Meteor fireball flashes across Finnish skies; more than 200 sightings

An especially bright meteor streaked through the sky at around 8 pm on Friday evening. The Ursa Astronomical Association has logged more than 230 sightings of the southbound fireball.

The phenomenon is known as a bolide, an extremely bright meteor that usually explodes in Earth's atmosphere.

A local Oulu man, Markku Paaso, managed to hastily record the atmospheric ball of light with his car dashboard video camera as the bolide fell in its horizontal trajectory.

"It was like a slow-moving, super-bright shooting star," one Yle reader recounts in their sighting.


Friday's bolide is the second bright aerial anomaly logged in Finland this winter. In November a rare fireball was sighted in Lapland that caused a stir in the skywatching community for its fierce brightness. The undestroyed refuse from that earlier meteorite fell to the Earth in Northern Lapland, where it still remains.

Meteor fireball with sonic boom reported over Townsville, Queensland

Residents of the Australian city of Townsville, Queensland have reported seeing a meteor overnight according to the Daily Telegraph.

One resident Melissa Kruse described a brilliant flash in the sky.
"It was a matter of seconds from first sight to it falling out of sight.

"It was pretty spectacular. There was only one."
Ms Kruse added that it looked similar to the Chelyabinsk meteor which flew over Russia in 2013.

The Townsville phenomenon was witnessed by numerous other people who described seeing a "massive light over The Strand".

The Canberra Times stated that cameras at Mt Stromlo Observatory did capture a somewhat blurry picture of the fragment emitting a bright blue-green light.

It left a blue-green light trail behind it and travelled about 80,000 to 120,000 kilometres per hour, creating a sonic boom that was heard and felt by people below.

Bright meteor fireball explodes over southern Norway

Norwegian meteor fireball on December 18, 2017
On December 18, 2017, at 16:37:07 UT, a bright meteor fireball lit up the southern regions of Norway. The event was registered by cameras of the Norwegian Meteor Network on a partially cloudy sky.

A video of the event was recorded by Tore Myhren from Lillehammer, and shows the fireball through some clouds near the horizon.

"The meteor was of sporadic origin, with a radiant located at R.A. = 331,3°, Dec. = 62,2°," writes Kai Gaarder of the Norwegian Meteor Network, as reported by the International Meteor Organization.

Some eyewitness reports describing the phenomena include:

Ørjan Solheim:
"Saw an insane powerful flash of light in Rosendal. The whole valley and the mountains lighted up. A lot of times stronger than lightning. Lasted longer and was smoother than lightning. Stopped the car and went out, but could hear no sound."

Comet 2

Halley's comet and the calendar

When Europe started carving up the world the acolytes of empire started carving up history to support their beliefs and interests.

By 1850 the acolytes of empire had diced and sliced the Annals of China to create a great and glorious history for Comet Halley all the way back to 11 years before the Christian era.

The valuable details existing in the annals of China, and but recently known in Europe, enable us to trace this famous comet with a high degree of probability to the year 11 before the Christian era, - a most important circumstance, not only as regards the history of this particular comet, but as bearing on the constitution of these bodies in general.

By 1986 the Annals of China [with a little help from the Annals of Babylonia] had provided Comet Halley with a magnificent pedigree stretching all the way back to 240 BC.

Cameras outside a University of Wisconsin-Madison facility captured the moment a meteoroid streaked across the night sky.

The University of Wisconsin-Madison's Cooperative Institute for Meteorological Satellite Studies shared footage from a webcam mounted atop the building that captured the fireball's fall from the sky Monday night.

A sparkling bolide that lit up the sky over Russia's Sochi on Friday, Alexander Ivanov, head of the Kuban University laboratory of astrophysics, told RIA Novosti in an interview.

Internet users speculated over violent clapping sounds supposedly accompanying the fireball. Some cited a hissing sound as an unidentified object flew past the location; others remarked they saw merely a flash of light.

On December 4-17 the Geminid meteor shower was expected to approach Earth, peaking on December 13-15, Ivanov was cited as saying.
"There were some flashes of light in the night sky, as a standard bolide, the size of a soccer ball, entered the atmosphere. Part of it was caught on our cameras. Armavir and Sochi also detailed their observations. This brings us to the conclusion that the object had burnt down about 20 kilometers above Earth."
A video of the phenomena has been uploaded here.

Denver, Colorado residents had an opportunity to witness an astronomical event Thursday night, as a large fireball streaked across the sky above the Mile High City.

A man named Greg Kamer was filming a Christmas light display at the Denver Botanic Gardens when he inched the camera up a little bit and saw something blaze across the sky, KCNC-4 reported.

Researchers identify new mechanism that helps explain why meteors explode in the atmosphere

Photographer Marat Ahmetvaleev was taking panoramic photos of the winter landscape when he captured this beautiful image of the Chelyabinsk meteoroid as it exploded over Russia in 2013.
On February 15, 2013, a near-Earth asteroid with a diameter of 66 feet (20 meters) entered Earth's atmosphere traveling at around 40,000 miles per hour (60,0000 km/h). Within a few seconds, the cosmic projectile detonated 12 miles above the Chelyabinsk region of Russia, releasing as much energy as about 30 Hiroshima atomic bombs. This created a gigantic fireball - known as a superbolide - that caused shock waves to propagate outward for dozens of miles, damaging several thousand buildings and injuring 1,500 people.

Though the progenitor of the explosion had an initial mass of over 10,000 metric tons, only about 0.1 percent of that mass is believed to have reached the ground, indicating that something in the upper atmosphere not only caused the rock to explode, but also caused it to disintegrate much more than expected.

Loud explosion shakes houses as suspected meteorite hits Thunder Bay, Ontario

Crater on Highway 61 in Thunder Bay, Ontario, Canada after possible meteorite hits the ground on December 13, 2017
Object spotted by officers Wednesday night, but now police, investigating expert can't find it

A loud explosion that shook houses in a semi-rural part of Thunder Bay, Ont., Wednesday evening may have been caused by a meteorite that landed on the outskirts of the northwestern Ontario city, according to local police.

Patrol officers were dispatched to the area of Highway 61 and Mount Forest Boulevard Wednesday around 11 p.m., to investigate, police said in a written release.

They were called by area resident Linda Pohole, who lives near the Mount Forest subdivision. She said she heard an explosion.

"I called it in thinking that something happened in Mount Forest, and maybe a house exploded," she said. "It was that loud, and my son said he felt the house vibrate."

Police searched the area and found a large, round hole in the snow on the side of the Highway 61, in the area of Mount Forest Boulevard. There were no footprints or vehicle tire tracks in the vicinity.


Comment: A couple of months ago meteorites hit roofs in South Africa and the US. Mysterious booms are increasing dramatically all over the planet, which may be indicative of space rock fragments exploding in the atmosphere.

Even NASA's own space data supports citizens' recent observations, namely the inconvenient fact that meteor fireballs are increasing dramatically.
