[meteorite-list] north europe hurrycane emergency
Hallo listers, I'm a bit concerned about our friends in northern europe, especially polish and belgian, where a violent hurrycane caused severe damage and some casualties. I tried and contact Andrzej and Marcin yesterday but haven't received any answer yet. As I'm going to stay out all day, will anyone try and get contact with them if possible, and ask if they need any help? greeting and thanks to all.

Hi Leandro, yes the storm was terrible. I don't have heard of Belgium and Poland, i guess it was most heavy in Germany and England, in Germany we have 11 dead people and England 10, as far as i know. There is much water now in the street i live and many damaged roofs around, broken trees and so on. Nature is going mad...

Re: [meteorite-list] Nininger Moment #25
Nininger Moment #25 The Sale of the Nininger's Collection Part One Since there is a current discussion on the list of where the Nininger Collection is currently at I thought it would be appropriate to generate this Nininger Moment. From the 1920's to the late 1950's Nininger has hunted meteorites and amassed a collection second to none. Hundreds of meteorites had been located, bought and traded to make up what was the Nininger Collection of meteorites. As any collector would do he certainly held on to a number of the most impressive collection pieces out there for himself. Trading other fine specimens for localities that were not yet in his collection and represented other fine falls or finds of that era. In 1957 the years of effort put in by the Niningers began to weigh heavily as their financial survival came into question. The sale of part or all of the Nininger Collection came into play as the Nininger's wanted some financial security and a way of retirement. In 1956 Max Hey, the curator of the British Museum of Meteorites had expressed an interest in Nininger's collection if he should ever want to sell it. The following year the British Museum ask for a an extensive price list for the collection and a vertical split of the collection for the museum. Nininger came up with an initial offering of $258,000 for half of his collection. The British Museum asked for another split of the items offered and asked for no less than half of the value, and asked for cost on cutting and preparation of those specimens. Out of 680 unique falls and finds in the Nininger collection, Nininger offered a 1/4 to 1/2 split on 276 specimens for a price of $155,000 dollars. The British Museum asked for time to raise the money for the collection offered before committing to the purchase. In the mean time and before final acceptance by the British Museum, there was suddenly more interest in Nininger's collection by the Smithsonian and Arizona State University. These two institutions were also needing to find a way to come up with the necessary capital to buy a portion or all of the collection. The Smithsonian suggested a price of $200,000 for the whole collection which Nininger decided would be an appropriate discount rate for the entire collection. The University of Arizona had no internal means and had to look out side for funding in order to make a firm offer. All three parties were notified of interest in the collection by the other parties but no effort was made by Nininger to induce bidding by the parties. After many correspondences and delays of getting any firm offers by the three parties, on June 13th, 1958 came a firm offer in the form of a letter from C.F. Claringbull, keeper of the British Museum. In this letter was an offer to buy the collection as Nininger had proposed (about 1/5 of the Nininger Collection) for a sum of $140,000. After the offer Harvey Nininger cabled confirmation of the request to the British Museum and promptly withdrew from all other offers. Source: Find A Falling StarBy H.H.

Some of the items written in the moments might be old out dated material and the reader is advised to keep this in mind. --AL Mitterling __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Hi Leandro, very nice from you caring about. Yes, it was a handsome hurricane, topspeed ca. 120 miles/h. I live in the southern part of Germany, not far from the Lake of Contance.

Re: [meteorite-list] NASA Spacecraft En Route to Pluto Prepares forJupiter Encounter
Hi Rob, Re:Gravity assist... The amount of gravitational momentum it receives as it passes close in to Jupiter far exceeds that which pulls it back when its gone by and is further away, hence the net result is a sling shot.

Could someone clarify something which ahs been bothering me for years about this gravity assist technique? Why does the spacecraft come out of the gravity well going faster than it went in without thrust? You remember the conservation of energy stuff from school? GravPotential to Kinetic to GravPotential. A ball rolling down a hill can only roll up the other side to a height as high as it was released from. Why does this not apply to spacecraft? It's climbing out of the suns gravity well so it ought to be slowing down all the way. When you drop into Jupiters gravity well I can see that you're going to speed up but on the way out surely it'll lose all that speed and at the end of the encounter should be no faster than it went in at. In fact, slower because it's now further up the hill of the suns gravity well. Please, will someone tell me what I'm missing. It bothers me tremendously that I have a BSc in physics and studied both astronomy and astrophysics subsids and I don't get it. It's the same with asteroids getting ejected into orbits further out.

[meteorite-list] Ensisheim show 2007
Hola List, We are being receiving many inquiries about the dates of the 8th meteorite show Ensisheim 2007. The new circular and edvertisements should have been ready by now, however, unexpected technical (mainly computer) problems are forcing us to delay their public release. In about 3 weeks all should be ready. Info (In French and English) could then be found at our Ensisheim city web site, thus: http://www.ville-ensisheim.fr/ On the other hand, Nick Gessler kindly proposed us to create a specific web site that we could upload with the (English) circular and further info about the show. This should be done quite soon as well. The 2007 edition will be held from Friday June 15 to Sunday June 17. As in the past, we stay connected to the big Ste Marie mineral show that is nearby. Their dealer's days start as early as on Tuesday-Wednesday (June 19-20), in case you wish to attend both shows. The overall space available in Ensishim and table prices did not change. Regarding accomodation, we are happy to anounce that a large brand new hotel (many rooms) has been built in Ensisheim, at 150 m from the show (!). It will officially open this Spring but reservations can be made from now on. Prices are as fair as in the more traditional Niemerich and La Couronne, thus in the 70 euro range for double rooms breakfast included. (I have all the details, phones, faxes... available, please inquire). For those wanting to rent a car, we can provide info. The best tip is, for overseas guests, to fly to Zürich (international) with a short flight connection to Basel, that is the nearby airport (about 25 km from Ensisheim and less than 20 km from Mulhouse). Avoid flights to Paris if your purpose is specifically Ensisehim or Ste Marie. The topic (theme) emphasized in 2007 will concern the strange meteorite external shape and morphologies and their fascinating internal odd textures (title still to be refined). It will be supporetd by 2 lectures. The internal wonders (breccias, CAI's, unusual chondrules...) will be illustrated by super slides of thin sections taken by our first lecturer and new expert Roger Warin. The lecturer willing to describe and explain external features (orientation, crust, odd morphologies, grooves, holes, inclusions, clasts) is still badly wanted. If not found soon (are there voluntaries ?), either Sabine Valange or myself could take this responsibility (and pleasure) and tell you something about this, in a short talk. Many oddly shaped meteorites ande section in the corresponding exhibit (Regency Museum) will anyway speak by themselves, probably more than dozens of pictures and thousand words. The wild card will, this time, be given to Alain Carion and Pierre-Marie Pelé, who proposed to display exclusively their brand new (old) French meteorite, with a lot of (historical) data. I must also apologise for my 5 days silence on mail as many of you expected specific answerf from me. Our server did not cooperate this week and I lost (but partly found) many of my recent posts. Things gradually settle and I should be again in full contact next week. Have a nice Tucson fun all! Wish being with you but, besides the very busy schedule at work, I can't really decide is I prefer huge storms with mild temperatures here or your cold wave (snow ?) that showed these last days even in the deserts (kidding...). Storm restricted yesterday to (only) max 100 km/hour winds here in Mulhouse. I will now drive to Belgium and be there within the next 6 hours, hoping to see restricted damage.

[meteorite-list] The Extravagant Tail of Comet McNaught
Space Weather News for Jan. 19, 2006 http://spaceweather.com Last night at sunset, motorists in South Africa pulled over to watch what seemed to be a bush fire. As the twilight deepened, however, they realized it was something else: the extravagant tail of Comet McNaught. Even experienced astronomers say they've never seen anything quite like it. McNaught's tail materializes at sunset in the southern hemisphere and is visible to the unaided eye as a majestic fan of pale streamers. The comet itself is visible only from the southern hemisphere, but its tail sweeps all the way back into northern skies. People in California, Colorado and Hawaii have seen it peeking above the western horizon about an hour after sunset. This northern tail is faint but pretty, and resembles a pale aurora borealis.

People in California, Colorado and Hawaii have seen it peeking above the western horizon about an hour after sunset. This northern tail is faint but pretty, and resembles a pale aurora borealis. (Dark skies are absolutely required.) Over the course of the last 2 weeks, my husband and I have been trying to view Comet McNaught, to no avail. This was most peculiar, since most days we have a clear view of the horizon at sunset, but the days when we could look, there was usually a band of clouds to the west, and other days, we forgot or got too busy. I've even been looking in the a.m. just before dawn, since we have a very effective sun filter in the form of Haleakala, but the only thing I've seen has been some very nice crepuscular rays. No comet. I'm starting to feel very put upon. Has anyone else viewing from Hawaii been able to see it? It's a conspiracy, I tell ya!

The patterns of typical MG eucrites such as Bereba and Jonzac, are rather flat with a significant Cs and Rb enrichment. The patterns of NL eucrites (Nuevo Laredo, Lakangaon, Igdi, Sahara 02501) exhibit higher incompatible element concentrations, and Sr and Eu negative anomalies, in agreement with their more evolved compositions. (Note that high Ba and Sr abundances in Saharan finds are produced by alteration [9]). The Stannern trend eucrites (Stannern and Bouvante)are not only richer in in compatible trace element than the other eucrites, but their trace element patterns are clearly distinctive, with pronounced negative Be, Sr and Eu anomalies. As is the case for the MG-NL trend eucrites the behavior of alkali elements seems somewhat erratic, and has not yet been properly explained (fingerprints of impact processes?

[meteorite-list] The Greatest Comets of All Time
http://space.com/spacewatch/070119_ns_great_comets.html The Greatest Comets of All Time By Joe Rao SPACE.com 19 January 2007 Last week favorably placed observers viewed a comet so brilliant that it could be seen with the naked eye in broad daylight, if the Sun was hidden behind the side of a house or even an outstretched hand. Comet McNaught, which was discovered last August by astronomer Robert McNaught at Australia's Siding Spring Observatory, was one of the greatest comets in recent times. It evolved into a brilliant object as it swept past the Sun on Jan. 12, at a distance of just 15.9 million miles. The comet's show is mostly over for those North of the equator. Yet even as the comet puts on a fantastic show now in the evening sky for viewer's in the Southern Hemisphere (McNaught himself produced a fantastic photograph http://www.space.com/php/multimedia/imagedisplay/img_display.php?pic=070119_mcnaughts_pic_02.jpgcap=Robert+McNaught,+the+Australian+who+discovered+this+comet+that+bears+his+name,+finally+got+to+photograph+it+this+week+when+it+became+visible+from+the+Southern+Hemisphere.+Image+used+with+permission), an incredible sight is still visible to seasoned observers in the Northern Hemisphere. From Colorado, Mary Laszlo of used a 20-second exposure to capture the outer extremities of Comet McNaught's tail http://www.space.com/php/multimedia/imagedisplay/img_display.php?pic=070119_mcnaught_lazlo_02.jpgcap=From+Colorado%2C+Mary+Laszlo+of+used+a+20-second+exposure+to+capture+the+outer+extremities+of+Comet+McNaught%27s+tail+on+Jan.+17%2C+2007.+Paul+Robinson+of+Boulder+was+credited+as+having+realized+such+an+image+might+be+possible.+Credit%3A+Mary+Laszlo on Jan. 17. Paul Robinson of Boulder was credited as having realized such an image might be possible. Brighter than Venus According to reports received from a worldwide audience at the International Comet Quarterly (ICQ) it appears that the comet reached peak brightness on Sunday, Jan. 14 at around 12 hours UT (7:00 a.m. EST). At that time, the comet was shining at magnitude -5.1. On this scale, larger numbers represent dimmer objects; the brightest stars are generally zero to first magnitude, while superbright objects such as Venus - and Comet McNaught - achieve negative magnitudes. I determined the comet's peak magnitude by averaging out more than a dozen observations that were reported to the ICQ on Jan. 14. Some observers, such as Steve O'Meara, located at Volcano, Hawaii, observed McNaught in daylight and estimated a magnitude as high as -6, noting. The comet appeared much brighter than Venus! From Jan. 12-16, Comet McNaught ranked as the third brightest object in the sky behind only the Sun and the Moon! Was Comet McNaught the best or brightest comet ever seen? While it's true that comets that are visible with the naked eye during the daytime are rare, the case of McNaught is not unique. In the last 263 years, it has happened seven other times: GREAT COMET OF 1744: First sighted on Nov. 29, 1743 as a dim fourth magnitude object, this comet brightened rapidly as it approached the Sun. Many textbooks often cite Philippe Loys de Cheseaux, of Lausanne, Switzerland as the discoverer, although his first sighting did not come until two weeks later. By mid-January 1744, the comet was described as 1st-magnitude with a 7-degree tail. By Feb. 1 it rivaled Sirius and displayed a curved tail, 15-degrees in length. By Feb. 18 the comet was equal to Venus and now displayed two tails. On Feb. 27, it peaked at magnitude -7 and was reported visible in the daytime, 12-degrees from the Sun. Perihelion came on March 1st, at a distance of 20.5 million miles from the Sun. On March 6, the comet appeared in the morning sky, accompanied by six brilliant tails which resembled a Japanese hand fan. GREAT COMET OF 1843: This comet was a member of the Kruetz Sungrazing Comet Group, which has produced some of the most brilliant comets in recorded history. It passed only 126,000 miles from the Sun's photosphere on Feb. 27, 1843. Although a few observations suggest that it was seen for a few weeks prior to this date, on the day when it made it closest approach to the Sun it was widely observed in full daylight. Positioned only 1-degree from the Sun, this comet appeared as an elongated white cloud possessing a brilliant nucleus and a tail about 1-degree in length. Passengers on board the ship Owen Glendower, off the Cape of Good Hope described it as a short, dagger-like object that closely followed the Sun toward the western horizon. In the days that followed, as the comet moved away from the Sun, it diminished in brightness but the tail grew enormously, eventually attaining a length of 200 million miles. If you were able to place the head of this comet at the Sun's position, the tail would have extended beyond the orbit of the planet Mars!

Hi all, Just been weathering the storms here in the UK...luckily the Midlands seems to have escaped the worst. The West was hit bad though...think the death toll is up to 13 now. Many towns still without power. As you may have all heard, after departing the UK the storm headed into Europe and worstened again...most unusual...hope everyone out there is ok. I spent today doing a trade for three samples of rarely available meteorites. I have aquired a large slice of Wairarapa, an H6 from New Zealand (looks brecciated or shock melted to me) around 40g I think. Plus several pea sized fragments of , a well documented CV3 fall in 1908 again from New Zealand and finally a fragment (about 30g) of Alta ameem LL5, fell in 1977 , about 100 m N. of the village of Humaira, northern Iraq. I have photographed the labels and original notes from when they were aquired in the 60's and 70's to show thier provenance. I was told that they resided at Newcastle University until recently when a deparment closed and they were passed on tho the present collection. I have managed to put Wairarapa through the SEM this afternoon and am now trying to make sense of the images and data. I have no experience in doing this... If anyone out there has such experience and would like to see the data I would be glad of any pointers as to recognizing the minerals from the elements present. I will try and find a way of posting some photographs of the samples and supplying links to them if anyone is interested. Meanwhile Tucson grows ever closer...just one week before we fly. Hope to see some of you there. Graham, Nr Barwell UK __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Deadline (ad)
Please note. I have only 17 more slots for the auction. If you want your item advertised you MUST submit your photo and description within the week. Also, if you are wanting to make any absentee bids this week is FAR better than calling me on my cell phone after I have left for Tucson!
