[meteorite-list] NEW Lunar - NWA 4884
Dear List Members, It is my pleasure to announce a NEW and unpaired lunar meteorite, NWA 4884. I've waited over a year and a half to announce this little beauty. It is classified as a Mingled Basalt-rich Breccia 'officially' accepted by the NomComm. NWA 4884 is a gorgeous new lunar meteorite found in the Sahara Desert in early 2007. It consists of a single 42-gram, partially crusted stone and is not paired to any other lunar meteorites, but is quite similar to Antarctic meteorite QUE 94281, and both are mingled mare plus highlands breccias. NWA 4884 has large anorthositic clasts and abundant metal, most likely from ancient impactors that pummeled the lunar surface.

[meteorite-list] 2008 TC3: ! in 5 hours a few meter meteoroid will strike the Earth over Sudan !
http://www.spaceweather.com/ Hello meteorite friends, it will be very spectacular in some few hours. I hope NASA has already sent some measuring aeroplanes and will watch with satellites. Ron Baalke, can we organize that quickly ? Did anybody informed the military in Sudan ? A year ago, looking at the quantity of the quick discovering of some few meter meteoroids, I asked the list, when we can expect a predicted meteorite fall. I asked several asteroid hunters, but they had no idea to estimate that. I guessed less then 20 years, but I had no idea that it will be soon ! Who booked already a ticket to Sudan ?;-) ASTEROID 2008 TC3: A small, newly-discovered asteroid named 2008 TC3 is approaching Earth and chances are good that it will hit. Steve Chesley of JPL estimates that atmospheric entry will occur on Oct 7th at 0246 UTC over northern Sudan [ref]. Measuring only a few meters across, the space rock poses no threat to the ground, but it should create a spectacular fireball, releasing about a kiloton of energy as it disintegrates and explodes in the atmosphere. Stay tuned for updates. [ephemeris] [3D orbit] With best wishes, especially for those who are able to look at the show !

Re: [meteorite-list] Fw: Bolide to enter over northern Sudan in lessthan 8 hours
Hi Mike: There is no way that you would have known that this was going to happen (unless you are good at reading tea leaves). If you look at the observations, the first observation was a little before midnight last night Tucson time. It turns out I was up there with a group of Girl Scout leaders at the other telescope on the mountain, but we left a few hours before the discovery! I am a little surprised that they know so accurately where it will enter the atmosphere, given only one night's observations.

[meteorite-list] Small Asteroid Predicted to Cause Brilliant Fireball over Northern Sudan (2008 TC3)
http://neo.jpl.nasa.gov/news/news159.html Small Asteroid Predicted to Cause Brilliant Fireball over Northern Sudan Don Yeomans NASA/JPL Near-Earth Object Program Office October 6, 2008 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.

[meteorite-list] Space Rock Found on Collision Course With Earth (Asteroid 2008 TC3)
http://space.newscientist.com/article/dn14880-space-rock-found-on-collision-course-with-earth.html Space rock found on collision course with Earth Maggie McKee New Scientist 06 October 2008 For the first time, astronomers have found an object on a certain collision course with Earth. Fortunately, it is so small it is not expected to cause any damage, burning up in the atmosphere somewhere above northern Sudan in the wee hours of Tuesday morning. It may, however, produce a brilliant 'shooting star'. The space rock, dubbed 2008 TC3, was first spotted on Monday in a survey by the Mt Lemmon Observatory near Tucson, Arizona. Its brightness suggests it is no more than about 5 metres across - so small it will likely be destroyed in the atmosphere, says Andrea Milani Comparetti of the University of Pisa in Italy. Rocks of such size are thought to hit the atmosphere every few months, says Steve Chesley, an astronomer at NASA's Jet Propulsion Laboratory. The event is not unusual - what is unique is that it's been predicted beforehand, Milani told New Scientist. This is the first time we see something arriving, compute that it's going to impact, and announce it is going to impact before it happens. The rock is due to hit the atmosphere above northern Sudan on Tuesday at 0246 GMT. It will be travelling from west to east, and may be visible from a few hundred kilometres away. Long trail The meteor it produces is likely to be spectacular. The rock will release about 1 kiloton of energy in the atmosphere - the equivalent of a low-energy nuclear bomb, says Milani. But it's not clear whether it will do so all at once or over a longer period, perhaps lasting a minute or so. It will hit the atmosphere at an angle of 20°, so it will make a long trail in the atmosphere, says Milani. But we cannot honestly predict how long it will be. [The rock] might end up quite far - above the Red Sea or Saudi Arabia - or it might explode and disappear sooner. If it disintegrates all at once, it would produce a bright flash of light and a loud sonic boom, says Chesley. This space rock is so small it is unlikely to cause any damage. The only concern is that [the explosions] might be interpreted as something else, that is man-made explosions. Thus in this case, the earlier the public worldwide is aware that this is a natural phenomenon, which involves no risk, the better, Milani's team wrote on a popular astronomy listserv. Impact probability The object's discovery is a reminder that larger and potentially more dangerous rocks might also be on a collision course with Earth. Milani and Chesley are members of the only two groups in the world that calculate the probability that a given space rock will hit the Earth. They both say that they are delighted at how quickly this meteorite was determined to be on a collision course with Earth - since it was only discovered at about 0630 GMT on Monday. For us, [we feel] satisfaction because our computation worked and because this kind of accident - which is without any risk that anybody [would be] hurt - will make people more aware of the fact that something has to be done about asteroids in case a bigger one arrives, Milani told New Scientist. The fact that we're able to make this prediction proves the system's working, says Chesley. These sized objects are not the ones we're most concerned about - there are tens of thousands of much larger objects that could cause real damage on the ground that are still yet to be found. Despite the advanced warning, there is probably too little time to mount a mission to observe the atmospheric impact from an aeroplane, as sometimes happens during known meteor showers, says Milani. But now that this is out in the public, anybody who has a telescope is going to be pointing it in that direction, Chesley says. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Small Asteroid to Light Up Sky Over Africa (2008 TC3)
Oct. 06, 2008 Dwayne Brown Headquarters, Washington 202-358-1726 [EMAIL PROTECTED] Veronica McGregor Jet Propulsion Laboratory 818-354-9452 [EMAIL PROTECTED] RELEASE: 08-254 SMALL ASTEROID TO LIGHT UP SKY OVER AFRICA WASHINGTON -- An asteroid measuring several feet in diameter is expected to enter the atmosphere over northern Sudan before dawn Tuesday, setting off a potentially brilliant natural fireworks display. It is unlikely any sizable fragments will survive the fiery passage through Earth's atmosphere. The event is expected to occur at 5:46 a.m. local time (10:46 p.m. EDT Monday). We estimate objects this size enter Earth's atmosphere once every few months, said Don Yeomans of the Near-Earth Object Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The unique aspect of this event is that it is the first time we have observed an impacting object during its final approach. The small space rock, designated 2008 TC3, will be traveling on an eastward trajectory that will carry it toward the Red Sea. Observers in the region could be in for quite a show, Yeomans said. When the object enters the atmosphere, it could become an extremely bright fireball. The small space rock first was observed by the Mount Lemon telescope of the NASA-funded Catalina Sky Survey early Monday. NASA detects and tracks asteroids and comets passing close to Earth. The Near Earth Object Observation Program, commonly called Spaceguard, plots the orbits of these objects to determine if any could be potentially hazardous to our planet.

[meteorite-list] UA Scientists Discover Tiny Asteroid That Will Hit Earth Tonight (2008 TC3)
FROM: Lori Stiles (cell - 360-0574; [EMAIL PROTECTED]) UA Scientists Discover Tiny Asteroid That Will Hit Earth Tonight University of Arizona October 6, 2008 University of Arizona scientists last night discovered a very small asteroid that is on course to hit Earth tonight at about 7:45 p.m. MST in northern Sudan. The asteroid is too small to be hazardous. But it is the first time astronomers have discovered an object with a nearly 100 percent chance of hitting the Earth. The tiny space rock is only two meters in diameter and is traveling at 12 kilometers per second, said Ed Beshore of UA's Catalina Sky Survey. Whether it will survive entry through Earth's atmosphere depends on its composition, Beshore said. But it is sure to create a spectacular sight for those fortunate enough to see it at night. The asteroid is expected to release about one kiloton of energy, either in a single shot or in a series of explosions, when it hits Earth's atmosphere. It is on course to hit Earth's atmosphere with a grazing strike, much like a skipping stone on water, rather than make a direct hit, Beshore said. It's probably important for people in that area of the world to know that this is not anything other than a natural phenomenon, Beshore said. We're all watching pretty closely. The Jet Propulsion Laboratory's Near Earth Object Observations Program carefully monitors observations from surveys like Catalina as well as those from individual observers. From this data researchers can determine orbits and the likelihood of a collision with the Earth. Richard Kowalski, a member of the Catalina Sky Survey team, discovered the object with the team's 60-inch telescope on Mount Lemmon in the Santa Catalina Mountains north of Tucson. Amateur Italian astronomers are well positioned to see the impact and may get pictures of it tonight, Beshore said. Roughly one out of every 20 asteroids is iron, so this one is probably a stony asteroid, Beshore said. Even if this asteroid is iron and reaches the ground intact, the predicted impact area is largely uninhabited, and the danger to individuals is small. The Catalina Sky Survey last year broke all records for discoveries of near-Earth objects, or NEOs. The survey found more than 450 NEOs in 2007.
