Mysterious fireballs explained

It's highly unlikely any trace will be found of the meteorite that lit =
up
the Maritimes last night, an expert says.

Hundreds of people witnessed huge balls of fire crossing the sky about =
9:30
p.m., flooding RCMP detachments and the Rescue Co-ordination Centre in
Halifax with calls.

What they saw was probably a chunk of rock that was part of an =
asteroid,
says John Rucklidge, geology professor at the University of Toronto and =
an
expert on fireballs and meteorites.

"Eyewitness reports are notoriously unreliable because it always =
appears
that the meteorite crashed just behind the trees on the horizon,'' =
Rucklidge said in an interview with CANOE.

"You need witnesses on both sides of the track to even begin to locate =
it,''
he said. ''Even when it hits the ground, unless it's in a populated =
area, it's virtually impossible to find."

(2) HALIFAX FIREBALL 28 OCTOBER 1999

>From Heather Preston <hlp@alum.mitdot edu>=20

>From the Fireball story by Barry Dorey:
> Astronomer David Lane, a professor at Saint Mary's University,
> said witnesses probably felt the shock wave of explosions when the
> meteor began fragmenting, rather than the rattle of impact.
> But he said a similar show over Montreal two years ago littered
> small fragments east of the city.
> Wednesday's display was not part of a scheduled or expected meteor
> shower, he said.

 The Orionids meteor shower extends from October 15 to 29, with a
maximum occurring around October 21/22. The maximum number of meteors
to expect are around 20 per hour and the meteors are described as
fast.

There is also a new long-period comet discovered by LINEAR which is
expected to possibly yield a meteor shower next week.

Somebody tell the readers?

Clear Skies,
