Re: [meteorite-list] AD: ebay auctions ending in 24 hours
Hi Michael, List, Sorry for the late reply. Just got home. The specimen has not been coated or altered in any other way. It is as found. The feature you describe as glossy is merely a light reflection in the specimens crust. I am using a very powerful light so that might be the reason the crust seems a little bit glossy. The pictures have only been white adjusted in photoshop. I hope I could answer the question.

[meteorite-list] A Lorton thought....
Hi Listees and Hunters, Although I was born up north and walked to school in the snow, we moved down south when I was a grade-schooler. So forgive me if my knowledge of snow-related things is lacking. What happens to the snow that the city/county snowplows move? Is it possible that some Lorton meteorites may have been buried under the subsequent snow, and ended up being snowplowed down the street into a big pile somewhere and dumped. Is there some kind of routine for disposing of this material? If so, where does it go? Is there some centralized dumping ground that may have meteorites buried in it?

Re: [meteorite-list] A Lorton thought....
Hi Mike, I live in the area, so I'll try to take a stab at answering... Snow plowed from the streets and most lots was generally plowed off to the side of the road or lot where it eventually melted. I should have taken a picture of the pile that was in the Pentagon lot... it was there last weekend still, but this weekend (after several very nice days) it is gone... The snow piles that were dumped over the edge of the parking garage at campus were still there (they are on the north side of the building)... Some parking lots but mainly garages that couldn't plow snow to the side would have it transported... not sure where though. I'm sure that around Lorton, the neighborhood streets were plowed but the snow left in huge drifts on the side of the road and on property Clear Skies!

[meteorite-list] AD:Almahata Sitta 2008 TC3 for sale on eBay
Hello Listers, I would like to offer another Almahata Sitta micro thats is bigger in size on eBay for those who collect on a micro level. This is a perfect opportunity to add this to your collection before Almahata Sitta is not available at reasonable prices. For those that haven't heard about Almahata Sitta here is an intro what you will find on my auction on eBay Up for auction is a micro Almahata Sitta meteorite (2008 TC3) which fell on 7 October 2008, 05:46 h local time (UT+3) in Nahr an Nil, Nubian Desert, Sudan. Almahata Sitta classification is Ureilite, polymict, anomalous. Here is a chance to own the many firsts that Alamahata Sitta has set in meteorite history. The current market value is around $1500 a gram and here is a chance to own a micro at a fraction of the cost before it sold out. Here is a video link about Almahata Sitta meteorite (2008 TC3)... http://www.youtube.com/watch?v=UoZ1WK7_L7c What makes Almahata Sitta meteorite so special is that on October 6, 2008, a small asteroid called 2008 TC3 was discovered by the automated Catalina Sky Survey 1.5 m telescope at Mount Lemmon, Tucson, Arizona, and found to be on a collision course with Earth. This is the first time scientists were able to observer the course of a meteorite fall from space before it ending its journey in the Sudan Desert. What also makes this Almahatta Sitta even more unique is that it’s the first Ureilite meteorite to have traces of amino acids which scientist believe could have jump started life on Earth.

I'm not a director, but I could see where if they had led into the program with the guys turning up the scrap and then the comedic relief provided by finding of that railroad gandy dancer's hammer (Nice piece incidentally..probably around 100 years old. Genuine antique.) And then Shauna hitting it big with the siderite it would have held it's own on a big time channel.

[meteorite-list] AD:Almahata Sitta 2008 TC3 for sale on eBay
Hi Richard and List, That's is a great point that you brought up about the automated Catalina Sky Survey 1.5 m telescope at Mount Lemmon, Tucson, Arizona, and how Catalina is not an automated survey. I wonder why they say that about her? Is it the software that is used for Catalina or the way she scans the sky making it automated? Or is it all done manually these days and one by one scientist scan the sky asteroids? Here is an article from 2009 that uses automated when referring to Catalina Sky Survey The four-meter-diameter asteroid, called 2008 TC3, was initially sighted by the automated Catalina Sky Survey telescope at Mount Lemmon, Ariz., on Oct. 6. Numerous observatories, alerted to the invader, then imaged the object. Computations correctly predicted impact would occur 19 hours after discovery in the Nubian Desert of northern Sudan. http://esciencenews.com/articles/2009/03/25/asteroid.monitored.outer.space.ground.impact Shawn Alan [meteorite-list] AD:Almahata Sitta 2008 TC3 for sale on eBay Richard Kowalski kowalski at lpl.arizona.edu Sun Mar 28 19:17:33 EDT 2010 Previous message: [meteorite-list] Adventures in Prospecting: Iron From the Sky Next message: [meteorite-list] AD:Almahata Sitta 2008 TC3 for sale on eBay Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] --- On Sun, 3/28/10, Shawn Alan wrote: ... > discovered by the automated Catalina Sky Survey 1.5 m > telescope at Mount Lemmon, Tucson, Arizona, ...

For some reason this misrepresentation continues to be used in papers in which he is listed as a co-author. Sorry if this seems to be picking nits, but our observers work very hard and we feel that a primary reason we are so productive is because we are NOT automated.

This is a perfect opportunity to add this to your collection before Almahata Sitta is not available at reasonable prices. For those that haven't heard about Almahata Sitta here is an intro what you will find on my auction on eBay Up for auction is a micro Almahata Sitta meteorite (2008 TC3) which fell on 7 October 2008, 05:46 h local time (UT+3) in Nahr an Nil, Nubian Desert, Sudan. Almahata Sitta classification is Ureilite, polymict, anomalous. Here is a chance to own the many firsts that Alamahata Sitta has set in meteorite history. The current market value is around $1500 a gram and here is a chance to own a micro at a fraction of the cost before it sold out. Here is a video link about Almahata Sitta meteorite (2008 TC3)... http://www.youtube.com/watch?v=UoZ1WK7_L7c What makes Almahata Sitta meteorite so special is that on October 6, 2008, a small asteroid called 2008 TC3 was discovered by the automated Catalina Sky Survey 1.5 m telescope at Mount Lemmon, Tucson, Arizona, and found to be on a collision course with Earth.

Re: [meteorite-list] On Now! - Sodom & Gomorrah on Science Channel
Don't know, they were supposed to be parts of the asteroid. But maybe they were flaming bits of terrestrial material blasted up into the atmosphere by the explosion. Maybe it was the imagination of a good 3D animation artist. I'm not saying it's correct. They compared Tunguska to this event and there's a general consensus that that event dropped no meteorites that we know of. Of course the celestial body that caused the Tunguska event wasn't near a mile wide either. Who knows? but it may be plausible IF their theory is correct about them finding the cities of Sodom and Gomorrah earlier in the show. Has the cities been found? Supposedly the mass grave they found on the outskirts of the small town is evidence of it. I think the number of dead in the area was 20,000?

Re: [meteorite-list] Catalina Sky Survey
All, I've changed the subject line to bring it in line with the discussion. As I started writing this, I thought I could get by with a simple response, but to give a clear idea of why Catalina is not an automated system, I thought I'd give you all a more detailed look at what we do each night. Sorry for the length of this response... Shawn I'll answer your query about the article first. That article is one of a line of articles all based on Jenniskens' initial and continuing misrepresentation of how we operate. I can't blame the reporters because they can only go on what they are told. "Automated" has been repeated often enough that it is becoming accepted fact. At Catalina the observer chooses the fields that will be observed and in what order, making this decision depending on the conditions, previous coverage, needs of follow up observations, etc. The telescope then observes those fields in order. Once this first set of fields has been completed, the telescope repeats the cycle three more times. Each time an image comes down from the camera our computers process the images, and then record in x-y coordinates every "object" it sees. Once all four images have been made and processed the four sets of x-y coordinates are compared with each other. The objects that are in the same locations are stars, since they haven't moved. They are ignored. Then a number of filters are run to remove groups of false detections around bright stars and "objects" that appear to be moving too fast (artificial satellites) or too slow. At the beginning of the night we download the file of the known 300,000+ minor planets from the Minor Planet Center. Our software uses this file to calculate what object should have the same position and apparent motion as the remaining suspects that are left after these filtering steps. These, along with the remaining candidates that can't be identified are are given one final calculation before the are presented to the observer for validation as an actual or false detection. This calculation assigns a number called the "Digest". The Digest is a determination that the apparent motion of the object is that of a Main Belt asteroid or not. Objects that are identified are presented at the bottom of our validation candidates. Those that have low digest numbers, representing objects that have apparent motion indicative of Main Belters, but which have not been identified, are presented in a group second from the bottom. Finally, objects which have higher digests, meaning they are not Main Belters, are presented at the top. The observer has to go through and actually look at each and every one of the candidates in this first group of detections. This could number from just a couple to 100 or more. Most of these will be marked "N" for "No" they are not real, but every so often an object is presented to the observer for validation that is real and clearly has a motion that is not typical of a main belt asteroid. Of these four observations, sometimes one or more detections may be "bad". In that case the observer can accept all four, or throw out one, two or all four observations. (You never submit a single observation). The observer also can manually measure each position to increase the accuracy of the positions. After a real object is discovered, the observer then compares the position of all known Near Earth Asteroids with the position and motion of this object to determine if it is known or not. Sometimes it is but anywhere from 1 to 10 or more times a night it is a newly discovered NEO. The observer then reports the observations to the Minor Planet Center, which posts these observations in near real time. The observer also schedules additional same night follow up observations before continuing the search for more new NEOs. We repeat this process for anywhere from 9 to 20 fields per set and up to 20 or so sets in a single night. As you can see this means we look at thousands of NEO candidates each and every night. Part of our success is we operate at a detection sigma of 1.2. Most consider a sigma of 3 a minimum to provide a reasonable Signal to Noise Ratio, but we have determined that the human eye - brain system can pull out real objects that are barely detectable above the noise level. True automated surveys don't go below 5 sigma because you can't teach a computer and software to reject false positives at such a low SNR. So, to summarize. A human determines where to observe each night, all night A human looks at each and every candidate to determine if it is real or not A human determines if all the positions are accurate or need to be remeasured. A human determines in real time if a real candidate is known or not. A human submits the observations for public dissemination in real time. A human determines if same night follow up observations need to be scheduled and accomplished. A human determines if the expected plan of observations can be followed or needs to be modified becau

Re: [meteorite-list] Catalina Sky Survey
Shawn. No I don't think that. I believe it came from this paper: http://asima.seti.org/2008TC3/nature07920.pdf And this citation when the meteorite was named: http://tin.er.usgs.gov/meteor/metbull.php?code=48915 and the fact that in continuing papers it has not been corrected. LINEAR is an automated system. PAN-STARRS will be an automated system. While the data reduction is automatic, the actual operation at Catalina relies on the human observer being in control in real time, making decisions. The images you cite are the CSS discovery images.

Now if your a seller and offering an item that isn't that much I could see the seller charging $15 to $40 for shipping and handling/packaging quote un quote, if they know the item will go for that rate at buy it now or 5 day auction bid, where it would only go for $2 to $5 at closing, which the seller would only be charged for the closing cost and not the shipping and handling cost (that was a long run on sentence).

Most of these will be marked "N" for "No" they are not real, but every so often an object is presented to the observer for validation that is real and clearly has a motion that is not typical of a main belt asteroid. Of these four observations, sometimes one or more detections may be "bad". In that case the observer can accept all four, or throw out one, two or all four observations. (You never submit a single observation). The observer also can manually measure each position to increase the accuracy of the positions. After a real object is discovered, the observer then compares the position of all known Near Earth Asteroids with the position and motion of this object to determine if it is known or not. Sometimes it is but anywhere from 1 to 10 or more times a night it is a newly discovered NEO. The observer then reports the observations to the Minor Planet Center, which posts these observations in near real time. The observer also schedules additional same night follow up observations before continuing the search for more new NEOs. We repeat this process for anywhere from 9 to 20 fields per set and up to 20 or so sets in a single night. As you can see this means we look at thousands of NEO candidates each and every night. Part of our success is we operate at a detection sigma of 1.2. Most consider a sigma of 3 a minimum to provide a reasonable Signal to Noise Ratio, but we have determined that the human eye - brain system can pull out real objects that are b
[meteorite-list] Silicated Iron vs. Winonaite
G'day List, I have a question I'm hoping someone may be able to answer as I don't know if I have this right. My (basic) understanding is that the silicate parts of a silicated iron are actually Winonaite material. When this silicate material is found without iron, then they are classified as a Winonaite but with/in an iron then they become a silicated iron. Is this right or am I way off here? There seem to be an increasing amount of silicated irons being classified as a Winonaite. So when is a silicated iron not a Winonaite and vice-versa?
