Re: [meteorite-list] LEONID'S MORE HOPE FOR COLLECTORS
Hi Rob, The key detail is that particles are essentially sorted according to their mass in to 'streams' - anything too big would presumably follow a different orbit to the smaller stuff. Hence most meteor shower particles are of a similar size (within reason). I think the sporadics are basically the bigger stuff all jumbled up...

They are minute fragments and burn completely in the atmosphere. Too bad the Media does not know that. Hmm. While most people with a background including astrophysics know this - of which I like to include myself as one - I have often wondered about the old meteorite/meteor shower conundrum I am pretty sure there are no meteorites which correspond date-wise to meteor showers but is this actually the case? While the average comet detritus is dust, it is not impossible, surely, for a much larger chunk to get ejected from a comet? The current theories of explosive outgassing would surely allow a chunk that broke off to achieve escape velocity. Is it beyond the realms of possibility that one of these may sit in the orbit of a comet waiting its transition into the atmosphere? I will confess, I have not the mathematical skill (primarily) nor time (secondarily) to work out the orbital dynamics of a big-enough chunk that broke off. I suspect that a large chunk is more likely to follow the orbital path of the main body than the dust which can get disperesed by radiation pressure quite quickly, though theres the radiative effect during rotation which effects orbits too (I forget its name). Will that cause it to move out of the comet's orbital path? We know comets fragment. We have photographic evidence of it. We know the fragments spread out (ditto). Why can we not have meteorites from comets? Just because we haven't yet, doesn't mean it is impossible. Mass extinctions have not been observed dur to major impact events yet, either. We all know that doesn't mean it can't happen or hasn't happened in the past. I am not sure my scenario is any different. That probe which crashed into the comet recently (again, I forget the name..I have a full time job to hold down), did it determine the consistency of the surface? Are comets and their fragments too fragile to survive the transition to Earth from space? If they are, then isn't it time we stopped likening Murchison to a comet? NOT SCIENTIFIC BIT. Or is it that we just don't know? That phrase which is likely to cause me to create the dead Scientists Society. A secret forum where top scientists can, in confidence, air their misgivings and failures in understanding which society will not let them admit. Funny, isn't it? As society dumbs down, it expects the egg-heads to know and solve more! Lazy bast**ds!

Re: [meteorite-list] Beauty and the Beast, Tulia (a) +/- Dimmitt
Hello Geoff, Mark, and all, I also discussed this topic with Art and thought I'd add a bit more to the story. Apparently on the initial Dimmitt stones that Oscar Monnig labeled, the two letters represented the initials of the person that he acquired the stone from. Obviously with so many Dimmitt stones coming in, this system soon became unworkable. He then went to an increasing letter system for the stones as they were acquired: A, B,C...Z, AA, ABAZ, BA, BBBZ...etc. I know that this system was also used for other meteorites as I have a Kendleton individual with both an early Monnig number and a Huss number.

Glen Huss and Margaret Nininger Huss cataloged the Monnig collection and painted those numbers onto the specimens. The lower number 12AV is a true original Oscar Monnig number, which predates the later Huss catalog. It is my understanding that the 12AV number was painted on by Oscar himself. As such, your specimen has a double Huss and Monnig provenance and is a fine and extremely collectible historic specimen. Congrats.

[meteorite-list] Mars Rover Snaps Panorama of Yawning Crater
http://space.newscientist.com/article/dn10596-mars-rover-snaps-panorama-of-yawning-crater.html Mars rover snaps panorama of yawning crater David Shiga New Scientist 16 November 2006 A new panorama of Mars's Victoria crater has been released in honour of the hardy rover Opportunity's 1000th sol, or Martian day, on the Red Planet. Meanwhile, Opportunity's twin, Spirit, has started moving again after seven months of being parked in the same spot. Opportunity, which celebrated its 1000th sol on Wednesday, took the panorama on 5 October from a perch on the Cape Verde promontory at the edge of the 800-metre-wide crater. Tracks in the Martian soil show the rover's path around Victoria's rim, and wind-sculpted sand dunes sit on the crater floor. The rover has since driven away from Cape Verde and is heading towards another promontory called Cape St. Mary. It will be looking for safe entry points into the crater along the way. On the other side of Mars, Spirit has finally started moving again after a long winter campout. Since April 2006, it has been parked on a rocky slope named Low Ridge Haven. Long hiatus During the long Martian winter, there was too little solar power for Spirit to drive around. So it has spent the time snapping pictures with its cameras and examining rocks and soil within reach of its instrument arm. But on 5 November it began to stir again, crawling over to some bright soil about 70 centimetres away that had been churned up by one of its wheels on its way to its winter resting spot. Examination with the rover's spectrometers over the past few days has confirmed mission scientists' suspicions that the material is rich in sulphates, says rover scientist Ray Arvidson of Washington University in St. Louis, US. This means it would have formed in the presence of water, he says. The tracks also contain some bluish material. There's an enormous amount of sulphur in the light material and we want to see if the blue material has sulphur in it too, Arvidson told New Scientist. Duty calls Both the sulphur and water may have come from eruptions of a suspected ancient volcano nearby, part of which is exposed in an outcrop called Home Plate, Arvidson says. In addition to their regular science activities, the rovers may be called on in the near future to help rescue NASA's orbiting Mars Global Surveyor. The 10-year-old orbiter has not been heard from since 5 November, after reporting difficulties in moving one of its solar arrays. The rovers may be asked to listen for a radio beacon on the wayward spacecraft, which MGS managers may try to turn on as a way of confirming that the orbiter is still alive (see Fleet of probes enlisted to contact silent Mars orbiter http://space.newscientist.com/article/dn10522-fleet-of-probes-enlisted-to-contact-silent-mars-orbiter.html). __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Deep Inside an Impact Crater Lake in Siberia
http://www.livescience.com/imageoftheday/siod_061117.html Deep Inside a Lake LiveScience.com November 17, 2006 A team of scientists will embark on an expedition to a polar lake in Siberia, which should yield data that will provide the most detailed record of past Arctic climate to date. Understanding the natural climatic variations of the Arctic - such as which aspects are cyclic and which are stable - will illuminate how the region evolved from a warm ecosystem blanketed in forest to a cold one covered in permafrost. And ultimately it could give scientists a glimpse at the Arctic of tomorrow, the researchers say. The destination is Lake El'gygytgyn, a lake of roughly nine miles across that was formed when a meteorite hurtled into northeastern Siberia around 3.6 million years ago. Unlike much of the Arctic, this lake was never covered by glaciers or ice sheets and thus has received a steady accumulation of sediment since the time of impact. Scientists will collect deep cores of this sediment - cylindrical columns of dense muck that should provide a detailed narrative of the past climate of the Arctic. Once the cores are extracted, the assemblage of pollen grains, algae and bacteria within the sediment will tell the scientists what was living in and around the lake throughout its history. The researchers will also read the cores for changes in geochemistry, the magnetic orientation of the muck's minerals and other parameters that capture what happened to the Arctic's climate since the time of impact. These data will be compared with cores taken from the north Atlantic and Pacific oceans, as well as tropical oceans, allowing scientists to address climate change questions on a broad scale. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Anybody care to back me up on this? Statistically I'm sure you're right, so I'll back you up. If you run into a uniform wind in your face when it is raining you get wetter and pelted harder than if you run away... If we say everything solar is traveling around with similar orders of velocity as earth in its orbit (66,000 miles per hour - over 100,000 km/hour) this is true. Of course if Earth's velocity were negligable it wouldn't matter. That's the difference with bugs which can't catch up to me and still have enough flight enery to squash themselves on my rear windshield when I drive , but meteoroids do catch up to the earth with probability of some trigonometric function, calculated with relative speeds and radiants...depending on the time of day. I have consistently whipped meteoroids and they are too afraid to respond to my dares, as well as bugs, catching up, driving during the day - but it remains to be seen if meteoroids can catch up. Maybe I'll give them a handicap, drive east at about 10PM at low latitude, and then check my radiator grill for chondrules and inclusions... Which brings up the other factor when observing meteors and which also comes into play for bolide production and meteorites. At the Vernal Equinox (the first day of Spring), an observer north of the tropics see the least because the windshield tilt adds to the angle, but on the first day of Autumn (Autumnal Equinox) in the north, (s)he see the most meteors because the windshieldis tilted the least as we plow through our orbit. A true, efficient meteor hunter could always get a front seat if needed. This happens because earth is tilted. So if you want to increase odds, consider the benefits and drawbacks to work around Sept. 22, after midnight:-) Actually the windshield of our great blue spaceship is the atmosphere, and the the interstate highway out here follows a feeder ring outside of downtown business end of the Solar System where people would be fried to a crisp. The route the spaceship follows could be called Apex route since it follows the apex vector - the point connecting the center of the Earth with the most forward point in the orbit which changes every instant during rotation and revolution!

Re: [meteorite-list] Meteor showers and meteorite falls
At 1 AU, objects in orbit around the Sun have similar orbital speeds (not velocities). At sunset, the zenith (approximately, depending on latitude) is pointing back along the Earth's orbital path, so objects coming from that direction are in prograde orbits. As such, they have low relative speeds compared with the Earth- playing catch up, as you say. At dawn, the zenith is pointing forward along the Earth's orbital path, so we tend to get hit by objects in retrograde orbits, with a consequent high relative speed. I don't know the statistics for the time distribution of witnessed falls, and they would probably be distorted by the fact that there are more hours of wake time between sunset and midnight then between midnight and dawn. I do know from years of allsky camera data that the sort of slow, bright meteors that are likely to produce meteorites occur several times more frequently before midnight than after.

I have 8 DIFFERENT hammers from Park Forest and have utilized the following format for all my hammers, which I find quite adequate: While I do not provide ALL the information (see the bluebook), for all my hammers I have gone to a standardized format depending upon size: - for the 2 X 2 macromount boxes (and the larger pieces) I print on card stock with name, date of fall and item struck on the front. On the back, I include additional information, such as type, weight of the specimen, etc. Though a macromount or riker box will protect a label on standard thickness paper, card stock just looks nicer to me. - for very small specimens I use the membrane boxes and print the information on standard paper, then use a paper cutter to cut the paper the proper width and length, then tape it around the side of the membrane box once the specimen is inserted. In most cases, I had write the weight of the specimen on this label unless it is a true Bessey Speck, in which case, the specimen is in a gelatin capsule before placing in the membrane box, as such tiny specimens will not be gripped by the membrane within the box and tend to wander off to the edge of the display box. I took a few photos to demonstrate this and they can be seen at: http://community.webshots.com/album/555663888rIOxSu Originally, I was doing all the labels by hand, but decided this looked far nicer, even though it lost a bit of the personal touch. Every dealer does it differently and that is one of the aspects I don't think collectors can ever expect to change. I don't see why everyone doesn't make their own labels and save the dealer labels separately (in alphabetical order for easy retrieval) and then their entire collection would have consistent labels - I have seen many collections (other than my own) that do this and it is quite a bit more attractive than a myriad of different shapes, sizes and colors of cards from the dealers from whom the piece was acquired.

Re: [meteorite-list] Meteor showers and meteorite falls
The range of speeds for incoming meteoroids is 12-72km/s. 12 being the escape velocity at the earth. Any object moving with the earths speed and in the same direction, if it were to collide with the earth would fall at this speed. Any object travelling slower than the earth will only hit the leading side at 12km/s plus the difference in orbital speed. Particles travelling faster than the earth can hit either side with 12+earths orbital speed + initial orbital velocity. This initial orbital velocity can be anything up to the escape velocity fr the suns gravity. I forget the earths orbital speed but the max speed available is 72km/s and I undertand the leonids have about this. This is consistent with a high velocity trail coming at us head on which explains the sharp peak on the leading side of the earth. The upshot of all this is that (like the car window collecting randomly moving bugs), the earth collects more detritus on it's leading side, so any random meteor is more likely to be seen after Midnight local time and I suppose, you ought to see big fireballs more frequently in the early morning too (by which I mean daylight) Whether this leads to more recovered falls I couldn't guess at. The requirements for recovery being quite a narrow window of parameters, the high speed of those hitting head on is likely to render them vapour well before they become -ites. But I cannot be definitive on this. It is worth pointing out that while planets and (generally) asteroids, all follow the same orbital direction around the sun, comets can perform their orbits from any direction. High above or below the ecliptic and with or against the normal planetary direction. This is why it is possible to have such a large range of incoming speeds but it'll be comet fragments which occupy the higher ranges only.

And the most likely time for a retrivable fall is 4:00 pm when a meteorite is approaching earth is catching up to it in orbit. Kind of like retriving bugs off the front and back windshields. Anybody care to back me up on this? Statistically I'm sure you're right, so I'll back you up. If you run into a uniform wind in your face when it is raining you get wetter and pelted harder than if you run away... If we say everything solar is traveling around with similar orders of velocity as earth in its orbit (66,000 miles per hour - over 100,000 km/hour) this is true. Of course if Earth's velocity were negligable it wouldn't matter. That's the difference with bugs which can't catch up to me and still have enough flight enery to squash themselves on my rear windshield when I drive , but meteoroids do catch up to the earth with probability of some trigonometric function, calculated with relative speeds and radiants...depending on the time of day. I have consistently whipped meteoroids and they are too afraid to respond to my dares, as well as bugs, catching up, driving during the day - but it remains to be seen if meteoroids can catch up. Maybe I'll give them a handicap, drive east at about 10PM at low latitude, and then check my radiator grill for chondrules and inclusions... Which brings up the other factor when observing meteors and which also comes into play for bolide production and meteorites. At the Vernal Equinox (the first day of Spring), an observer north of the tropics see the least because the windshield tilt adds to the angle, but on the first day of Autumn (Autumnal Equinox) in the north, (s)he see the most meteors because the windshieldis tilted the least as we plow through our orbit. A true, efficient meteor hunter could always get a front seat if needed. This happens because earth is tilted. So if you want to increase odds, consider the benefits and drawbacks to work around Sept. 22, after midnight:-) Actually the windshield of our great blue spaceship is the atmosphere, and the the interstate highway out here follows a feeder ring outside of downtown business end of the Solar System where people would be fried to a crisp. The route the spaceship follows could be called Apex route since it follows the apex vector - the point connecting the center of the Earth with the most forward point in the orbit which changes every instant during rotation and revolution!

[meteorite-list] Meteorites and Their Parent Planets Companion (?)
Hello list, Meteorites and Their Parent Planets by Harry Y. McSween, Jr., printed by the Cambridge Press should be a part of meteorite book library. It has been a favorite of list members for several years now. Soon, the Cambridge Press will come out with what you might consider a companion book. Meteor Showers and Their Parent Comets by Peter Jenniskens. The Cambridge Press has a history of high quality science publications, including Richard Nortons The Cambridge Encyclopedia of Meteorites. (Which isnt really an Encyclopedia .but is a must have), so I am sure Meteor Showers and Their Parent Comets will be a great read/reference tool.

This blog is part of blogger.com, and the e-mail address that is bouncing our messages from time to time is [EMAIL PROTECTED] Yes, but that looks to be an address for a sevice on blogger.com, not a user... Correct. It just showed me what service the blog was associated with, not the blog or the blogmaster. Blogger.com, owned by Google, has search capibilities, and searching meteorite-list only gives a few valid options. The blog I posted seemed the logical choice. Note the date of the first post is about the time we started getting the bouncing. I will also note it appears the blogmaster turned off automatic updating postings on the page, which I imagine is a simple option. If it was made for adminstration use then there would be no need to update it to the public, if it updates on his end, without publishing. With the messages in that format, one could scroll the whole day pretty fast. Of course I could be wrongbut it seems logical to me...:^) Clear Skies, Mark __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
