We were a team which had reached Orissa just Meteoric hit, this event happened around 18:30 hours local time (13:00 UT). The description of this event is as follows: around 18:30 hours the eastern sky was so brightly lit it was like a local afternoon the brightness was so strong that many rushed indoors. Over few hundreds of thousands were witness to this spectacular FIREBALL event. The luminous ball was bluish white, crackling and making a lot of noise intial people thought that it could have some rocket which was being tested nearby site. But that was not the case.. it was truly a a great fireball event of the century, said Inspector of Police at Baripada. The area where this fireball must have burst forth, has covered over 8 districts, measuring an area of about 14 to 15 thousand square kilometers. We visited the site wherein the meteorite passed over a hut in Sudsudia, Kaptipada, the roof of the hut was totally burnt and we were able to recover some residue of the meteor. On further investigation we also heard that where the meteor fell in nearby pond, and this water in the pond was boiling. We were able to recover more meteoric residue along with burnt ashes of the roof. We covered nearly 4 district and were able to see meteorite samples from 3 districts, and did recover the meteorite samples from Purab Suniti, Kenrapara district. The results of 'Juganatha meteorite' is in Publication with CURRENT SCIENCE. We are now trying to determine the orbit parameters based on meteorite impact craters formed in Paschim Suniti, Purab Suniti, Jubna all in Mahakalpada region we had seen more than 4 craters in this region, the largest meteoric crater Balbhadra crater was the largest. The region where there several craters formed is in the paddy fields many of them have been washed away. However we are looking for satellite data over India on that day, this might help in determining the actual brightness magntude for this event. Brian Marsden ruled out that Near Earth Asteroid 2003SQ222 which came close to Earth, 10 hours prior to this event. But the event was of larger magnitude then the Tagish Lake in Canada. The work is still in progress any other details can be provided. You can discuss this further here: [EMAIL PROTECTED] Bharat Adur -- End of Original Message --- __ Do you Yahoo!? Friends. Fun.

[meteorite-list] Cometary Meteorites
Hello All, David wrote: Material of cometary origin didn't get a mention. and: ... is this thought to be because comets are largely composed of volatile material - which seldom survives atmospheric entry? David Entwistle Bob responded: The answer to both of your questions is, Yes! In their invited review, H. Campins and T.D.Swindle conclude that comets do indeed yield macroscopic meteorites, which either have not been found or have not been recognized. The mineralogy of potential cometary meteorites would be dominated by highly unequilibrated anhydrous silicates with a nearly chondritic chemistry plus a high abundance of C and N. If an unknown process did produce extensive aqueous alteration in the meteoritic-cometary material, such meteorites they would resemble (or could even be) Cl carbonaceous chondrites. The authors do not expect cometary meteorites to have chondrules - nor CAIs. Cometary meteorites are most likely to come from the Kuiper belt, beyond 30 AU. Orbital considerations make the Oort Cloud comets (10 000 AU and beyond from the Sun) unlikely sources for meteorites. Asteroidal and cometary parent bodies capable of delivering meteorites to the Earth's surface would most likely have similar orbits. 3200 Phaethon has been identified as the parent body of the Geminid meteor shower and there are a number of arguments in favor of a cometary origin of 3200 Phaethon. Cometary activity had been detected in minor planet 1979 on prediscovery plates taken in 1949. This is/was Comet Wilson-Harrington 1949 III and its identification (4015 W-H) confirms that some fraction of Earth-crossing asteroids have a cometary origin. The orbit of 4015 W-H orbit has the potential of delivering meteoroids to Earth at relatively low velocities. Although meteor showers are usually not accompanied by falls of meteorites, this is no valid argument against cometary meteorites. The entry velocity of most shower meteors is so high (~28 km/s) that even strong achondrite meteorites would not survive atmospheric entry. The fall of the Cl chondrite Revelstoke (and, of course, Tagish Lake) has the characteristics that the authors would expect for a weak cometary meteorite: - a fireball visually observed for hundreds of kilometers - atmospheric effects measured nearly 1500 kilometers away - less than a gram of friable black rock, dug out from one of several patches of dust-darkened snow on a frozen lake, was recovered - virtually all the material in the fireball was dispersed during atmospheric entry - Ni-rich magnetic dust was collected by dust collectors during the following few days. The Revelstoke fireball was as energetic as the Sikhote-Alin meteorite, which had left several craters, but, interestingly with regard to Tinguska, no craters were observed! Do we have cometary meteorites in our collections? As cometary meteorites are so primitive, they should have no chondrules. Now, there might be several such meteorites that are misclassified as achondrites. Are there any primitive achondrites with chondritic features? Yes, just think of acapulcoites, lodranites, brachinites, etc. ... but : these have igneous textures ... volcanism on comets? Ivuna and intense heat? ... No! The authors also state that *IF* cometary meteorites do contain chondrules, then C-rich, unequilibrated CO and CV, or ordinary chondrites might be good candidates: Mokoia (CV3), Colony (CO3.0), Kaba (CV3), Sharps (H3.4; gas-rich; xenolithic) The authors also examined xenoliths in certain chondrites and found a clast in the H4 Dimmitt regolith breccia that contains C-rich aggregates (up to 13 wt% C) with poorly graphitized C, magnetite, and anhydrous silicates (as expected for cometary material). Yes, I know ... everybody is waiting for Krymka (LL3.1). Of course, Krymka (and Supuhee, an H6 chondrite with similar exotic inclusions!) was one of the highly promising candidates for the authors. Not Krymka itself, but some rare, volatile- rich clasts with roughly chondritic chemistry (this led to the material in the clasts being referred to as mysterite) and a fine-grained matrix identified as organic material. One Krymka clast was richer in noble gases than even CI chondrites ! The authors conclude, and let me quote: We have not identified an individual meteorite that looks unequivocally cometary (i.e., none meet all the characteristics listed in Table 2), although some xenoliths in ordinary chondrite breccias come close. On the basis of studies of cometary fireballs, we should have collected approximately the same number of cometary meteorites as CI chondrites. In other words, given the rapid growth of the world's meteorite collections, we might be on the verge of collecting or identifying a cometary meteorite. Reference: CAMPINS H., SWINDLE T.D. (1998) Expected characteristics of cometary meteorites (MAPS 33-6, 1998, 1201-1211). * Best regards, Bernd To: [EMAIL PROTECTED] [EMAIL PROTECTED]

Re: [meteorite-list] Cometary Meteorites
Hi Bernd and all, I had always heard Murchison was thought to be cometary material. Does this (below - especially the last paragraph) indicate it has been ruled out?
