus, according to the IMO.
The fireball was also spotted from the Akeno Observatory, Tokyo Institute of Technology.
By measuring the object through infrasound, the IMO calculated the object would be around 1.6 meters in diameter with a mass of around 1.6 tons.
By coincidence, July 2 was also World UFO Day.
In honor, Google Maps created an online map to pinpoint locations of mysterious UFO sightings.
The fun tool, created on Google Maps, pinpoints reported encounters with aliens across the globe using data spanning several decades.
The digital map was uploaded to GoogleMyMaps, which lets users put together custom maps and share them on the web.
Crafted by an anonymous conspiracy nut, it shows dozens of UFO reports in regions from Kazakhstan to Australia.
Clicking on a location brings up more information about it, such as the date and nature of the reported sighting.
The tool includes UK and US UFO "sightings", such as a 1974 incident involving hikers in Llandrillo, Wales.
Described as a bang and a flash of white light, the incident, dubbed the "Welsh Roswell", was dismissed as an earthquake and a meteor combining.
The map also describes a 1995 UFO sighting above Nevada.
"In October 1995 a man witnessed what looked like a giant fireball in the night sky," the map says.
"He reported that it was mostly red in colour with a greenish centre. The object reportedly gave off a sort of energy that the witness felt."
Thousands of alleged UFO sightings have been reported since the mid-20th century, though none are backed by irrefutable proof.
And while scientists have widely denounced the observations as nonsense, reports continue to pour in.
A second sightings map, crafted by US conspiracy group The Crypto Crew, marks Bigfoot, UFO and other "odd sightings".
"The Pins marking the locations may not be spot on but are very close in most cases, but some are spot on," the map's description reads.
The map has dozens of alleged encounters to scan through, including famous sightings in California and New York State.
