Posted by MeteorWayne</DIV> From NASA:<h3>Small Asteroid Predicted to Cause Brilliant Fireball over Northern Sudan </h3>Don Yeomans NASA/JPL Near-Earth Object Program Office October 6, 2008 <img src="http://null/images/2008tc3_t.gif" alt="Orbit Diagram of Asteroid 2008 TC3. Asteroid orbit shown in blue" width="150" align="left" /> A very small, few-meter sized asteroid, designated 2008 TC3, was found Monday morning by the Catalina Sky Survey from their observatory near Tucson Arizona. Preliminary orbital computations by the Minor Planet Center suggested an atmospheric entry of this object within a day of discovery. JPL confirmed that an atmospheric impact will very likely occur during early morning twilight over northern Sudan, north-eastern Africa, at 2:46 UT Tuesday morning. The fireball, which could be brilliant, will travel west to east (from azimuth = 281 degrees) at a relative atmospheric impact velocity of 12.8 km/s and arrive at a very low angle (19 degrees) to the local horizon. It is very unlikely that any sizable fragments will survive passage through the Earth's atmosphere. Objects of this size would be expected to enter the Earth's atmosphere every few months on average but this is the first time such an event has been predicted ahead of time. <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

Interesting side note. In less than one day this asteroid had 541 observations reported to the Minor Planet Center.2007 VK 184, the large asteroid (130m vs 3m for 2008 TC3) with the highest known odds of impacting the earth (not just creating an atmospheric fireball) has a total of 101 observations over a period of 60 days.Emily Lakdawalla reported a  late release by Ron Baalke from JPL's Paul Chodas:<blockquote>Update - 6:45 PM PDT (1 hour prior to atmospheric entry) Since its discovery barely a day ago, 2008 TC3 has been observed extensively by astronomers around the world, and as a result, our orbit predictions have become very precise. We estimate that this object will enter the Earth's atmosphere at around 2:45:28 UTC and reach maximum deceleration around 2:45:54 UTC at an altitude of about 14 km. These times are uncertain by +/- 15 seconds or so. The time at which any fragments might reach the ground depends a great deal on the physical properties of the object, but should be around 2:46:20 UTC +/- 40 seconds.</blockquote> <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

From Spaceweather.com:"The following potentially confirming report comes from Jacob Kuiper, General Aviation meteorologist at the National Weather Service in the Netherlands: "Half an hour before the predicted impact of asteroid 2008 TC3, I informed an official of Air-France-KLM at Amsterdam airport about the possibility that crews of their airliners in the vicinity of impact would have a chance to see a fireball. And it was a success! I have received confirmation that a KLM airliner, roughly 750 nautical miles southwest of the predicted atmospheric impact position, has observed a short flash just before the expected impact time 0246 UTC. Because of the distance it was not a very large phenomenon, but still a confirmation that some bright meteor has been seen in the predicted direction." <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

Emily Lackdawalla of The PLanetary Society has, as usual, done a fine job summarizing the full story from the first images through atmospheric impact. I might copy some excerpts, but would suggest you read the whole thing...http://www.planetary.org/blog/ <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters.

Replying to: <DIV CLASS='Discussion_PostQuote'> Posted by MeteorWayne</DIV> I really think we need a space or moon based early warning outpost.  Perhaps even a few of them!    I do feel good that we found this 2 meter thing, but someday a danger may arrive quicker and could be missed due to ground-weather or many other reasons. Does radar work at distances in space of 100,000 mi or so?  Could relatively small detection outposts be built?   <div class="Discussion_UserSignature"> </div>

Today's APOD is an image of the long lasting train of this event.Explanation: On October 7, the early dawn over northern Sudan revealed this twisted, high altitude trail. Captured in a video frame, the long-lasting persistent train is from the impact of a small asteroid cataloged as 2008 TC3. That event was remarkable because it was the first time an asteroid was detected in space before crashing into planet Earth's atmosphere. In fact, after astronomers discovered 2008 TC3, the time and location of its impact were predicted based on follow-up observations. Later, the impact predictions were confirmed by sensors, including a Meteosat-8 image of a bright flash in the atmosphere. Astronomers are now hoping for more reports of local ground-based observations of what must have been a brilliant meteor streaking through Sudan's night sky. Additional reports could improve the chances of recovering meteorites. http://antwrp.gsfc.nasa.gov/apod/ap081108.html <img src="http://sitelife.space.com/ver1.0/Content/images/store/1/10/b1ac796d-4132-46d4-8ac2-26218a6c6571.Medium.jpg" alt="" /> <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

It would indeed be of immense scientific importance if meteorites from the entry of 2003 TC3 could be recovered.Lets hope that some will be, though I suppose it's a long shot, given the remoteness of that part of Sudan.

While doing some research for a telephone interview about recent fireball activity, I have discovered a POSSIBLE intriguing link between 2008 TC3 (the Sudan asteroid impact) and the Oct 9, 1992 Peekskill meteorite (the one that hit a car).Not only are the dates coincidentally very close (Oct 7 for 2008 TC3), but the orbital elements for the two objects have a lot of similarities. These are also possibly onnected to what is called the HC34 stream which has produced meteorites during the Oct 5-9 time period a few times between 1812 and today.I don't have the math skills, or the required computional resources to investigate this further, so have handed off the idea to someone who does.It should be inetesting to see what turns up.MW <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

NASA Teleconference about Sudan Meteorite

MEDIA ADVISORY : M09-044 NASA Sets Teleconference To Discuss Recovered Meteorites WASHINGTON -- NASA will hold a media teleconference on Wednesday, March 25, at 2 p.m. EDT to reveal science findings from recently discovered meteorites. The meteorites originate from a small asteroid that entered Earth's atmosphere over the Nubian Desert of northern Sudan on Oct. 7, 2008. The discovery presents scientists with an unprecedented opportunity to understand these nomads of the solar system better.

The briefing participants are:

- Peter Jenniskens, meteor astronomer at NASA's Ames Research Center, Moffett Field, Calif., and the SETI Institute in Mountain View, Calif.
- Steve Chesley, scientist in NASA's Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
- Michael Zolensky, cosmic mineralogist at NASA's Johnson Space Center in Houston
- Lucy McFadden, professor of astronomy at the University of Maryland in College Park

Supporting visuals will be available online at the start of the event at:

http://www.nasa.gov/topics/earth/tc3

Audio of the teleconference will be streamed live on NASA's Web site at:

http://www.nasa.gov/newsaudio "

On a personal note, after many years of corresponding with Dr. Jenniskens via e-mail, it will be the first time I hear his voice!

Re: NASA Teleconference about Sudan Meteorite

Does Nasa usually have conferences for recovered Meteorites?

Thanks

Re: NASA Teleconference about Sudan Meteorite

Only one other case that I recall, the Martian meteorite that showed "potential" life structures.
What is unusual about this one to begin with is that it is apparently (I'm assuming here) part of 2008 TC3, which was tracked before it hit the atmosphere and the impact predicted in advance. That means the orbit is known with unprecedented precision for a recovered meteorite. That means we knew exactly where it came from, and possible what other objects it is related to. I recall I speculated on that relation at the time; there is a cluster of meteorite falls around that time of year through recent years. I'll see if I can find some notes I made at the time.

Re: NASA Teleconference about Sudan Meteorite

I found it; I posted this on Dec 11th in the "For You Space Rock Watcher's" thread.

While doing some research for a telephone interview about recent fireball activity, I have discovered a POSSIBLE intriguing link between 2008 TC3 (the Sudan asteroid impact) and the Oct 9, 1992 Peekskill meteorite (the one that hit a car).

Not only are the dates coincidentally very close (Oct 7 for 2008 TC3), but the orbital elements for the two objects have a lot of similarities.

I don't have the math skills, or the required computional resources to investigate this further, so have handed off the idea to someone who does.

It should be inetesting to see what turns up.

IIRC, the person I handed it off to was Dr Jenniskens!

Re: NASA Teleconference about Sudan Meteorite

That is awesome. I am interested to hear what they discuss. I would hope he credits you with the idea if it is related.

Re: NASA Teleconference about Sudan Meteorite

I certainly don't know if that's the case, but should be interesting. I've found an image of one receovered piece, but can't post it here due to the format it's in.

It's also quite likely if there was an association then Peter and Jeremie Vaubaillon, who is the math whiz part of the team had thought of it earlier. In any case, we shall see.
