'Fallstreak hole' in Perth sky puzzles locals

Perth skies Tuesday morning
A mysterious cloud caused a stir over Perth this morning. Several PerthNow readers have woken to a sight described as "out of this world" after spotting a puzzling UFO-shaped cloud in the sky.

The unusual cloud formation even had experts baffled, with the Bureau of Meteorology taking some time to investigate what the strange phenomenon may be.

Comment: It seems that if the official hypothesis of fallstreak holes recounted above were true, the phenomena should occur more frequently with our cooling upper atmosphere and heavy air traffic. Besides the hypothesis does not account for the circular shape which seems more like a shock wave from above than ice crystals falling from a planes vapor trail. Consider the recent years exponential growth in incoming fireballs heavily impacting our upper atmosphere, a fact that mainstream science usually shies away from or tries to cover up with 'everything is normal and understood' stories, as demonstrated above. The probability of this phenomena being a product of incoming comet debris is high.

To find meteorites, listen to the legends of Australian aborigines

One of the 4,700-year-old impact craters at Henbury Meteorites Conservation Reserve in Australia.
In the heart of Australia, at a remote site south of Alice Springs, the land is pitted with about a dozen strange depressions. Don't drink the rainwater that pools there, or a fire devil will fill you with iron.

So goes one Aboriginal tale that has been passed down across generations. The site is the Henbury meteorite field, which was created about 4,700 years ago when a large, iron-filled meteorite slammed into Earth's atmosphere and broke apart, scattering fragments. The Aboriginal warning is perhaps one of the clearest examples of an oral tradition that has preserved the memory of an ancient meteorite strike, argues Duane Hamacher at the University of New South Wales in Australia. According to Hamacher, such tales may be vital clues pointing toward future finds.

"These traditions could lead to the discovery of meteorites and impact sites previously unknown to Western science," he writes in a paper that will appear in an upcoming issue of Archaeoastronomy and that was published online August 27.

Most myths and tales are just stories passed down through the ages, altered over time like a vast game of "Telephone." But some are based on actual geological or astronomical events that occurred long ago. The search for the truth behind those stories has inspired a field of science called geomythology.

Meteor over Canada caught on video


An Okanagan farmer who regularly takes photos of the sunrise captured a whole lot more this week when she spotted a meteor in the sky. Janette Casey Ewens, who owns Labyrinth Farms north of Kamloops, was in the barn yard at 6 a.m. on Monday when she saw a "thing" falling from above, she told The Huffington Post B.C.

"I ran back up to the house and grabbed my camera and snapped a few pics then hit the record button," she said in an email. "It happened twice a few minutes apart. The second time it happened faster."

The American Meteor Society received three reports of a fireball being spotted from West Kelowna, Cranbrook, and Three Hills in Alberta. Joanne Rosvick, an astronomer and associate professor at Thompson Rivers University, said it was likely space debris that perhaps came from a satellite, reported CFJC.

Meteor lights up Utah's early morning sky

Rodger Fry had just picked up his morning newspaper, when he looked up at the constellation Orion - and saw something most unexpected. At about 4:32 a.m., the president of the Salt Lake Astronomical Society saw a green fireball soaring through the Thursday morning sky. Several others Fry talked to later saw the same thing.

"There was no sonic boom but it was quite large," said Fry, who lives near 5900 S. 800 West in Murray. "It looked like [the meteor] was ... a little smaller than the sun."

That silence tells experts like Fry that the meteor that lit up Utah's skies was likely far, far away from us. Patrick Wiggins, the NASA/JPL solar system ambassador to Utah, hasn't spoken to anyone who heard any sonic boom associated with the meteor.

Comment: See video footage below. Notice how the fireball just 'goes out' after the first flash. Fascinating!

Thanks to the ubiquitousness of dashboard-mounted video cameras in Russia yet another bright object has been spotted lighting up the sky over Siberia, this time a "meteor-like object" seen on the evening of Saturday, Sept. 27.

The video above, shared today by RT.com, shows the object as it streaked toward the western horizon over the Kemerovo region of Siberia. Even through the glare of streetlights and oncoming car headlights it could easily be seen... as to exactly what it was, that's not yet known.

Meteor strikes may not be random

Scientists have found that meteor impacts are not random events but may occur as Earth passes through streams of meteoroids.
Meteor impacts are far less random than most scientists assumed, according to a new analysis of Earth-strike meteors.

The research, reported on the pre-press astrophysics website ArXiv.org, concluded that meteor impacts are more likely to occur at certain times of the year when Earth's orbit takes us through streams of meteoroids.

The majority of meteors analysed hit the Earth in the second half of the year, say the researchers, brothers Carlos and Raúl de la Fuente Marcos of the Complutense University of Madrid.

"This lack of randomness is induced by planetary perturbations, in particular Jupiter's, and suggests that some of the recent, most powerful Earth impacts may be associated with resonant groups of Near Earth Objects and/or very young meteoroid streams," they report.

Meteoroid streams can be generated by the break-up of an asteroid or comet.

A planet or moon can also affect nearby asteroids and meteors, herding them into loose orbits called 'resonant streams', which can be broken up by big planets such as Jupiter and Saturn.

The study is based on 33 meteor impact events detected between 2000 and 2013 by infrasound acoustic pressure sensors, operated by the Comprehensive Nuclear-Test-Ban Treaty Organization.

The sensors are designed to detect clandestine nuclear tests, but also pick up meteor impacts with an explosive energy in excess of a thousand tonnes of TNT.

Charlotte, N.C. -- Dozens of fireball sightings were reported across the Carolinas and Virginia overnight.

According to the American Meteor Society's website, people in Charlotte, Mint Hill and Lancaster were among those who spotted the streaks in the sky. Reports came in around 11:15 Friday night and 3:15 Saturday morning. Twenty-nine reports were made in total.

One man in Virginia Beach captured the light on camera. Jim Rydel's video doesn't directly capture the meteors but shows the flashes in the sky. Some say it appears like more and more fireballs are passing over us but NBC Charlotte's Brad Panovich says it's likely just social media. People can make reports more easily and more often nowadays.

Brad encourages anyone who saw the fireballs to make their report here.

The American Meteor Society (AMS) says four large, unique fireball events were reported Tuesday night.

AMS stated three of the events all occurred within an hour and a half of each other--- a rare happening. The AMS concluded each event was unique, due to the analysis of time, proximity of witnesses and pointing data gathered. It's likely several were captured by NASA, said AMS.

Locations of the events were reported all the way from Florida to Michigan.

Anyone who witnessed the fireball can report the event to the AMS on their website.

This disintegration of this bright fireball lit up the sky of New Jersey, New York and Pennsylvania on September 2014
If you saw a bright object race across sky around 11 p.m. Sunday, you're not alone.

Social media exploded with reports of a fireball streaking across the sky.

A fireball is another term for a very bright meteor, according to the American Meteor Society (AMS).

"Incredibly bright #meteor even at apparently low altitude just fell over #DC. Wonderful moment!" tweeted photojournalist William B. Plowman from Washington, D.C.

Comment: More footage of same.

Meteor streaks across Vancouver skies

A fireball mesmerized people in parts of B.C., Washington and Oregon on Saturday night.

Jen Pickard was fortunate enough to snap a photo of the tail end of what's believed to be a meteor. She and her friend were paddling in Qualicum Beach on Vancouver Island after watching the sun set, when a "huge ball of fire flew by" at about 8:20 p.m.

"It was yellowish blue and flew in an arc," Pickard wrote in an email to The Huffington Post B.C. She described the 45-second streak like a shooting star but much larger and closer.
