The sky lit up, the night rumbled and the earth shook. Where it was heading and where it landed, nobody knows. But to witness the strange phenomenon residents had to be within a 50km radius of the meteorite's path; and there was no shortage of witnesses in Port Macquarie. Mark Shelton had to pinch himself when he woke up. The Gilmore St resident said the reserve at the back of his place glowed with an intensely bright light for about five seconds. "It was like nothing I've seen before in my life," he told the Port News. "It was so bright I didn't know what it was. I got up walked onto the balcony and 35 seconds later heard distant explosions followed by earth tremors that made the windows rattle. "I was scared of the light because I've never seen anything like it. It was like looking at the sun, but worse." The noise people heard was the sonic boom from the fireball hitting the earth's atmosphere. If parts of the fireball break through the atmosphere, the rock that survives is a meteorite that will land on earth. Astronomers can't tell if this happened on Monday because there have been no reports of people finding the rock. According to Sydney Observatory astronomer Dr Nick Lomb, it's not uncommon for meteorites to reach earth. In June a meteorite shot through the roof of a New Zealand home and in 1999 a Dunbogan home near Port Macquarie was hit. Fifty years ago in Alabama, USA, a woman was hit by a meteorite that came through her bedroom roof while she was sleeping. And, if you're lucky, or unlucky, enough to get in the way of the meteorite, at least the rock will pay for the repairs because the outer atmospheric collectibles are valuable. On the flip-side, a meteorite looks like any other rock and is impossible to distinguish without testing or unless it was seen falling out of the sky. By LAURIE SULLIVAN First there was a growing 'shewwwwwwwwing' sound from the north-west. Almost simultaneously, the fish began boiling on the surface of the water. Then, as if on cue, the lights on the bridge went out just as a fuzzy object the colour of a smoke-filtered sun with a long tail flashed overhead, rocketing out to sea. Port Macquarie man Lloyd Eyles witnessed what he described as 'the spectacle of a lifetime' while fishing from Lake Cathie Bridge at 4am on Monday. The well-known local fishing identity had an armchair view of the meteor which made a noisy pass over the Mid-North Coast. For most people - the light sleepers anyway - it was little more than a window-rattling disruption to their sleep. For Mr Eyles it was a celestial close encounter of the impressive kind. "It all happened very quickly,' he said. "I only just heard the shewwwing sound coming from the direction of Lake Innes when the fish went absolutely beserk, boiling up on the surface of the water. "A split second later the lights on the bridge went out as this orange ball passed overhead. "It almost seemed close enough to touch. It was probably much higher, but it appeared to pass about 20 metres above the trees just south of the bridge. "As it moved away there was this loud rumble - like jets breaking the sound barrier or a convoy of trucks carrying boulders." "It gave me the impression it was losing height as it headed out to sea." The brief blackout of the street lights pitched the bridge into complete darkness, allowing Mr Eyles a clear view of the spectacle. There was no shortage of local people woken by the rumble of the meteor. Some like Gilmore Street resident Mark Shelton were quick enough to observe the bright light that accompanied it. It's not uncommon for meteorites to reach Earth. In 1999 a Dunbogan home was hit. While they are valuable, testing is needed to distinguish them from earthly variety. If Mr Eyles' close encounter left him open-mouthed, it did the same for the fish. "It must have shaken them up," he said. "I caught another four whiting, a bream and a flathead afterwards." ------------------------------------------------------------------------ http://taree.yourguide.com.au/detail.asp?class=news&subclass=local&category=general%20news&story_id=356082&y=2004&m=12 Resident says he knows where it is Manning River Times (Australia) 8 December 2004 AN Old Bar resident has begun a search of property near Coolongolook, so sure is he that he knows where Monday's meteorite fell. Gilbert Babinall believes the main part which fell to earth landed with a definite 'thud' not far from where he was travelling on the Bulahdelah expressway. "I ducked... it was that close," said the Sydney cab driver, who was returning home to Old Bar after finishing his weekend's roster. "It was shortly before 4.15 and I came over the top (of the expressway). I had a bird's eye view of the sky and there was this huge light coming hurtling at me for a few seconds. "It was huge, to the naked eye it looked about football size. I've seen shooting stars but this was huge. It had a big fireball tail. "At first the sky lit up, then there was this huge bang. The thing rocketed up in flames, the whole place lit up like daytime. "Fragments started burning in the sky, like flares. They were all colours... green, blue, red and orange. I thought a plane had blown up in mid-air. "There was a delayed noise, like a sonic boom. One piece, which looked about this big," he said, indicating a grapefruit size, "came down towards me. It looked to be falling slowly when it hit the ground, and I heard a thud. "I had ducked because it was dropping down beside me. I reckon I could pinpoint just about where it fell." Mr Babinall reported what he had seen to police, as he feared the fragment could have caused a bushfire. -------------------------------------------------------------------------- http://taree.yourguide.com.au/detail.asp?class=news&subclass=local&category=general%20news&story_id=356078&y=2004&m=12 As small as a cricket ball Manning River Times (Australia) 8 December 2004 THE meteorite which gave Manning residents an early wake-up call on Monday could have been as small as a cricket ball, according to a Mid North Coast astronomer. Win Howard of the Boambee Observatory, near Coffs Harbour, was asked by the Times for his explanation of the loud explosion which shook the Mid North Coast and rattled homes across the Manning about 4.16am. Although he did not hear the explosion, one of his neighbours heard 'a loud bang' and initial reports indicated it was an earth tremor along the Dividing Range, Mr Howard said yesterday. But as further reports started coming in, it appeared more likely that 'the meteorite theory' was the most possible cause. (Whether it was a meteor, or became a meteorite, is unclear. Meteors are fragments travelling through the sky - they technically become meteorites if they hit the ground.) "The normal cause of such a noise is a meteorite," Mr Howard said, and in most cases they are not very big - probably no bigger than a cricket ball. "But they make a spectacular entrance depending on the angle at which they approach the Earth. With the Earth travelling at a pretty fast rate, if the meteor comes in from the opposite direction and also at a fast rate, it can have spectacular results. It can be a collision of thousands of kilometre an hour, and the resulting noise is like a jet breaking the sound barrier. "If it occurs above your horizon, there will also be a brilliant light, sometimes as bright as a full moon." (This is the light described by Times reader Allen Hannaford in yesterday's edition, after he witnessed the meteor 'explosion' a few minutes before the huge bang woke most residents around 4.16.) If the meteor breaks up as it hits the Earth's atmosphere, it can leave a scattering of light behind it, like a trail, and because of the heat, the lights can be coloured green, red, yellow and orange, Mr Howard said. "If it breaks up, there may be nothing on the ground to show for it. If it remains intact, it may land somewhere. Curiously enough, only the outside gets hot, and given a minute or two, it can be picked up." Mr Howard describes the probable meteor of Monday morning as 'just a little fellow'. "Heaven help us if something bigger strikes," he added. As for the loud bang occurring up to several minutes after Mr Hannaford witnessed the explosion, Mr Howard explained that such occurrences are similar to lightning strikes, whereby it takes about three seconds per kilometre "for the bang to catch up with the flash". He remembers being in his observatory about midnight one night, with his eyes accustomed to the dark "when suddenly the place lit up... you could read a newspaper by the light. "Three seconds later, there was a huge noise, just like a clap of thunder, and the belief is that a meteorite hit somewhere off Solitary Island (near Coffs Harbour." Mr Howard said the 'shooting stars' that anyone can witness, up to many times a night, are only about the size of grains of sand, which vapourise under friction and create a spectacle. Some of the debris flying about comes from disintegrating planets or planetoids. Hundreds of meteorites land somewhere on our planet every day, he added, with estimates being up to 40 tons a day in total. But because 70 per cent of the earth's surface is water, most are never found. "Although it is a relatively common event, many happen during the daytime when the light cannot be seen, and because of the distraction of other noises, they usually go unnoticed."
