Yea,
to produce that big flash would only require a suitcase sized rock...
A house travelling at 40,000/kph would make a really BIG explosion....
Anybody here see it?
(i need photos ;) )

"However we didn't find anything - there was no bloody great rock sitting in the middle of the highway, anyway".
No wonder the Auzzie cops didn't find anything. Meteroites generally disintegrate when they make explosions :lol:

Hum,
Generally...
But a 1.3kg meteorite fell through the roof of Brenda Archer's house in suburban Auckland, NZ, recently.
The meteorite itself could have been basketball-sized when it impacted Earth's atmosphere at 15km a second. By the time it hit the house, its velocity had probably slowed to 100-200m a second.
“There was just a huge explosion and we looked around and there was just dust everywhere."

Overseas dealers were expected to offer the Archers cash for the rock, the rock could be worth more than $10,000 - coming through the roof added significantly to its value.
:-)
(er, so it`s worth a look)

Ah maybe, though slamming through a roof is a bit like a break-fall, compared to slamming into around several miles thick of crust/ground. If it made an explosion like the pic shown in the news page, then its likley to disintegrate.

Seems to be a bit of a spate of these. (Or is it just a passing fad with respect to news coverage?)

Hum,
They`re probably unrelated, but the June Bootids are due soon (Active : June 26-July 2), and recent studies indicate the Earth may encounter potentially substantial June Bootid rates again in 2004 on June 27, around 1h UT.
They should be a pretty nice sight on a warm clear night....
They come from chips/dust off the Comet 7P/Pons-Winnecke, but i suppose that occasionally really big bits fall off...
So stay frosty over the next week!

As an update to this story it seems as if the New Zealand couple (retired) have rejected a hefty offer($50,000 NZ /USD32,000) for the meteorite that hit their house and have taken it off the market.
The`ve decided the rock should be available for public display. Next week, it begins a two-month run in the Unseen Worlds exhibit (er, worth looking out for) at the Auckland Museum, and it is also scheduled for a space exhibition later this year.

Hum,
And strangly
another huge meteor has been seen
in the skies over central Victoria.
There have been reports of a big red and blue light streaking over the Castlemaine (XXXX) area just after 1:00am AEST 29th.
A Policewoman, Senior Constable Sharon McEachern, on patrol duty saw the light in the sky; saying it was a spectacular sight that lasted about 15 seconds.
"A bright blue light going across the sky...not coming
straight down and it just had a large blue tail and a bright
red ball and then as it went across it just exploded into
pieces, so I'm not sure whether it was a comet, or a
meteor, or what it was,"
Remember Grovers Mill, New Jersey?
