'Big, bright' meteor seen over Tasmania

Image
A meteor sighting over Launceston this morning has prompted a reminder that cold, clear winter conditions provide a perfect platform for sightings. As northern Tasmania shivers through sub-zero overnight temperatures, the clear skies helped the region's early risers spot a rare meteor display.

Residents near Launceston reported seeing a large, bright meteor travelling through the sky just before 5:00am. Lesley from Gravelly Beach told ABC Northern Tasmania she witnessed the bright display as she drove to Launceston's airport.

"It was so big and so close and I thought 'gee, this is going to land in someone's backyard'," she said.

"I've never seen anything as big as what this was before, and so bright - in the tail there were a couple of very bright spots."

Local astronomer Martin George said meteors occurred more often than people thought, but seeing a bright one was rare.

"The longer you spend looking at the night sky, the more likely you are to see meteors," he said.

"Typically you'll see about five or six every hour, but brighter meteors are few and far between."

He said with colder nights often leading to clearer skies, now was the best time to be on the lookout.

"We also have longer nights in the winter, which means there is plenty more opportunity to go out stargazing or meteor-gazing and, of course as always, you do see much more if you're away from those nasty city lights."

Wollongong astronomer David Finlay says meteorites like this could have fallen in areas in north western Sydney following sightings of a fireball over the Illawarra and Sydney on Sunday evening.
Reports of a bright, fragmenting fireball visible from the Illawarra and Sydney on Sunday evening has Wollongong astronomy enthusiast David Finlay on the hunt to find out what happened after it disappeared, with the chance people could have a meteorite on their property.

If Sunday evening's striking pink sunset across the Illawarra wasn't enough, about an hour later there was another exciting event in the sky.

Wollongong astronomy enthusiast David Finlay says he's getting reports from people in Wollongong and Sydney who saw a bright meteor with a glowing orange head blazing through the sky, leaving a green tail behind.

"I've been told just before it got to the horizon, it exploded and fragmented," Mr Finlay says.

"That description of it exploding and breaking up is a key indicator that the object that created this meteor may have been big enough to leave meteorites on the ground.

"We can narrow down the search area and maybe notify people that live in the area there may be meteorites on the ground from this event."

David runs the Facebook page Australian Meteor Reports, where people can share their sightings.

Sunday evening's event prompted several people to jump on the page and report what they saw.

New asteroid discovered - Amor Asteroid (2015 KQ154)

The MPEC 2015-K126 issued on May 28, 2015 announced the discovery of a new Amor-type asteroid officially designated 2015 KQ154. This asteroid (~ magnitude 16) was discovered by C. Jacques, E. Pimentel & J. Barros through a 0.28-m f/2.2 astrograph + CCD telescope of SONEAR Observatory (MPC code Y00), on images obtained on May 25.1, 2015.

According to the preliminay orbit, 2015 KQ154 is an Amor type asteroid. Amor asteroids are a group of Near-Earth objects with orbits similar to that of 1221 Amor (1.017 AU < q < 1.3 AU). They approach the orbit of Earth from beyond, but do not cross it. Most Amors do cross the orbit of Mars.

We performed some follow-up measurements of this object on 2015, May 28.4, remotely from the U69 MPC code (iTelescope network - Auberry California) through a 0.61-m f/6.5 astrograph + CCD. Here you can see an animation showing the fast movement of 2015 KQ154 on the the sky on May 28, 2015 (it was moving at 8.35 "/min). Each frame is a single 10-second exposure (East is up, North is to the right).

Congrats to SONEAR team for the discovery of 2015 KQ154, that is the thirteenth Near Earth Object discovered by their survey.

Mysterious bangs heard in Auckland

Mystery Boom

What was the unexplained bang heard in Auckland on Saturday night?
A mysterious loud explosion has stumped residents of Auckland's central suburbs as to what it could be.

The banging was reportedly heard on Saturday around 11.30pm.

Police say they had no reports of anything that may have caused such an explosion, other than fireworks being let off.

The noise was heard in the Mt Albert, Mt Roskill and Three Kings area - as well as far away as Waterview to the west and Papakura to the south.

Resident Ash Ball said there was a massive explosion which woke up the neighbourhood. "It shook our house and woke us up with a hell of a fright."

But some residents are convinced something more untoward is going on.

One person tweeted that it sounded like a bomb exploding while another emailed to Stuff declaring it to have been a sonic boom.

In June last year, a series of mysterious "explosions" were reported across west and north Auckland leaving police mystified then as well.

Those explosions turned out to be Defence Force training exercises at the Kaipara Bomb Range.

'Flying rocks from a quarry' (right!) damage homes, businesses in Virginia

Image
Bob Ryan was driving to get a cup of coffee in Sterling, Va., on Thursday morning when he saw rocks the size of baseballs shower out of the sky.

"They hit, and then smaller ones hit in succession like, 'boom, boom, boom,'" Ryan said.

At first, Ryan thought maybe kids hiding in a treeline were pelting cars. But he noticed that the rocks appeared to have rained down from the clouds, as if they were meteors.

Laura Rinhart, a Loudoun County firefighter, said that the rocks likely were not from outer space and had instead come flying from a nearby rock quarry. Rinehart said that some rocks struck a home on Old Ox road and debris also hit the pavement near Oakgrove Rd.

A person who answered the phone at Loudoun Quarries on Thursday said he was not sure if the rocks came from their quarry, the only quarry in the area.

Some residents in the area heard a boom at around 10:30 a.m. that they thought sounded like thunder. Ryan said that stones then blasted car windows and damaged vehicles in a shopping center parking lot. He said he picked up some of the rocks and noticed that they had a burnt smell.

"One rock double the size of a softball was sitting on the sidewalk in front of a beauty salon," Ryan said. "If it had gone through there would have been lots of casualties."


Comment: In relation to the rock quarry, Old Ox Road is 3-5 miles West of the quarry, other locations reported are 2 miles or so East of the rock quarry. Why not rocks North, South, East and West? There isn't enough information to know for sure, but this seems fishy!


Comment: This story is a bit farfetched and reads like damage control. Here's another piece from USA Today with video of a rock coming from the sky. Would a controlled blast also create a burnt smell on the rocks?
The smell that is being given off by this meteorite is hard to describe. When I first smelt it, I tried to think of the proper words to describe the odor. I tried to think of things that had a similar smell:

"like hot metal, or like a cast-iron skillet that has over-heated, or like the metal filaments when you first turn on an electric heater.
Also, a lot like when you make sparks by striking two flint-rocks against each other.
Maybe a little like ozone, but with a more smoky, sulfurous aroma."

That's when the phrase "burnt gunpowder" came into my mind.

And...
Chelyabinsk. Meteor Smells

A group of four observers of the Leonid meteor shower of 1833 reported a peculiar odour, "like sulphur or onions."

It was thought that "This apparent transmission of smells at the speed of light could be explained if they were due to nitrous oxide or ozone produced by an electric discharge." (Ozone [O3] a gas. From the Greek, ozein, for smell). Observers of the Texas fireball of 1 October 1917 also reported the odour of sulphur and burning powder as it passed.

A possible explanation is suggested by the following Chelyabinsk observer reports.

Field survey reports of smells were concentrated in the area surrounding the fireball trajectory. After an initial strong burst, the smells continued for a few hours. The eastern edge of this area coincides with the eastern edge of the glass damaged area. Arkhangel'skoe is the most western village where smells were reported. It is situated near the western edge of the glass damaged area. Fourteen villages reported similar smells, with nearly all described as a sulphur smell, a burning smell, or a smell similar to that of gunpowder.

These smells may have originated from the decomposition of Troilite (FeS), an iron sulphide mineral named after Domenico Troili, who first noted it in a meteorite that fell at Albareto, Modena, Italy in 1766. Troilite is one of the main components of the Chelyabinsk meteorite. Some burning smells may also have been caused locally when the shockwave dispersed soot from flues and stoves.

Respondents in Emanzhelinka, immediately under the fireball trajectory, also reported an ozone smell, similar to the smell after a thunderstorm. Ozone, with nitrogen oxides as by products, may have been produced in the immediate surroundings of the fireball by Ultra-Violet (UV-B λ= 290-320 nm wavelength) radiation from the meteor. This reinforces reports about sunburn caused by UV radiation from the fireball.

It's more likely space rocks coming into our atmosphere and the government owned media does not want the people to know they are about to be bombarded back to the Stone Age. What slimeballs.

Meteor blamed for loud boom over New Zealand

Fireball Over Omanawa

A picture of two near earth meteors taken near Omanawa this week is being offered as an explanation for mysterious bangs heard in the sky over the lower Kaimai area.

Omanawa resident and EOL CEO Terry Coles heard what sounded like two large explosions last Saturday night. He wondered at the time if they were sonic booms from a meteor.

His suspicions were confirmed on Tuesday when he set up a camera on the balcony to take continuous exposures for a timelapse video he's working on about the night sky over the Kaimais.

"I left the camera running as I needed several thousand consecutive images and went inside where it was warm," says Terry.

"Just after 11pm I heard three more explosions in quick succession, louder this time as if they were close by."

Suspecting he had missed something special he sifted through hundreds of images from Tuesday night and found something in just one frame.

Meteorite captured on camera by Slovakian observatory in the Canaries
A spectacular image was captured on camera by the AMOS project near Los Cristianos in Tenerife at 23.17 on Tuesday when a meteor illuminated the sky as it hurtled towards Earth.

The meteor, which was first spotted when it was still 83 kilometres away from the planet, disintegrated 25.2 kilometres from the Earth's surface, and was snapped by the cameras of the AMOS project in the observatory of the Instituto de Astrofísica de Canarias Teide y Roque de los Muchachos.

The AMOS (All-Sky Meteor Orbit System) project has been up and running for only two months, and every night scans the sky in search of meteors using two detectors located 140 kilometres apart in Tenerife and La Palma. These devices can calculate the exact orbits and trajectories of the bodies they detect.

The technology was developed by the Astronomical and Geophysical Observatory of the Faculty of Mathematics, Physics and Informatics at the Comenius University in Slovakia, and won a gold medal at the INVENTO 2013 exhibition. Its intended use is for improving meteor and meteorite detection and prediction systems, and in future it is planned to install similar equipment in Chile in order to allow the southern skies to be monitored as well.

Aboriginal legends reveal ancient secrets to science

Meteor streaks across the sky against a field of star.
Scientists are beginning to tap into a wellspring of knowledge buried in the ancient stories of Australia's Aboriginal peoples. But the loss of indigenous languages could mean it is too late to learn from them.

The Luritja people, native to the remote deserts of central Australia, once told stories about a fire devil coming down from the Sun, crashing into Earth and killing everything in the vicinity.

The local people feared if they strayed too close to this land they might reignite some otherworldly creature.

The legend describes the crash landing of a meteor in Australia's Central Desert about 4,700 years ago, says University of New South Wales (UNSW) astrophysicist Duane Hamacher.

It would have been a dramatic and fiery event, with the meteor blazing across the sky. As it broke apart, large fragments of metal-rich rock would have crashed to Earth with explosive force, creating a dozen giant craters.

The Northern Territory site, which was discovered in the 1930s by white prospectors with the help of Luritja guides, is today known as the Henbury Meteorites Conservation Reserve.
