Dr Andy Tomkins says meteorites can been seen hundreds of kilometres away from ground level.
Dr Andy Tomkins is a Senior Lecturer at the School of Geoscienes at Monash University.

He says there were reported sightings of a loud, white flash at ground level at around 6:30pm on the worldwide meteorites news website.

"It would have been a meteorite coming in somewhere from Mars and Jupiter, they usually come from that sort of orbit, and just coming through our atmosphere really, really fast and burning up as it came through the atmosphere and hopefully landing on the ground."

Dr Tomkins encourages people to check their CTTV cameras from Sunday evening in hope of locating the meteorite.

"We can use that to figure out the direction that the meteorite came from and where it's likely to have ended up on the ground, particularly if there is some sort of time stamp on the video that really helps us nail it down as well."

"We use video from multiple directions from where people have seen it from multiple angles to triangulate down toward the ground position."

He says people who heard a loud bang on Sunday evening would have been within close proximity to its landing.

"Usually it gets brighter the closer you are to it, then a bang, the boom people heard is when you're really close to it, people can usually see a smoke trail if they're fairly close."

Was it a bird or a plane? No, a meteorite strikes Ohio man's car

Massa describes the damage to his car after an impact around 2 a.m. Sunday.
Dayton - A Kettering man believes a meteorite hit his car early Sunday morning. Joe Massa said he was driving home in the center lane on I-75 North when his Buick was struck by something around 2 a.m.

Out of the corner of his eye, he said, "I could see something. It was a light, shadow, a beam of light, small. Within a split second, something hit me, the front of the car was pushed over into the far left lane."

Massa said there was a big flash when it hit.

"It was like a silent pop," Massa said, "then there was pressure in the car. I could feel pressure in my ears, like the air had changed in the car, in a split second."

Massa, who manages restaurants in the Cincinnati area, said he pulled over immediately to see if he hit a deer, a dog, or something else. He found nothing, except the damages to the right-front bumper.

Fireball over Brasilia, Brasil - May 24 2014

And with the camera pointed to just 10 degrees above the horizon, hoping to capture some Meteor Camelopardalis stray, behold, caught a bolide in a unexpected elevation, fighting light pollution to display:

New potentially hazardous asteroid 2014 KP4

The MPEC 2014-K35 issued on May 23, 2014 announced the discovery of a new PHA asteroid officially designated 2014 KP4. This asteroid (~ magnitude 16) was discovered by C. Jacques, E. Pimentel & J. Barros through a 0.20-m f/2.2 Schmidt-Cassegrain + CCD telescope of SONEAR Observatory (MPC code Y00), on images obtained on May 20.2, 2014.

According to the preliminay orbit, 2014 KP4 is an Apollo type asteroid. This class of asteroids are defined by having semi-major axes greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). It is also flagged as a "Potentially Hazardous Asteroid". PHA are asteroids larger than approximately 100m that might have threatening close approaches to the Earth (they can come closer to Earth than 0.05 AU).

2014 KP4 had a close approach with Earth on May 11, 2014 at rougly 26.2 LD (Lunar Distances = ~384,000 kilometers) or 0.0673 AU (1 AU = ~150 million kilometers).

We performed some follow-up measurements of this object on 2014, May 20.6, remotely from the Q62 iTelescope network (Siding Spring) through a 0.50-m f/6.8 astrograph + CCD + focal reducer. Below you can see an animation showing the fast movement (the object was moving at 6.5 "/min) of 2014 KP4 on the the sky on May 20, 2014. Each frame is a single 15-second exposure.

'First time' meteor shower may light up skies over North America this weekend

Will the May Camelopardalids light up the sky or will it get pulled out of Earth's proximity by Jupiter's gravity?

North America is in for a natural light show overhead, as a meteor shower expected over the weekend could turn into a full-on sky storm, affecting countries' entire skylines. Its intensity could even outdo the Perseid meteor shower.

Stargazers are expecting the spectacle to hit late Friday and last into Sunday morning, just as Earth passes through a stream of debris consisting of up to 1,000 pieces of a comet it shed in the 1800s falling all around, every hour, at speeds of 12 miles per second (19.3kps).

The so-called May Camelopardalids will peak at about 2am to 4am on Saturday, eastern US time, according to Bill Cooke of the Meteoroid Environmental Office at NASA's Marshall Space Flight Center. The name comes from the corner of the sky where we'll have to focus our gaze to see the shower's most prominent bits - the Giraffe constellation, right next to the North Star.

1,000 years of Meteors in 30 seconds

* Maps produced using the space agency's Asgard program which tracks an estimated 4,000-5,000 meteoroids a day

* Every day, more than 40 tonnes of meteoroids hit our planet, with larger chunks of comet debris becoming fireballs

* The blue map tracks their position in the skies over our planet with the main showers highlighted in white circles

* A second radar map looks at meteoroid speed. The red regions indicate a speed of 7.5 miles/s (12km/s), the green from 26 miles/s (42km/s) and the blue from 41 miles/s (66km/s)

Every day, more than 40 tonnes of meteoroids hit our atmosphere.

Many are tiny specks of comet dust that crumble harmlessly in Earth's atmosphere, producing a slow drizzle of meteors in the night sky.

Bigger chunks of asteroid and comet debris create dozens of nightly fireballs around the planet - and now, these real-time maps mean you'll never have to miss one again.

Nasa's meteoroid visualisations are produced using the space agency's Asgard software program which tracks an estimated 4,000-5,000 meteoroids a day.

Meteor shoots across Tennessee sky

One of two meteors that lit up the Southern sky Thursday night burned up over Tennessee.

Bill Cooke, head of NASA's Meteoroid Environment Office, said the very bright meteor entered the atmosphere over Columbia, S.C. at 9.38 p.m. The basketball-sized meteor flew northwest at speeds reaching more than 78,000 miles-per-hour, eventually burning 52 miles above Pikeville, Tenn., just north of Chattanooga. In all, the meteor flew 290 miles, which Cooke said is quite rare.

The video below is from Cooke's blog and shows the meteor shooting across the sky.


Comment: This report of a meteor was about 45 min prior to a boom heard over West Virginia on the same night.

Charleston - We've received calls, emails, Facebook messages and tweets from many of you asking about a loud "boom" across our region. Many reports indicate that "boom" caused the land to quake.

We started getting reports of the boom around 10:30 p.m. Thursday.

We've spoken with 911 dispatchers in Lincoln, Logan and Boone Counties. Both said the National Weather Service said they believe a meteorite passed through the area, creating a sonic boom. 13 News has learned that many of you are reporting seeing a bright flash of light across the sky.

We've received calls from Logan, Boone and Raleigh counties and have even heard reports of the "boom" as far away as Kentucky. "We hear your reports," said Chief Meteorologist Spencer Adkins. Our newsroom is checking and we're also looking at things from a weather perspective."

No 911 centers we have reached out to report any emergency explosions of any kind.

New information shows people living in other states also experienced this phenomenon. For more, click here.

Flaming ball falls from sky in Australia and crashes 'like a bomb'

Flaming Object

Flaming object falling from the sky (bottom right of photo) seen looking east from Mount Isa about 6:30pm AEST.
Residents from across central and northern Queensland have reported seeing a huge flaming object fall from the sky.

They say what appeared to be a massive ball with a blue and orange tail hit the ground in the suburb of Kelso in Townsville around 6:30pm (AEST) last night.

Resident Kim Vega was sitting in her backyard at Kelso when she saw the moment of impact.

"It was like an explosion but without a sound," she said.

"You've just seen it was like an atomic bomb effect when it would have hit the ground and all the trees and the skies lit up."

Comment: When it comes to covering up for meteors entering the atmosphere, a falling satellite is always a good explanation. In this case, it might be, but the fact is that we live in a shooting gallery, though our scientists and governments use the media to sooth us that everything is under control, when it is not, and nobody is doing anything about it.
