Re: [meteorite-list] 1099s coming?
Hi Richard, so you'll get a positive input from me: World will keep spinning around. Say I, from a country with a duestax yoke more than twice as heavy as in USA and with a Kafkaesque bureaucracy, the country with - lonely world record - with more than 70,000 single and different tax regulations. I don't know, in the countries I know there is a distinction between private sales and commercial sales regarding taxation. Hence between collectors sales and small (and normal) business sales. With different exemption levels. Little example, in Germany, there it is decisive for a sale reckoned among business (meteorite dealer) or private activity (meteorite collector): The intention to make a profit, the frequency a seller sells items, the time-span between a good was acquired and sold. Hence, if you throw here and there a meteorite into ebay, then it's a tax-free private sale, relatively independently from the result. As well if you sell your whole collection at once, which you have built up over the years or which you have found in your attic. On the other hand, if you set up every two weeks a meteorite on ebay or if you use the 1-AD-per-week-rule on the list; if you buy a meteorite on a show or from a dealer, planning to slice it and to sell some of the slices (and let it be only for refinance your collection) or if you buy a specimen to resell it the same year, then it is a business activity and the profit is added to your income, on which you have to pay your common taxes. (and if you have a turnover of more than 23.400$ meteorites sold per year, you have to pay value-add-tax on your sales if you have an annual profit of 31.400$, you have to pay also business tax). In Switzerland, I heard, it's easier, there you have simply a free allowance of a certain height, wherein you can declare sales of collectibles. On everything more, you have to pay tax. How the regulations are and whether there are similar distinctions in USA - I don't know them, but I'm curious. Does anyone know them? If yes, then I guess, that new regulation won't be that dramatic, but only a little inconvenience for the private ebay seller, to print out another sheet of paper, just like he prints the address label of the buyer. The professional seller however, is already documenting each of his sales, hence no change for him/her. Phony 250,000$ meteorites, Linton, I guess, won't disappear. Such meteorites become taxable only if they are really sold and not when they're offered. And honestly, when such a lunar or Martian with alien blood cells found in the backyard of the offerer ever was sold? Well, and in the end, I think it would be somewhat unfair, if your hot dog seller has to pay on each sold hot dog all the taxes, but a meteorite collector, who sells meteorites for generating money and profit none, wouldn't it?

Re: [meteorite-list] 1099s coming?
The new 1099 rules are not set to start until 2012 and before that the IRS still needs to issue its proposed regulations and hold public hearings. http://money.cnn.com/2010/05/05/smallbusiness/1099_health_care_tax_change/ So I agree with Susan; don't panic until we know what the rules are. Another interesting rule change which does go into effect this year is the 1099-K (which was part of the 2008 stimulus). Which affects merchants using paypal if they have more than $2 in payment AND have more than 200 transactions in a year. http://blog.auctionbytes.com/cgi-bin/blog/blog.pl?/pl/2010/9/1283997077.html - YvW On Sat, Jan 15, 2011 at 6:52 AM, batkol bat...@sbcglobal.net wrote: i believe the 1099 rule included in the new health care bill is already in the process of being revised.

[meteorite-list] Fwd: Re: New Paper About Kamil Crater, Egypt
-- Carl or Debbie Esparza Meteoritemax Paul, Thank you for this. I can't wait to read the full article. This confirmation of the age is interesting. Back on July 13, 2010 under the subject of Gebel Kamil Iron is official now I suspected that this fall was known to the Oxus Civilization. This because a very famous antiquity known as the scarfaces dated back to c. 2000 BC. has the same texture on it's skin as this meteorite material has. http://www.google.com/gwt/x?q=scareface+oxus+civilizationei=VN8xTZC4MZSQNoDP3M0Dved=0CA0QFjABhl=ensource=mrd=1u=http://www.louvre.fr/llv/oeuvres/detail_notice.jsp?CONTENT%253C%253Ecnt_id%3D10134198673225274%26CURRENT_LLV_NOTICE%253C%253Ecnt_id%3D10134198673225274%26FOLDER%253C%253Efolder_id%3D9852723696500803%26baseIndex%3D49%26bmLocale%3Den So, this fall being dated to 5 K Y old confirms the possibility that this may have been an observed fall. And may have hit and caused scars on some of the victims. Not only do these ancient figures display real meteoric iron but, they display the same texture as this unique and amazing Kamil irons do. And now the time of the fall coincides as well. Maybe this was an observed fall after all and maybe it did harm some folks? And these figures are proof of that event? And maybe the dubious find location of these great Scarfaces can finally be known?

[meteorite-list] Radar help
Hi, Is there a website to help understand how to interpret radar data for tracking meteorites? I've been reading the tutorials on the NOAA/NCDC toolkit site but it's geared more toward using the program and not actual interpretation of the data. It's more of an academic exercise at this point since I can barely walk let alone hunt meteorites in the field. :( Thanks, Rod __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] New Mexico Craters
Hi Abe, and List, For those interested, the website Abe mentioned is mine. It's at: http://craterhunter.wordpress.com/ I would be extremely interested in what you find at the crater sties in southeast New Mexico, and West Texas. Their numbers may seem to be extreme. But only from a 19th century uniformitarian-assumptive viewpoint that assumes that catastrophic impact events don't happen anymore. Or that, a typical extinction level, catastrophic impact event should consist of a single large bolide. And not a large cluster of smaller fragments. But look up in the sky, and take note of the kinds objects we typically see in the Taurid Complex, in short period, Earth-crossing, orbits. The Deep Impact mission to comet TEMPEL 1 showed the head of that comet to have the consistency of a dirty snow bank. It also showed that the object is a geologically active body. Comet HOLMES is unstable, and prone to violent outbursts. Images of fragmented comets LINEAR , and Scwassmann-Wachmann 3, both daughters of the Taurid Complex, make it abundantly clear that total, explosive, fragmentation of a comet from the Taurids can occur spontaneously at any time. And it can happen before it even gets close to a planet. So, in fact, a large cluster of smaller fragments is a far more likely catastrophic impact scenario than a single large bolide. Please read Paleolithic extinctions, and the Taurid Complex, by W. M Napier http://dl.dropbox.com/u/2268163/Paleolithic%20extinctions.pdf Professor Napier points out that the fragmentation of comets is now recognized as a common path to their destruction. He also states that, during the breakup of the Taurid progenitor, the Earth intersecting with the debris of that giant comet's breakup, and producing a mass extinction level catastrophe, is a reasonably probable event. He puts the the estimate at something like 1.1 billion tons of cometary debris impacting over the course of about an hour. The inventory of objects in the Taurid complex is data that's as empirical as anything you can dig up with a shovel, and a magnet. So, in fact, the pristine footprints of a very large, extinction level, super-cluster impact event of smaller fragments should be expected to be found somewhere in North America. The fragment sizes would have included stuff all the way down to dust grains. So it would be logical to predict that airburst phenomena played a very significant role. See: IMPACT MELT FORMATION BY LOW-ALTITUDE AIRBURST PROCESSES, EVIDENCE FROM SMALL TERRESTRIAL CRATERS AND NUMERICAL MODELING. H. E. Newsom1, and M. B. E. Boslough http://dl.dropbox.com/u/2268163/IMPACT%20MELT%20FORMATION%20BY%20LOW-ALTITUDE%20AIRBURST%20PROCESSES%2C.pdf There may be little, or no, shocked grains. But there should still be significant ET chemistry in any blast effected materials from the event. Would you be willing to send a few small rock specimens to Horton Newsom, at UNM's Meteoritics Lab.?

Hi List. Just a reminder my monthly updates for Cosmic Treasures Celestial Wonders http://www.ctreasurescwonders.com/index.html have been put up on my website. The A Flash from the Past Photo of the Month features the Tunguska Event of 1908. My slash (/) (\) photos of the month feature the Horse-head nebula in the constellation of Orion and the Aurora on the north and south poles of Jupiter. My Black Hole Mystery video of the Month is a fantastic short documentary of the 200 Mount Palomar Observatory with some vintage video! Worth looking at, since this telescope rewrote the books on astronomy and change the course of technology astronomy we have today. Thank you.

Re: [meteorite-list] Meteorites 101
Hi Walter and all, This may be the acceptable nomenclature METEOR (mt-r) 1. A bright trail or streak of light that appears in the night sky when a meteoroid enters the Earth's atmosphere. The friction with the air causes the rock to glow with heat. Also called shooting star. 2. A rocky body that produces such light. Most meteors burn up before reaching the Earth's surface. See Note at solar system. Usage The streaks of light we sometimes see in the night sky and call meteors were not identified as interplanetary rocks until the 19th century. Before then, the streaks of light were considered only one of a variety of atmospheric phenomena, all of which bore the name meteor. Rain was an aqueous meteor, winds and storms were airy meteors, and streaks of light in the sky were fiery meteors. This general use of meteor survives in our word meteorology, the study of the weather and atmospheric phenomena. Nowadays, astronomers use any of three words for rocks from interplanetary space, depending on their stage of descent to the Earth. A meteoroid is a rock in space that has the potential to collide with the Earth's atmosphere. Meteoroids range in size from a speck of dust to a chunk about 100 meters in diameter, though most are smaller than a pebble. When a meteoroid enters the atmosphere, it becomes a meteor. The light that it gives off when heated by friction with the atmosphere is also called a meteor. If the rock is not obliterated by the friction and lands on the ground, it is called a meteorite. For this term, scientists borrowed the -ite suffix used in the names of minerals like malachite and pyrite. The American Heritage® Science Dictionary Copyright © 2005 by Houghton Mifflin Company.

Re: [meteorite-list] Meteorites 101
Hello Count, Yes, many writers refer to the light phenomenon and the object itself as meteor but some make a distinction between the two. That definition does both, seemingly in the same breath! Also, does light originate from the glowing rock itself or the plasma (ionized gas) surrounding it?

Re: [meteorite-list] Meteorites 101
Most researchers I know consider the body to be a meteoroid while it is in its meteor phase. The term meteoroid is used to specifically identify the body, and distinguish it from the meteor effect. It is also common, and IMO correct, to talk of a meteorite before it hits the ground. Once the meteor phase has ended, surviving material will become meteorites, and may quite acceptably be called such (as in discussing the dark flight phase of a meteorite).

Re: [meteorite-list] Meteorites 101
Meteor, meteorite, and meteoioid: In response to the American Heritage® Science Dictionary Copyright © 2005 by Houghton Mifflin Company. Published by Houghton Mifflin Company, which is reported here to have stated that the object itself may be termed a meteor while in flight through the atmosphere, note that dictionaries are not the authoritative source for what an object is or is not. Dictionaries reflect only common (popular) usage, and if it is not a technical dictionary, more so. I remember being told as a student taking a graduate level course in the History and Development of the English language that dictionaries may be as much as 50 years behind the times in reflecting current usage. Within the informed scientific community, among those who are meteoriticists, a meteor refers to the light phenomena of the meteoroid while traversing through our atmosphere, and the object itself remains a meteoroid until it strikes the Earth or whatever other astronomical body it intercepts. Then it is referred to a meteorite. Note also the term micro-meteorites. Sometimes these terms are used incorrectly (and sloppily) in a popular, or non-technical sense, usually by the layman (or the news media). I don't think anyone has or will ever be burned at the stake for referring to a meteoroid as a meteor, unless they are of course one of my former students (joke)! But this is the way I have always seen these terms used when used correctly. This is the way I learned it as a student who received a degree in Astronomy from U.C.L.A. and who studied under one of the world's most respected meteoriticists, Dr. Frederick C.Leonard, who by the way was one of the founders of the Meteoritical Society. (Dr. Leonard was the first Editor of Meteoritics: the Journal of the Meteoritical Society. And, he was a perfectionist with the English Language.) I recall a number of discussions in class over these definitions, such as what would we call it if we were carrying a basket, and the meteoroid were to land in the basket, rather than hitting the Earth. Dr. Leonard, would it still be a meteoroid? (He would respond by clearing his throat with a faint growl, and ignore our question. But we knew he was fond of us!)

Re: [meteorite-list] Meteorites 101
Bolide is a term that it's good to avoid. It doesn't mean anything... or rather, it means too many different things. Fireball unambiguously means a meteor of a specific apparent brightness. Bolide is simply confusing. I usually think of a fireball as a meteor with a magnitude brighter than -3. I also sometimes think of a Bolide as being a fireball that has produced a sonic boom as well.

No. In fact, there is good evidence to suggest that the great majority of meteorites are produced by rather small meteors, which not only don't fragment, but aren't even fireballs. The sense that meteorites are the product of big, spectacular, fragmenting fireballs is produced because those are the only sorts of events where we can correlate the meteor and the meteorite.

[meteorite-list] Meteorites 101
The definitive source WIKIPEDIA!! Says; MeteoroidThe current official definition of a meteoroid from the International Astronomical Union is a solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom.[1][2] Beech and Steel, writing in Quarterly Journal of the Royal Astronomical Society, proposed a new definition where a meteoroid is between 100 µm and 10 m across.[3] The NEO definition includes larger objects, up to 50 m in diameter, in this category. Very small meteoroids are known as micrometeoroids (see also interplanetary dust). The composition of meteoroids can be determined as they pass through Earth's atmosphere from their trajectories and the light spectra of the resulting meteor. Their effects on radio signals also give information, especially useful for daytime meteors which are otherwise very difficult to observe. From these trajectory measurements, meteoroids have been found to have many different orbits, some clustering in streams (see Meteor showers) often associated with a parent comet, others apparently sporadic. Debris from meteoroid streams may eventually be scattered into other orbits. The light spectra, combined with trajectory and light curve measurements, have yielded various compositions and densities, ranging from fragile snowball-like objects with density about a quarter that of ice,[4] to nickel-iron rich dense rocks. Meteoroids travel around the Sun in a variety of orbits and at various velocities. The fastest ones move at about 26 miles per second (42 kilometers per second) through space in the vicinity of Earth's orbit. The Earth travels at about 18 miles per second (29 kilometers per second). Thus, when meteoroids meet the Earth's atmosphere head-on (which would only occur if the meteors were in a retrograde orbit), the combined speed may reach about 44 miles per second (71 kilometers per second). MeteorMeteor and Meteors redirect here. For other uses, see Meteor (disambiguation). See also Hydrometeor. Comet 17P/Holmes and GeminidA meteor is the visible path of a meteoroid that has entered the Earth's atmosphere. Meteors typically occur in the mesosphere, and most range in altitude from 75 km to 100 km.[5] Millions of meteors occur in the Earth's atmosphere every day. Most meteoroids that cause meteors are about the size of a pebble. They become visible between about 40 and 75 miles (65 and 120 kilometers) above the Earth. They disintegrate at altitudes of 30 to 60 miles (50 to 95 kilometers). Meteors have roughly a fifty percent chance of a daylight (or near daylight) collision with the Earth as the Earth orbits in the direction of roughly west at noon.[clarification needed] Most meteors are, however, observed at night as low light conditions allow fainter meteors to be observed. For bodies with a size scale larger than the atmospheric mean free path (10 cm to several metres)[clarification needed] the visibility is due to the atmospheric ram pressure (not friction) that heats the meteoroid so that it glows and creates a shining trail of gases and melted meteoroid particles. The gases include vaporized meteoroid material and atmospheric gases that heat up when the meteoroid passes through the atmosphere. Most meteors glow for about a second. A relatively small percentage of meteoroids hit the Earth's atmosphere and then pass out again: these are termed Earth-grazing fireballs (for example The Great Daylight 1972 Fireball). Meteors may occur in showers, which arise when the Earth passes through a trail of debris left by a comet, or as random or sporadic meteors, not associated with a specific single cause. A number of specific meteors have been observed, largely by members of the public and largely by accident, but with enough detail that orbits of the incoming meteors or meteorites have been calculated. All of them came from orbits from the vicinity of the asteroid belt.[6] FireballA fireball is a brighter-than-usual meteor. The International Astronomical Union defines a fireball as a meteor brighter than any of the planets (magnitude -4 or greater).[7] The International Meteor Organization (an amateur organization that studies meteors) has a more rigid definition. It defines a fireball as a meteor that would have a magnitude of -3 or brighter if seen at zenith. This definition corrects for the greater distance between an observer and a meteor near the horizon. For example, a meteor of magnitude -1 at 5 degrees above the horizon would be classified as a fireball because if the observer had been directly below the meteor it would have appeared as magnitude -6.[8] Bolide An especially bright meteor, a bolide (in astronomy)Bolide redirects here. For the Swedish guided missile BOLIDE, see RBS 70. In astronomy The word bolide comes from the Greek βολίς (bolis) which can mean a missile or to flash. The IAU has no official definition of

The Lerner-Trigg Encyclopedia of Physics, pg.1137 doesn't help much. The ONLY thing they have to say is; Meteorites, which occasionally fall to earth, are thought to be mostly fragments of asteroids scattered into earth-orbit crossing trajectories by gravitational resonance interactions, and pieces of comets on other debris moving through the vicinity of Earth. Analyses of meteorites have provided important clues about the formation and early history of the solar system. NOTHING about the distinction of the three differentiations of this thread.

Re: [meteorite-list] Meteorites 101
Most meteorites are single entities. They probably result from non-fragmenting events- just a piece of rock that enters slow and shallow, stops burning, and the core hits the ground. Meteorites that are grouped and found in strewn fields come from larger, fragmenting events. Meteorite hunters don't pay so much attention to small meteors because there's usually not enough information to use. Most are not caught on any instruments and result in few if any witnesses. And since they usually only produce a single, small fragment, the likelihood of recovery is smaller. Fragmenting fireballs and sonic booms are good indicators of meteorite production. But their absence does not suggest the absence of meteorites. Even if most meteorites follow small meteors, there is a clear, logical basis to only chasing the big fireballs. The meteor you refer to was not on my camera. The cameras closer to Denver haven't reported in yet- probably on Monday.

Re: [meteorite-list] Meteorites 101
Hello Stuart: We have had this conversation before. Your second question(when does an asteroid become a meteoroid): There is no real minimum asteroid size or maximum meteoroid size. When it comes up as a question, I usually say 5 or 10 meters is the crossover. Also, if an asteroid gets hit by something else, it will make lots of meteoroids! Your second question (when does a meteoroid become an asteroid): any small object that is not a comet (or man-made) when it has been observed and an orbit around the Sun is determined (even poorly) is an asteroid. The Minor Planet Center gives designations to asteroids (minor planets), not meteoroids. So, this could mean that an object only a few meters in diameter can be given asteroid status.

Re: [meteorite-list] Meteorites 101
Last statement on this topic (to avoid more crossing emails). The definition I have seen is that a fireball is defined as something brighter than Venus (so yes, about -4). Yes, the term bolide is generally avoided, but it is still used: People who study cratering events will use the terms impactor or bolide for the thing tghat makes the hole in the ground. This avoids having to deal with the object being a big meteoroid, an asteroid, or a comet. Larry Note, however, that the IAU defines fireball but is silent about bolide.

Re: [meteorite-list] Radar of Mississippi Fall?
I've added position and location of new video footage from Louisiana which was looking north. This new data matches up almost exactly to the trajectory I had already constructed. This just gives me more confidence in saying that the radar signature is from this meteor/fireball/bolide and that there are a few more rocks on the ground after this event. I hope this is helpful to people? I think its pretty interesting, in a day with this much technology... all the different ways of sensing this meteor. -Jake On Sat, Jan 15, 2011 at 4:19 PM, R.
