As a police officer in a tourist area I meet a lot of interesting people passing through. Met a gentleman today who was a witness to the Monahans meteorite. He stated that it passed over just before sundown and was visible for about ten seconds and lit up the sky. He was approx. 90 miles from the impact site and thought it hit within a couple of miles of his location. He witnessed it while walking his dog near Big Spring, TX.

[meteorite-list] Nininger and Perry Letter's - Intermission 1
Hello list, I have decided to put little intermissions in between the letters which will allow me to comment or answer e-mails, which not making me reply to every e-mail, and keeping it easier to follow for you archive lurkers. Since this is intermission we should relax our eyes a little. If you have been in front of the computer for over an hour, turn your head to the side and focuse on something across the room for 30 seconds. Trust me this is good for you. The snack bar is now open. It is hard not to respect Nininger. He was by far from a perfect man and some of the things he did or might have done, could be considered unethical or at the least not right. It is hard to credit Nininger with having all these correct ideals. Do not get me wrong, whatever you are thinking meteorite wise, Nininger likely wrote three articles on it and found the type specimen. But it would be fair to say that many of his ideals were wrong. But Nininger had, if I dare use such a relic word, spirit. He was also not afraid to ask questions. He was not afraid of a little field work. He was not afraid to work against the grind. What Nininger did best was promote meteorite interest. If you have read "Find a Falling Star", you know the story of his struggle and his desire to build an institution for meteorite research. The Harvey Nininger - Stuart Perry letters verify and back up much of Nininger autobiography and his fight. I do not want to spoil the letters so i will refrain from letting you know history out of order and stop here. Understand that Nininger had a dozen Stuart Perry's. And it is only because of these Perry's that Nininger was able to do the things he did. I have always found the humanistic side of meteorites as interesting as the scientific side. By sharing the Nininger - Perry letters I hope you gain a little more understanding into Nininger and perhaps pick up a little more interest yourself. Harvey, if your up there..could you make the next fall be in Wichita, Kansas?

TSCHERMAK G. (1885) Die mikroskopische Beschaffenheit der Meteoriten (Stuttgart E. Schweizerbart'sche Verlagshandlung, E. Koch, 23 pp.). English Translation: The Microscopic Properties of Meteorites, Vol. 4, No. 6 (Smithsonian Contributions to Astrophysics, Washington, D.C., 1964). Translation by J.A. Wood and E.M. Wood Chladnites This combination of minerals has been found in only one meteorite, Bishopville. The stone is coarse-grained and consists mostly of friable snow-white enstatite. Rose observed other white grains, but could not identify them. I find these to be plagioclase. The third constituent is pyrrhotite. The stone's crust has a marbled appearance, being partly colorless, partly black, white, bluish, and gray. Enstatite occurs in large and small grains, mostly large. I observed distinct crystal boundaries on one of the small grains ...The grains are cut by many fine, irregular cracks (in addition to the cracks that were produced during preparation of the thin- section). Inclusions are rare and consist of opaque grains, less often of black needles. Plagioclase is usually attached to the small enstatite grains. I have not found plaogioclase with a regular crystal boundary. Its outlines are rounded, lobate, or elongated. In polarized light a very distinct twin structure is sometimes seen, consisting either of alternating wide and narrow lamellae, or entirely of extremely narrow lamellae having a finely-ruled appear- ance between crossed Nicols. Most untwinned plagioclase grains show undulose extinction; many are aggregates of several small grains. The identification of this mineral as plagioclase is based on its behavior in polarized light. An attempt to separate individual grains from the stone for further tests was unsuccessful, not only because of their small size but also because they could not be distinguished by color or luster from the enstatite. In places, the plagioclase shows streaks and slight cloudiness and is brownish by transmitted light. Small opaque inclusions are rare, but larger, often spindle-shaped, bronzite inclusions are abundant. Pyrrhotite forms large and small grains; in the specimen studied these grains are surrounded by brown areas, the result of reaction with the atmosphere. The analysis of Rammelsberg (1861), which found Al2O3, CaO, and alkalis in small amounts, in addition to the ingredients of enstatite, is in full agreement with the microscopic description just given. Rose also reports small amounts of nickel--iron and a black mineral that sometimes fills fine cracks. Breaking the stone along such cracks, I observed a shiny material, similar to that in meteorites to be described later, in which the veins consist of iron, pyrrhotite, and silicate glass. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

There are many different unpaired meteorites from Gold Basin. I didn't mean to claim that all of the meteorites from there are the same. I was just refering to paired samples of Gold Basin that have gone into universities and broadened the understanding of the Gold Basin meteorite as a whole. We, in the south west, live in a great area for meteorites and meteorites have been falling for a long time. The meteorites love our droughts and the pittiful rain when it does fall. I can't wait to see the classifications that come out the Franconia area. Ten or so new ones would give a great boost the Arizona total and show other states that we have meteorites too (hehe).

Apparently the List was down yesterday when I orginally sent my reply to Tracy, and since then Devin has done a good job of answering Tracy's question. But I'll resend this anyway, because I want to pesonally extend kudos to Rubin and Mike for the good job they have done in the handling of their Franconia/Buck Mountain/Dutch Flat Area meteorite finds:-- Bob V. - Date:Fri, 9 Apr 2004 18:27:10 -0700 (PDT) From: "Robert Verish" <[EMAIL PROTECTED]> Subject:Re: Franconia Area Meteorites To: "Meteorite-list Meteoritecentral" <[EMAIL PROTECTED]> We shouldn't exclude from the Gold Basin Area list all of the "Gold Basin L5" and the "Gold Basin L6" stones, because I think this is what Tracy was referring to. Acceptance of these names has met with resistance, (myself included), yet there is no denying that these are formally approved names (I have the message from Jeff Grossman that formally approves their usage). But the point to be remembered here is that all of these various L-meteorites from Gold Basin are deemed by the NomComm to be from the same fall. That's why they lumped all of them together under the name "Gold Basin". But it is doubtful that this "special case" for Gold Basin will have any bearing on the naming of Franconia area meteorites. Here there is ample evidence of separate falls, if not overlapping strewn fields. So, based on the reports of Rubin Garcia & Mike Miller - that ASU estimates ~10 different chondrites from this area - the typical response to the phrase "Franconia meteorite" will be "Okay, but WHICH Franconia meteorite?" And who gets to decide which ones are paired? Also, I don't feel it's "safe to assume" that enough Franconia specimens are being properly examined, let alone classified. And that's why the effort put forward by Garcia & Miller is so notable; it's because they are the exception, and not the rule. They deserve major kudos for this effort in getting so many of their specimens examined and classified. It's because of this effort (and they're being local to Franconia) and ever since Mike contacted me back in November about their new finds, that I have been slowly winding down my involvement with this locality. So I agree with John, if anyone has any questions regarding the types of meteorites being found in this "hot-spot", you should contact Ruben or Mike. I've already mentioned in a previous post that, if you have a Franconia specimen that you want examined, you should forward it to ASU Center for Meteorite Studies. And finally, about my slices of Franconia (H5), I would feel more comfortable if we were to refer to this stone the John Wolfe meteorite, since he is the finder of that stone. My involvement with that stone was supposed to be temporary. It was my intention, after getting it classified for John, to keep that stone in Arizona - in the ASU collection. But after more than a year of negotiating, they ended taking an unclassified specimen from a meteorite dealer. I would still prefer to see Franconia (H5) kept in Arizona, but what is Arizona's loss might become some collector's gain.

[meteorite-list] Perry to Nininger Letter, June 1, 1951
(Stuart Perry to Harvey Nininger letter, Perry's File copy) June 1, 1951 Dear Nininger: You must be thinking by this time that I have gone to sleep on the Peru iron, but that is not the case. I wanted to have Herbenar's interpretation of certain structures, and after very long delay I now have the date from him, along with the photos which I am inclosing to you. The iron is very usual, in fact almost anomalous, because it seems to have a definite iron-carbon structure and to contain abundant inclusions of steadite -- Fe-Fery-Fe-Fe3C-Fe3P eutectite found in artificial irons but which I have never seen observed in a meteoric iron with the exception of the small area in Chesterville. Herbenar feels very certain there these strange inclusions are Steadite, and that this would be confirmed by microchemical analysis -- in other words by selective etching for carbon and phoephorus. To take up a few of the photos - 1, 3 to 8, and others, show the strange looking streadite inclusions. 12 and 14 show the transitory interface of the inclusions and the diffusion of the carbon into the kamacite. 8 and 9 show a structure essentially like a sorbitic structure in artificial irons, as in heat-treated low-carbon martensite. 16 appears to be essentially a low-carbon martensite. 10 at high magnification shows spheroidize cementite (cohenite) similar to that produced by heat treatment of a low carbon martensitic steel. 17, 18, 19 show steadite bodies with a eutectiform structure; a few of these were found. Although we have a long start on this very interesting iron, a good deal remains to be done before it can be properly and thoroughly described. among the things to be done are: 1. An analysis of the iron itself. 2. Micro-chemical analysis to confirm beyond doubt the apparent steadite inclusions and the spheroidize carbide. 3. More photomicrographs, perhaps quite a good many of them. These photos were made by my assistant in Ann Arbor and I just told him to take whatever he thought was interesting. He certainly hit the high spots all right, but there are numerous small inclusions (steadite or perhaps cohenite) which ought to be taken at both low and high magnification; also plessite at high magnification to determine whether they have been altered by reheating (which presumably produced the streadite); groundmass kamacite at high magnificatino to determine the nature of heat alteration and the presence or absence of carbon, ect. I expect you will want to publish a thorough description of this important iron, and I should be glad to contribute the metallographic portion of it. I should not want to do so, however, without the further investigation referred to above. It will take some time, and also some money, perhaps $100 or $125 altogether for the lab, work at Ann Arbor is somewhat expensive. I am wondering whether you would be willing to give me a thin slice off the specimen. It is 7/6" thick on one side and 5/16" on the thinner side, so it ought to be possible to remove a very thin slice, which I could work on to advantage metallographically and which also would furnish material for analysis. The analysis is a "must", so the specimen will have to be cut somewhere and somehow, and the thin slice would seem to be the best procedure. I suppose you can easily do that with your own equipment. Kindly return the photos, as I have notations on the backs of some of them. Of course you will have a full set of all photos in due time With warm regards, Sincerely, (Stuart Perry - name is missing as this is the file copy.

[meteorite-list] Nininger to Perry Letter, Feb. 27, 1951
(American Meteorite Museum Letterhead) AMERICAN METEORITE MUSUEM OPPOSITE METEOR CRATER ON HIGHWAY 66 POST OFFICE BOX 1171 WINSLOW ARIZONA February 27, 1951 Dear Perry: Replying to your of February 19. I should be glad to comply with your second proviso, namely, that I furnish you with a slice of the 209 lb. meteorite in case we get only samples or none of the larger mass. In fact, I should have volunteered as much. But only on the condition that you bear, not half, but all of the expense. You see, as I figure it, our preliminary work of discovery together with the time I shall be obliged to spend, and the very considerable risk to health and limb are fully the equivalent of whatever cash outlay may have to be made on the project. The work in that bleakest of American deserts, in complete isolation from civilization, is going to be no picnic. Please accept this reply in the friendly spirit in which it is intended and do not feel under any pressure whatever to participate. We shall be able to handle it somehow. Cordially, (signed) H.H. Nininger HHN: AN

(Stuart Perry to Harvey Nininger letter, Perry's File copy) February 8, 1951 Dear Nininger: In this package I am sending you Herbenar's report on the iron granules, and the photos taken under his direction; also three or four earlier photos taken by my assistant at Ann arbor. I cannot add anything to Herbernar's report which is clear and thorough. The whole structure, including the presence of martensite, is consistent with the quick cooling of condensed drops of iron vapor. There is enough carbon in Canyon Diablo to account for martensite, and only a very small percentage of carbon and phosphorus would account for the Steadite - the Fe-Fe3C3Fe3P eutectic. If you use these data in a published paper, please give Herbenar all the credit, because I did nothing in the way of research. I want him also to look over the specimen from Peru and then I will send them to you, with the specimen. Cordially, (Stuart Perry - name is missing as this is the file copy. The original sent to Nininger would have been signed by Perry) The numbered photos were taken by Bidigare; the four lettered ones, A to D, by John F. Swing at the engineering laboratory at Ann Arbor.

(Stuart Perry to Harvey Nininger letter, Perry's File copy) February 19, 1951 Dear Nininger: I have your letter of February 16 and I am glad that you liked the pictures and report from Herbenar. I think his observations are wholly reliable. As to the Baja California iron, I am willing to go halves on the expense, but with one provise. If you should get only small samples of the big mass, or none at all, then I should like a substantial piece of your 209 pound mass. I hope this suggestion appeals to you favorably, and if so it is a deal. I should like nothing better than to go with you on the expedition, but unfortunately it is out of the question. I am so tied up with plans for our return, via San Francisco with a stop in California, that I can't make it. With best regards, Sincerely, (Stuart Perry - name is missing as this is the file copy.
