The line of conducting plasma would short circuit the heavily charge separated areas (Charges migrate due to the supercooled freezing process). I think you would get a nice lightshow.

More like L5-6 imho... seems an awful lot of metal in some pics I've seen..

Re: [meteorite-list] Meteoroid/Asteroid Electro-Magnetic Disruption and Charge Properties?
In plasma situations where electrons and nuclei are freely moving about, the math supports a very, very tiny chance that nuclei will collide with enough energy to merge or break apart into other isotopes. Applying a rate of trillions of possibilities in a volume, over a period of time, the probability becomes realizable that somewhere, something happened. There's a whole sub-culture of people who build fuzors in their garages for the novelty of saying there's a chance something is fusing in that glowing cloud. --- On Thu, 2/28/13, Pict p...@pict.co.uk wrote: From: Pict p...@pict.co.uk Subject: Re: [meteorite-list] Meteoroid/Asteroid Electro-Magnetic Disruption and Charge Properties?

Jorge, 1) I am not selling any material from this fall, nor do I plan to. 2) So much of the material you're selling in your ebay account is so painfully misrepresented that I fear no threat from you. You're either woefully ignorant, or a cheat. Either way, you have no grounds to be threatening anyone who points this out. Written proof is worth as much as the person who's writing it, which means nothing in your case. You sell common NWA's as meteorites from Oman, Burkina Faso, and the Atacama, have already sold a piece of an H-chondrite as Chelyabinsk material: http://www.ebay.com/itm/Chelyabinsk-RUSSIA-2013-Meteor-Event-1-20gr-Very-Rare-Meteorite-Specimen-/321079087502?pt=LH_DefaultDomain_0hash=item4ac1ce118e To say nothing of the mislabeled Canyon Diablo, Sikhote Alin, and several smaller specimens of rare falls that you've listed in recent months that have consisted of caliche-encrusted fragments of NWA meteorites. At any given point, I'd say about a third to a half of your non-NWA material is misrepresented (or perhaps accidentally mislabeled, but the end result is the same). You're trying to make money off of the people in our community by deceiving us. I wouldn't expect mush sympathy here. Jason From: Jorge M.

I would suggest refunding the buyer of the 1.20 gram fragment you've already sold and pulling the 19 gram stone.

February 15 morning residents of several regions of the Urals observed the meteor, and then there was a flash and a powerful explosion . The shock wave damaged buildings and knocked out a lot of glass in Chelyabinsk, and more than a thousand people were injured. A Ural Federal University expedition discovered earlier in Lake Chebarkul meteorite particles, and chemical analysis showed that in the Urals were ordinary chondrites - a type of stony meteorite. Expedition laboratory Meteoritics Institute of Geochemistry and Analytical Chemistry, Russian Academy of Sciences Vernadsky delivered to Moscow about 1.5 kilograms of meteorite fragments. According to Nazarov, to date, the first phase of the research of submitting an application of the meteorite to the international catalog have been completed. This is an ordinary chondrite type LL5, shock fraction S4. Such meteorites are relatively rare, in the flow of ordinary chondrites are only about 2%. Our territory of previously observed, - said the source. LL chondrites are low in iron and other metals, as well as relatively large chondrules (rounded grains, which got its name: chondrites). Figure 5 is a petrological class, indicating the kind of geochemical changes undergone a meteorite. In Russia, this type of of meteorite has never been found before. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Like I have said many times. Collector confidence is at an all time low when it comes to new falls due to a few bad people. It only takes one person substituting material from one fall to totally ruin the confidence in another. This is the main reason I no longer collect recent falls or chase them for that matter. Even genuine material comes under unnecessary scrutiny and is assumed fake before being proven real in many cases. I think dealers shouldn't assume somebody is guilty without it being blatantly obvious. It is not the American way to assume somebody is guilty before being proven innocent. Many have forgotten American history and should crack the books!

This info completes the official flyer that will be ready in a couple of weeks and that I will be glad to forward you individually, upon request. Further show details will be also sent to the List in a couple of months, as every year. Here are just the main changes useful for those wishing to book tables and foresee specific arrangements. SHOW DATES: Saturday June 22 (9:30-18:00) and Sunday June 23 (9:30-16:00), 2012 (the weekend preceding the “Mineral Gem” show that is held in Ste Marie-aux-Mines, relatively nearby (~ 80 km), with Friday June 21 as the “dealer’s day”). SHOW LOCATION: Exceptionally this year, THE SHOW LOCATION MUST BE CHANGED! Indeed, the famous Regency Palace which is the usual and unavoidable place to set the show, is subject to heavy works that unfortunately will not be completed by the due date. While the external buildings are expected to be reconditioned, the interior halls will by no means be accessible in June: all the rooms and corridors will be restored and repainted while an elevator (lift) will be built so as to facilitate the rise and handling of your heavy meteorite boxes in future. (Hey, never worry, the famous medieval spiral staircase will stay untouched). Naturally in 2014, for the 15th Anniversary of the show coinciding with the 30th Anniversary of the Confraternity of Guardians creation, a brand renovated Regency Palace will welcome you again! For 2013 (only) we have obtained another separate building called “FOYER St MARTIN”, which is located quite close (about 350 m) to the Regency palace, and just separated from the “Domaine du Moulin” hotel by the main street (distance ~150 m). You can find the place, the building picture and the access map in the following link: http://www.jds.fr/agenda/manifestations/expo-bourse-aux-meteorites-2013-a-ensisheim-53539_A The “Foyer” consists in one large 18.6 x 12 meter room, resembling the Regency main hall, though larger. The usual 160x80 cm tables will be arranged similar to the Regency arrangement, namely all around the walls and also arranged in a “middle square”. The daylight basically comes from the glass ceiling, and will provide a uniform illumination (personal lighting is always allowed). This means that the characteristics (light etc) of every place in the hall will be practically the same. A small bar, dressing room, telephone room, restrooms … are adjacent to the main hall. Opposite the entry is a podium accessible from both hall sides by 2 staircases. The podium will host the genuine Ensisheim meteorite in its display window, the thematic exhibit (Meteorites from Antarctica – see below) and the consignment room, all visible from the main floor. 3 doors on the west side lead to a large terrace (18x8 m) where at least 4 tents will be erected, each containing 4 dealer tables. The terrace itself adjoins a large park providing all the usual facilities (tables for food, leisure, snacks, tent for dinner party, enthroning ceremonies, Friday friendly drink, every day drinks, music, beverage bars, dance…). In fact, all what was set on the Regency main square will be shifted to that park next to the “Foyer” terrace.
[meteorite-list] Scientists at Princess Elisabeth Antarctica Discover 18kg Antarctic Meteorite
http://www.antarcticstation.org/news_press/news_detail/scientists_at_princess_elisabeth_antarctica_discover_18kg_antarctic_meteori/ Scientists at Princess Elisabeth Antarctica Discover 18kg Antarctic Meteorite International Polar Expedition Press Release February 28, 2013 A team of scientists working at Princess Elisabeth Antarctica have recently discovered a meteorite weighing 18kg embedded in the East Antarctic ice sheet, the largest such meteorite found in the region since 1988. The eight members of the SAMBA project, from Universite Libre de Bruxelles (ULB) and Vrije Universiteit Brussel (VUB), Japan's National Institute of Polar Research (NIPR) and Tokyo University were searching for meteorites scattered across the Nansen Ice Field on January 28, when they found the 18kg ordinary chondrite. The team discovered a total of 425 meteorites, with a total weight of 75kg during the 40 day expedition, at an altitude of 2,900m, 140km south of Belgium's Princess Elisabeth Antarctica research base. This meteorite was a very unexpected find for us, not only due to its weight, but because we don't normally find such large meteorites in Antarctica, said Vinciane Debaille, a geologist from Universite Libre de Bruxelles, who led the Belgian team during the expedition This is the biggest meteorite found in East Antarctica for 25 years, so it's a very special discovery for us, only made possible by the existence and location of Princess Elisabeth Antarctica. The SAMBA project contributesto the US and Japan-led global collection of Antarctic meteorites, and is an initiative of VUB and ULB, in collaboration with the Japanese Institute of Polar Research. SAMBA is supported by the Belgian Science Policy (BELSPO) and the International Polar Foundation. Initial field analysis by the scientists suggests that the 18kg meteorite is an ordinary chondrite, the most abundant kind of meteorite. The fusion crust - the meteorite's outer casing - was eroded, allowing the scientists to inspect the rock underneath. The meteorite is currently undergoing a special thawing process in Japan - to ensure water doesn't get inside the rock - but will be brought to Belgium in the future. We study meteorites in order to better understand how the solar system formed, how it evolved, how the Earth became such a unique planet in our solar system, said Debaille. This season's SAMBA mission was a success both in terms of the number and weight of the meteorites we found. Two years ago, we found less than 10kg. This year, we found so much that we had to call the travel agency - because we had 75kg of meteorites to take home. Princess Elisabeth Antarctica is the world's first zero emission polar research station, and is operated by the International Polar Foundation, in partnership with the Belgian Polar Secretariat. Princess Elisabeth Antarctica's design and construction seamlessly integrates passive building technologies, renewable wind and solar energy, water treatment facilities, continuously monitored power demand and a smart grid for maximising energy efficiency. Located in East Antarctica's Sor Rondane Mountains, Princess Elisabeth Antarctica welcomes scientists from around the world to conduct research in this little-studied and pristine environment. Both Princess Elisabeth Antarctica and the International Polar Foundation are proud to support the research work of the Belgian and Japanese meteorite team, said expedition leader Alain Hubert. By providing solid logistics and field accomodation solutions to scientists working on the ice, we can ensure they can concentrate on what they have come to Antarctica to achieve: unlocking of Nature's mysteries and broadening understanding of our planet.

[meteorite-list] Computer Swap on Curiosity Rover
http://www.jpl.nasa.gov/news/news.php?release=2013-078 Computer Swap on Curiosity Rover Jet Propulsion Laboratory February 28, 2013 Mars Science Laboratory Mission Status Report PASADENA, Calif. - The ground team for NASA's Mars rover Curiosity has switched the rover to a redundant onboard computer in response to a memory issue on the computer that had been active. The intentional swap at about 2:30 a.m. PST today (Thursday, Feb. 28) put the rover, as anticipated, into a minimal-activity precautionary status called safe mode. The team is shifting the rover from safe mode to operational status over the next few days and is troubleshooting the condition that affected operations yesterday. The condition is related to a glitch in flash memory linked to the other, now-inactive, computer. We switched computers to get to a standard state from which to begin restoring routine operations, said Richard Cook of NASA's Jet Propulsion Laboratory, project manager for the Mars Science Laboratory Project, which built and operates Curiosity. Like many spacecraft, Curiosity carries a pair of redundant main computers in order to have a backup available if one fails. Each of the computers, A-side and B-side, also has other redundant subsystems linked to just that computer. Curiosity is now operating on its B-side, as it did during part of the flight from Earth to Mars. It operated on its A-side from before the August 2012 landing through Wednesday. While we are resuming operations on the B-side, we are also working to determine the best way to restore the A-side as a viable backup, said JPL engineer Magdy Bareh, leader of the mission's anomaly resolution team. The spacecraft remained in communications at all scheduled communication windows on Wednesday, but it did not send recorded data, only current status information. The status information revealed that the computer had not switched to the usual daily sleep mode when planned. Diagnostic work in a testing simulation at JPL indicates the situation involved corrupted memory at an A-side memory location used for addressing memory files. Scientific investigations by the rover were suspended Wednesday and today. Resumption of science investigations is anticipated within several days. This week, laboratory instruments inside the rover have been analyzing portions of the first sample of rock powder ever collected from the interior of a rock on Mars. NASA's Mars Science Laboratory Project is using Curiosity to assess whether areas inside Gale Crater ever offered a habitable environment for microbes. JPL, a division of the California Institute of Technology in Pasadena, manages the project for NASA's Science Mission Directorate in Washington.

Re: [meteorite-list] sharp protrusion from an iron meteorite
Hello Adam, All, Actually, Uruacu does appear to be distinct from Campo del Cielo. Uruacu appears to be a much older meteorite that has weathered in different conditions, and many individuals show cohenite when cut -- a mineral I have never seen in Campo del Cielo. Generally speaking, Campos run the full range from freshly-fusion crusted to rusty lumps, and everything in-between. But, Campo fell within the past ~5,000 years, so we're talking about rapid weathering in a wet environment (also why it's a ruster). Uruacu fell in a drier area, and most individuals exhibit a much more uniform covering of shale that does not readily flake off due to rusting. They seem to have fallen much longer ago, and are generally more weathered due to the fact that they've been around for longer. Uruacu generally resists rusting better. It would be like comparing Sikhote Alin to Henbury. No Henburies I know of rust, but, by and large, they're not as fresh as most Sikhotes. But some Sikhotes appear to have fallen into swampy areas and look pretty bad -- and rust. It's hard to mix the two up. The trouble is that I've also seen Campos sold as Uruacu, which complicates things. Uruacu is a very old fall. Even some reputable dealers have been selling specimens of new Campo (crust, regmaglypts) as Uruacu. Very different. I assume this is due to dishonest suppliers. There's a stunning, fairly large Uruacu for sale at the moment. Not mine, but I wonder if this will bring it out of the woodwork.
