[meteorite-list] Tucson Gem, Mineral & Fossil Showcase POI file useful?
Hello again all. I noticed that a number of people downloaded (and hopefully used) my Tucson Gem, Mineral & Fossil Showcase Point of Interest file for the Tucson Shows this year. It can be found on the POI Factory site here: http://www.poi-factory.com/node/24678 Personally I was happier with the way the file worked when I was traveling around town this year than I was last year. I live here and found having it installed rather useful to me. I'm curious if others found it useful too? Now that the shows have ended, I'd be very interested to hear feedback from any and all of you who downloaded and used the file. What did you like about it? What did you dislike about it? Was anything missing, misplaced or plain wrong? Are there any additions or improvements you'd like to see for next year's version?

[meteorite-list] I Love Comets
Flyby Time. Happy Valentine NExT http://www.jpl.nasa.gov/news/news.cfm?release=2011-050&cid=release_2011-050&msource=11050&tr=y&auid=7771872 --- NASA Spacecraft Hours From Comet Encounter February 14, 2011 Stardust-Next Mission Status PASADENA, Calif. -- As of today, Feb. 14, at 9:21 a.m. PST (12:21 p.m. EST), NASA's Stardust-NExT mission spacecraft is within a quarter-million miles (402,336 kilometers) of its quarry, comet Tempel 1, which it will fly by tonight. The spacecraft is cutting the distance with the comet at a rate of about 10.9 kilometers per second (6.77 miles per second or 24,000 mph). The flyby of Tempel 1 will give scientists an opportunity to look for changes on the comet's surface since it was visited by NASA's Deep Impact spacecraft in July 2005. Since then, Tempel 1 has completed one orbit of the sun, and scientists are looking forward to discovering any differences in the comet. The closest approach is expected tonight at approximately 8:40 p.m. PST (11:40 p.m. EST). During the encounter phase, the spacecraft will carry out many important milestones in short order and automatically, as the spacecraft is too far away to receive timely updates from Earth. These milestones include turning the spacecraft to point its protective shields between it and the anticipated direction from which cometary particles would approach. Another milestone will occur at about four minutes to closest approach, when the spacecraft will begin science imaging of the comet's nucleus. The nominal imaging sequence will run for about eight minutes. The spacecraft's onboard memory is limited to 72 high-resolution images, so the imaging will be most closely spaced around the time of closest approach for best-resolution coverage of Tempel 1's nucleus. At the time of closest encounter, the spacecraft is expected to be approximately 200 kilometers (124 miles) from the comet's nucleus. The mission team expects to begin receiving images on the ground starting at around midnight PST (3 a.m. on Feb. 15 EST). Transmission of each image will take about 15 minutes. It will take about 10 hours to complete the transmission of all images and science data aboard the spacecraft. Live coverage on NASA TV and via the Internet begins at 8:30 p.m. PST (11:30 p.m. EST) from mission control at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Coverage also will include segments from the Lockheed Martin Space System's mission support area in Denver. A post-flyby news conference is planned on Feb. 15 at 10 a.m. PST (1 p.m. EST). For NASA TV streaming video, scheduling and downlink information, visit: http://www.nasa.gov/ntv . The live coverage and news conference will also be carried on one of JPL's Ustream channels. During events, viewers can take part in a real-time chat and submit questions to the Stardust-NExT team at: http://www.ustream.tv/user/NASAJPL2 . During its 12 years in space, Stardust became the first spacecraft to collect samples of a comet (Wild 2 in 2004), which were delivered to Earth in 2006 for study. The Stardust-NExT mission is managed by JPL for NASA's Science Mission Directorate in Washington. Lockheed Martin Space Systems in Denver built the spacecraft and manages day-to-day mission operations. A press kit and other detailed information about Stardust-NExT is online at: http://stardustnext.jpl.nasa.gov . - Regards, Eric __ 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] Possible Meteorite Spotted Over Philly
http://www.myfoxphilly.com/dpp/news/local_news/021411-possible-meteorite-spotted-over-philadelphia Possible Meteorite Spotted Over Philly Fox 29 has received several reports of an object that resembled a meteor that has spotted in the sky near the Philadelphia Navy Yard facility. The incident happened before 12:45 p.m. ET, according to witnesses who called Fox 29. There are also reports on Twitter and Facebook about the incident. Fox 29 TV reporter Chris O'Connell also saw the object, which he described as "majestic" and "beautiful," at about 12:35 p.m. as he was driving on I-95 near the airport. A Fox 29 viewer spotted the object at 12:36 p.m. in Delaware. There also have been several reports of similar occurrences today in Connecticut and New York. Meteorites are naturally occurring objects that originate in space and survive a fall through Earth's atmosphere. Most are remnants of asteroids or possibly comets. The Navy Yard facility is on the Delaware River, which is also used as a flight path to Philadelphia International Airport. The American Meteor Society track meteorite spottings but has not yet posted anything today in its Web site.

Thanks for sending this out Phil. There have been over 20 reports to the AMS in the last hour about this. That is a lot of reports in a short amount of time for a night time fireball, so it must have been pretty significant.

Re: [meteorite-list] Yet another PA fireball
Thanks Rob. I did mean night time, but what I meant is: 20 reports in 1 hour is a lot for a night time fireball, (so considering this was a daytime fireball that is REALLY ALOT).

[meteorite-list] Help "Self Classify & Pair" my new stone
I picked up a small 37.225g half cut stony from Blaine. It looks pretty fresh to me and I have a general idea of the class it may be, but... I'd be interested in all of you experts taking a look and letting me know your thoughts on its classification and suggestions on what other stones it looks like. I'm not going to use these opinions to actually self pair or classify the stone. I'm just curious to hear what others think it may be and nothing more.

[meteorite-list] The Two Faces of Tempel 1
http://www.jpl.nasa.gov/news/news.cfm?release=2011-051 The Two Faces of Tempel 1 Jet Propulsion Laboratory February 14, 2011 Just one year before its Feb. 14 encounter with comet Tempel 1, NASA's Stardust spacecraft performed the largest rocket burn of its extended life. With the spacecraft on the opposite side of the solar system and beyond the orbit of Mars, the comet hunter's rockets fired for 22 minutes and 53 seconds, changing the spacecraft's speed by 24 meters per second (54 mph). The burn was a result of an international effort to determine something that could very well be indeterminate -- which face of Tempel 1 will be facing the sun when Stardust hurtles by tonight, Feb. 14, the evening of Valentine's Day in the United States. "Our goal is to re-visit a comet to look for changes that occurred since NASA's Deep Impact mission took a look five-and-a-half years ago," said Tim Larson, Stardust-NExT project manager from NASA's Jet Propulsion Laboratory in Pasadena, Calif. "We may also see the crater that Deep Impact created in 2005, but because of Tempel 1's rotation, there is no guarantee. At the end of the day, whatever we see there should provide some great new science." While comets have been observed and postulated on for centuries, cometary science acquired literally "on the fly" is a relatively new field. Since 1984, there have been spacecraft flybys of six comets. Of these, none involved the ability to look for changes that may have occurred as a result of the comet's orbit around the sun. That is, until Stardust-NExT and Tempel 1 meet tonight. "You could argue that comet Tempel 1 is the most unique icy dirtball in our solar system," said Joe Veverka, Stardust-NExT principal investigator from Cornell University, Ithaca, N.Y. "Not only does it have many intriguing physical characteristics that fascinate the scientific community, it also has been analyzed and scrutinized time and again from the ground and space." In January 2007, NASA chose Veverka's plan to revisit comet Tempel 1 with NASA's already in-flight Stardust spacecraft. Stardust had just completed the mission it was designed for - flying to comet Wild 2, collecting samples of the coma as it hurtled by, and then flying back to Earth to drop off a sample return capsule so scientists could study pieces of comet in their labs. Ask any spacecraft project manager -- re-tasking a spacecraft designed for a completely different mission is a challenge. To be in the right place at the right time to see changes in surface features on a small celestial body that seemingly changes its rotation rate on a whim and is out of view from observers for most of its five-and-a-half-year orbit about the sun -- that's something else entirely. But that was the assignment given to Stardust-NExT team members Mike Belton, Steve Chesley and Karen Meech. "As comets sweep though the inner solar system, they come alive," said Belton, a Stardust-NExT co-investigator from Belton Space Initiatives in Tucson, Ariz. "They belch gas and dust, and this outgassing can not only change their orbits, it can also change their rotation rate." Determining the comet's rotation rate and which side will be illuminated when is tricky, because the comet had only been seen up close for a short time in July 2005 during the Deep Impact encounter. From then on, the comet nucleus, about 6 kilometers (3.7 miles) wide, appeared to observers to be little more than a point of light in the sky for even the best telescopes -- including NASA's Hubble Space Telescope. (Tempel 1's orbit takes it as far out as Jupiter's orbit and almost as close as Marsâ orbit.) But even points of light can bear scientific fruit for astronomers and space scientists. The flattened, oblong Tempel 1 nucleus was no exception. "Its shape is central to what we could learn about its rotation," said Belton. "A comet reflects the sun's light. When one of its two broad regions is facing us, it gives off more light. When one of its skinnier sides is pointed toward the telescope, it gives off less light. So we felt we could develop an accurate model for the comet's rotation." The plan was for Belton and Chesley to generate comet rotation models independently. What both needed was data (and a lot of it) on the amount of sunlight Tempel reflected and when. Both knew the source for that information: fellow Stardust-NExT co-investigator Karen Meech. Meech, an astronomer from the University of Hawaii, reached out to her network of fellow astronomers around the world. "They came through (in spades)," said Meech. "In total, 25 telescopes at 14 observatories around the world allocated about 450 whole or partial nights to this project. With telescope time at a premium, it was a massive effort on their parts." With the Tempel 1 light curve data acquired by Meech in hand, Belton and Chesley independently worked on determining the rotation rate for Tempel 1. As it turned out, the data revealed it was not so easy. "T
[meteorite-list] Stardust-NExT Spacecraft Hours From Comet Encounter
http://www.jpl.nasa.gov/news/news.cfm?release=2011-050 NASA Spacecraft Hours From Comet Encounter Jet Propulsion Laboratory February 14, 2011 Stardust-Next Mission Status PASADENA, Calif. -- As of today, Feb. 14, at 9:21 a.m. PST (12:21 p.m. EST), NASA's Stardust-NExT mission spacecraft is within a quarter-million miles (402,336 kilometers) of its quarry, comet Tempel 1, which it will fly by tonight. The spacecraft is cutting the distance with the comet at a rate of about 10.9 kilometers per second (6.77 miles per second or 24,000 mph). The flyby of Tempel 1 will give scientists an opportunity to look for changes on the comet's surface since it was visited by NASA's Deep Impact spacecraft in July 2005. Since then, Tempel 1 has completed one orbit of the sun, and scientists are looking forward to discovering any differences in the comet. The closest approach is expected tonight at approximately 8:40 p.m. PST (11:40 p.m. EST). During the encounter phase, the spacecraft will carry out many important milestones in short order and automatically, as the spacecraft is too far away to receive timely updates from Earth. These milestones include turning the spacecraft to point its protective shields between it and the anticipated direction from which cometary particles would approach. Another milestone will occur at about four minutes to closest approach, when the spacecraft will begin science imaging of the comet's nucleus. The nominal imaging sequence will run for about eight minutes. The spacecraft's onboard memory is limited to 72 high-resolution images, so the imaging will be most closely spaced around the time of closest approach for best-resolution coverage of Tempel 1's nucleus. At the time of closest encounter, the spacecraft is expected to be approximately 200 kilometers (124 miles) from the comet's nucleus. The mission team expects to begin receiving images on the ground starting at around midnight PST (3 a.m. on Feb. 15 EST). Transmission of each image will take about 15 minutes. It will take about 10 hours to complete the transmission of all images and science data aboard the spacecraft. Live coverage on NASA TV and via the Internet begins at 8:30 p.m. PST (11:30 p.m. EST) from mission control at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Coverage also will include segments from the Lockheed Martin Space System's mission support area in Denver. A post-flyby news conference is planned on Feb. 15 at 10 a.m. PST (1 p.m. EST). For NASA TV streaming video, scheduling and downlink information, visit: http://www.nasa.gov/ntv . The live coverage and news conference will also be carried on one of JPL's Ustream channels. During events, viewers can take part in a real-time chat and submit questions to the Stardust-NExT team at: http://www.ustream.tv/user/NASAJPL2 . During its 12 years in space, Stardust became the first spacecraft to collect samples of a comet (Wild 2 in 2004), which were delivered to Earth in 2006 for study. The Stardust-NExT mission is managed by JPL for NASA's Science Mission Directorate in Washington.

Re: [meteorite-list] Yet another PA fireball
I think I may have found it on radar. The radar data is noisy on all the radars in range, but there is one feature that appears in the 1736 UTC data set of the KDIX radar outside Philly. It features multiple altitude signals and a Doppler velocity pair (i.e. turbulence). Location is 40.19498, -73.6645. If it is a meteorite signature then it is roughly the size of the Grimsby fall. Two words: Scuba gear. Or two other words: Fishy Squisher. This is preliminary and I could be wrong - especially given how noisy the radar imagery is - but it looks like a decent radar signature in the general area and direction where the fireball was reported. I'm getting the location and direction from Mike Hankey's work and the time from the myfoxphilly.com news report. Rats.

[meteorite-list] Looking to Buy. Trying to "complete" my type set. THERE IS A NEW CHONDRITE TYPE....
Hello Richard Listers, Not sure if you seen the news about Almahata Sitta, but I think this would be up your alley because you collect Type meteorites. Take a look at the new findings from the MAPS journal from OCT-NOV issue. http://adsabs.harvard.edu/abs/2010M%26PS...45.1657H Abstract Among the several hundred, mostly small meteorite fragments, recovered within the Almahata Sitta strewn field, one fragment (MS-CH), weighing 5.68 g, was detected that represents a new type of chondritic meteorite. The detection of short-lived cosmogenic radionuclides clearly indicates that this chondrite fragment results from a fresh meteorite fall consistent with the Almahata Sitta event in October 2008. The fundamental mineralogical characteristics of the Almahata Sitta fragment MS-CH can be summarized as follows: (1) the almost equilibrated olivine has high Fa contents of about 36 mole%. The fragment is of petrologic type 3.8 ± 0.1; (2) the metal abundance of the rock is on the order of 2.5 vol%; (3) the mean chondrule size has been determined to be roughly 450 μm; (4) point-counting and imaging indicate that the matrix abundance is approximately 45 vol%; (5) Cr-spinels have much lower TiO2 concentrations than typical spinels within R chondrites; (6) calcium-aluminum-rich inclusions are spinel-rich and severely altered having abundant Na- and/or Cl-rich alteration products. Spinel also contains significant concentrations of Fe and Zn; (7) magnetites and platinum-group element-rich phases (sulfides, tellurides, and arsenides) characteristic of both R and CK chondrites were not found in fragment MS-CH; and (8) the mean oxygen isotope composition of three small fragments of Almahata Sitta MS-CH is δ17O = +4.35‰, δ18O = +4.94‰, and Δ17O = +1.76‰. The oxygen isotopes relate MS-CH to R chondrites. No established chondrite group having all these characteristics exists.

Re: [meteorite-list] Looking to Buy. Trying to "complete" my type set. THERE IS A NEW CHONDRITE TYPE....
Dear Listers: Also the K -type chondrites should also be considered: The Kakangari (India 1890 fall), LEWIS CLIFF 87232 (Antarctica, 1987 find), and the Lea County 002 (New Mexico, 1988 find) K Chondrites have a similar set of petrologic and oxygen isotopic characteristics that distinguishes them from other chondrite groups. They here established to constitute a single chondrite grouplet--the K Chondrites (named after the Kakangari chondrite which fell in India June 4, 1890). K Chondrites are not affiliated with any of the three--E, O, or C--chondrite classes but have some characteristics that are similar to those of each class. Their characteristics also do not fit the concept that the petrologic and chemical properties of chondrite groups are a smooth function of formation at specific heliocentric distances from the sun.

Re: [meteorite-list] Help "Self Classify & Pair" my new stone
Hi Richard, Bernd, and List, Bernd is right (as usual), this is probably not an H. Sometimes the amount of visual iron can be deceiving. I have seen some L's and LL's with plentiful metal fleck. But it's almost surely a type-4 - not enough chondrules for type 3 and too many for type 5 or 6. So this could be an L4, LL4, maybe an H4, or perhaps some combination or transition like L/LL4.

[meteorite-list] Ibitira
Hello all, I'll be leaving for dinner shortly so I may not reply tonite. My question: does anyone have a TS of Ibitira for sale or loan? Others on this list will (i quess) vouche for me. I'm setting up the scope & equip. for a shoot of about 30 TS's shortly, to add to my EoM pics and would love to add an Ibitira. If it's a loan i will state such.

When you pointed out a number of additions I was missing, I added those to my list and obtained more specimens. A type collector can go nuts typing to pursue every single subdivision of any "set", but that's the same thing any collector has to deal with, no? On the other hand a collector could obtain a stone, an iron and a mesosiderite and consider his type set complete. Most of us are somewhere in between. Realistically I can't chase the rarest of the rare sub-groups. There just isn't enough material available nor is my budget very large. I have to pick and choose what "complete" means for me and sometimes a few milligrams is all I have or can afford of the type. However this is enough to fill the hole in the set. I've had a number of people offer specimens that would fill some of my needed types, but is sizes that are out of my budget. Sometimes nearly complete is the best one can do... One obvious thing that becomes apparent as the list expands is some types are just not available. Those are listed on my master sheet as such, but don't appear as "needed". If any of the unavailable types falls and becomes available to the collector market, then the type would be come "needed". The same goes for the rare sub-types, but for now I don't feel the need to include them. Finally as collecting tastes change, the desire to maintain the type collection as complete as possible often wanes in the collector as new avenues of knowledge are opened. Just some of my thoughts on collecting (not just meteorites) which I have acquired over the past few decades. I'm sure everyone else does things their own way...

Re: [meteorite-list] Looking to Buy. Trying to "complete" my typeset. THERE IS A NEW CHONDRITE TYPE....
I too am a type collector but like Richard sais, I cannot afford to collect all the little "nuances" types. I just try to get one of each type group, i.e. IA, IB, IIA,IIB, and each one of the achondrites but not all the 3.8, 3.9, etc. Basically one of each "headings" you have listed.

[meteorite-list] AD - looking for a piece of Gibeon
List, I'm looking for a smaller piece of Gibeon in the 200-600g range, preferably a whole individual with nice surface features, but an end or corner cut would be acceptable as well. I would prefer it to be unetched, the exterior surface features are what I am most interested in. Rusty 'as-found' or cleaned up is fine, no preference.
