Weather Eye: Nasa spots asteroid before annihilation


October 8, 2008


In the early hours of yesterday morning a fireball exploded with the equivalent of a thousand tonnes of TNT over northern Sudan. The light was so intense that it lit up the sky like a full moon and an airliner 1,400km (870 miles) away reported seeing the bright flash.

The explosion was caused by an asteroid the size of a boulder roughly three metres (10ft) across.

Please visit the link provided for the complete story.

So, next time someone blows up a suitcase nuke, they can say it was an asteroid...

Slow and graceful yeah? Those can be real beauties, and it certainly sounds like the one you saw was! It was probably a Daconid or a Taurid meteor. Both showers are active at the moment, and can produce flare like meteors. Pure white also fits them well.

Boy oh boy it was something. I was just wondering if I heard the boom from it a minute later or two later. I thought it was a door slamming shut or something dropping (you know living in the city noise right?) But it had a a booming echo kinda. I dont know if it was from the meteor, though I doubt it as it was about a minute or two later.That video was close to what I saw. Though without the tail completely, but freaking bright!

I'm surprised there was no trail whatsoever. Bright meteors usually leave very distinct (and often long lasting) trails, although this is not always the case.

The boom you heard could well be connected to the fireball. The timing is about right, and your description of the brightness is more than enough for booms to be associated with it. Hearing a boom potentially means that this meteor could have dropped a meteorite somewhere. There is also a possibility that what you saw was space-junk re-entering.

I'd strongly encourage you to submit a fireball report with the link I provided. There may well be other witnesses to this event, and your report could help coordinate a search for any rocks that may have made it to the ground.

Good work hanging around long enough after to hear the boom by the way. Not many people get to hear sonic booms from meteors!

I am pretty sure that was the sound. I maybe mistaken, but nontheless I did see it and possible heard the booming sound. Man I love this stuff. Reminds me of the time when a meteor blew up over Chicago a few years ago, showerin the area with debris. My dad saw the flash, but thought it ws lightning (from a cloudless sky lol). Not until the morning did we hear about what happened.

And yes I did send in the report too. I wonder if I will get a reply? Do they send a reply or something?

From what I understand, the sound is something like thunder in the distance. Sometimes more than one boom is heard.

I remember the Chicago meteor.You guys get all the luck over there in the US. It seems to be a bolide magnet lol! Incidentally, lightning has been know to strike from a cloudless sky - it can strike up to 6 miles (or is it 9? better stay 10 just in case lol) away from a thunder cloud.

You might get a reply. It depends. If only one person sees a fireball it makes it impossible to triangulate a rough trajectory and work out a possible meteorite landing site, but if they can get at least 2 or 3 reliable reports from whitenesses spread out over a wide area, and either side of the of the path of the fireball, then they might get in touch with you to try to help narrow the trajectory down.

I've not heard any other reports of the same event yet, but it's still early days. If I do come across any news I ' ll post it on your thread.

Ok, thats cool! Thanks! I found out one of my friends also saw it Thursday too. I'll be sure to tell him to report it to them too.

New Scientist - interview with Peter Jenniskens

What did you find when you analyzed the meteorites?

[The meteorites belong to a known type, but they are] different from the ones that have been recovered before, in the sense that [they're] very fragile and very dark, because there's lots of carbon. It's material that was heated so much that part of the rock became fluid but not the whole rock. It illustrates what happens in a certain phase of planet evolution before things get all molten (see Magma oceans sloshed across early asteroids).

We can now say with certainty that this dark variety corresponds to F-class asteroids. There are many ideas about how these rocks formed, so we're hoping that this meteorite will be able to differentiate between them. That's sort of a next step in the study.

Although not a new class of asteroidal material, this is a unique composition which has not been found before. This particular asteroid appears to be a mixture of two different types of asteroid that collided and combined together to form a type of material which belongs to a group that scientists call Ureilites.

The ureilites are named for Novo Urei, a rural village in the Mordova Republic, Russia, where several meteorites fell in late 1886. It has been reported that one stone was soon recovered by local peasants - but not to preserve it for science. On the contrary, the stone was immediately broken apart and eaten! The report does not reveal the reason for this odd behaviour - maybe they ate it because the freshly fallen meteorite smelled good, or perhaps because it had the typical shape of a loaf of bread, which a ureilite often resembles. However, not all of the stones were eaten, and Novo Urei became the type specimen of one of the best-represented achondrite groups in our collections. The ureilite group comprises about 60 members, again, excluding all probable pairings from the hot deserts of Africa and the ice fields of Antarctica.


These new samples together with the data collected should keep the researchers busy for a while.
