[meteorite-list] Ordinary Chondrites' Parent Body
Hello List: If you read the (future) third edition of Dr. Harry McSween's book Meteorites and their Parent Dwarf Planets and Small Solar System Bodies, there may be some editing on the subject of the Parent Body for Ordinary Chondrites: The L-chondrite and LL chondrite parents, specifically were considered the best match for the small-fry 7-km diameter asteroid 3628 Božnémcová (Boznemcova). While it wasn't expected that this small asteroid was the overall parent of these meteorite classes, it was the starting point. The latest issue of Meteoritics and Planetary Science has an article where doubt is cast upon that hypothesis after a detailed analysis of the reflectance spectrum of Boznemcova. The authors conclude that Boznemcova doesn't match as well as thought, and is instead has the surface of a somewhat differentiated angrite-like basalt - of the kind never sampled on Earth. So that would leave the common L's and LL's as orphans still with the observations that some Earth crossing asteroids are somewhat similar but no cigars. Ref: CLOUTIS, BINZEL, BURBINE, GAFFEY, McCOY, Asteroid 3628 Boznemcova: Covered with angrite-like basalts?, MPS, V. 41, (8), p. 1147, (2006). As for the H-Chondrite parent body, nothing new here on 6 Hebe. Except that if you have a pair of binoculars and dark sky, now is the time to see 190-km diameter Hebe. It was brightest at its August 5 opposition and now is to moving out more quickly. But Hebe is still bright (mag. 8.4). Nearly as bright as a currently very bright Neptune (mag. 7.8), and both objects are in Capricornus and make for good evening viewing.

AW: [meteorite-list] Moss classification speculation
Hi Fred, A little addendum: there are some ordinary chondrites, which are very fragile too. The porous Baszkowka is so friable, that it can't be cut into thin slices without being embedded before. Saratov is very crumbly and whoever tried to ship a Bjurbole, knows the hard challenge to find a packing method, for the receiver not getting a box full of dust with assorted chondrules. Hmm, I remember back to the themes' list of the Casablanca conference. Wasn't there a suggestion to hunt in desert especially for CIs too? If I think how horribly crumbly and friable Ivuna or Orgueil is (not to mention Tagish Lake as another C) I'd guess that would be a bold venture.. as I would expect that those types will decompose to dust within shortest time. Can certainly be the reason also for the mere Antarctic record of those types, can't it? That, what me makes so perplex, is that on Mike's pictures it has s much metal, here the links again: http://meteoriteguy.com/sale-pics/mosscutb.JPG http://meteoriteguy.com/sale-pics/mosscutd.JPG I can't remember to have seen so much iron in a CO3.

Well, Jeff I don't think, that Moss is very friable, Maybe crumbly on fragmented sides leaving some dust, as reported. Because think! One stone chopped off two branches from a tree and remained entire, the other one hit on metal and only a minor part was chipped off and finally one even penetrated a roof and survived it. So there is a difference to the CIs or Tagish Lake. Hehe, remember the huge ice cubes cut out of the lake with the dust and crumbs spread inside.

Re: [meteorite-list] Moss classification speculation
Well it's true Martin and I also have our Tanezrouft 060 that is very fragile, but does not look like a carbonaceous. So let's say that for the clue to be better, it must also look like a carbonaceous. But you are right and we can only keep on guessing as long as the analysis results are not known. Regarding metal, I can't say accurately, but Acfer 333 (a CO3) is showing a strong attraction to a magnet, much more than a CM2 or a LL, let's say similar to some L chondrites almost. There is no metal visible as it is weathered, but maybe it was somehow like that when it fell? Just another guess, one more!!!

[meteorite-list] Preliminary MOSS meteorite classification
Hello everyone, well here is the preliminary classification data on the MOSS Norway meteorite fall. Dr Jeff Grossman is doing the classification and he sent me the following information a little while ago. I have removed some parts of the email which is not for public release yet, but the basics are here. Please do not bombard him with questions, as he is very busy working on it and it wont help. Further work is ongoing, including oxygen isotopes and Direct from Dr. Grossman I now have the first probe data on Moss, and I can give you an initial classification. Please remember that chondrites are classified not just on the petrologic characteristics, but even more so on their bulk and isotopic compositions (work ongoing) As surprises are always possible, I consider my classification to be provisional. Petrologically, Moss is a CO3. It contains chondrules, CAIs, AOIs, and metal/sulfide grains in the appropriate size range (done visually (ongoing). The distribution of chondrule types is typical for a CO3. The metal + sulfide abundance is also appropriate for CO3 chondrites. I did a point-count on a 6x6 mm area of a thin section. The results are shown here with data from McSween (1977) for all the other CO falls: Metal FeS Kainsaz (CO3.2) 5.9 1.5 Felix (CO3.3) 2.1 4.1 Ornans(CO3.4) 1.5 3.9 Lance (CO3.5) 1.3 4.6 Warrenton (CO3.7) 1.4 2.1 Moss 2.2 2.4 As for petrologic type, my initial guess of 3.5 looks pretty good. The histogram of Fa content in random olivines looks generally like one published for Ornans in 1969. Comparing to Van Schmus's 1969 data, we get: Avg Fa PMD Kainsaz (CO3.2) 11.870 Felix (CO3.3) 18.470 Ornans(CO3.4) 19.068 Lance (CO3.5) 21.263 Warrenton (CO3.7) 33.921 Moss 19.965 This puts Moss between Ornans and Lance, although I don't think that difference is significant. Based on the amount of FeO diffusion into olivines in type I chondrules observed in the SEM, I'd have to say Moss is at least as metamorphosed as Lance. I'll call it CO3.5 for now, but I would not be surprised if further study bumps it up to CO3.6. Finally, the shock stage appears to be S2 or S3, but I haven't classified this parameter in other CO chondrites, so I'll have somebody check up after me. Jeff I will continue sales again, now that we know it is not a Kakangari Chondrite. I want to thank Dr. Grossman for working so hard to get the first carbonaceous chondrite fall in many years classified so quickly. Specimens have been distributed to scientists all over the country for analysis so I expect many papers on this fall to be written in the near future.

Re: [meteorite-list] Meteorwrong ;-) falls in Brazil
Hi Cometfinder Rob ! While you work that (space) junk out ... C/2006 M4 (SWAN) Discovered by Rob Matson and Michael Mattiazzo June 20, 2006 Congratulations this time you got the big one !! In another month we can all probably see M4 in the binoculars ... and if it doesn't get too diffuse maybe as brightly or even brighter than any of the asteroids ! Way to go. ref: http://ares.nrl.navy.mil/sungrazer/index.php?p=news_arch2006 As with SWAN's previous discovery, Rob Matson has been kind enough to share his discovery story, plus some images from Rob McNaught and Sebastian Hoenig. I first spotted the comet around 10:30 am exactly a week ago today when the 7/5 SWAN image was first posted. I should have spotted the comet a few days earlier, but as I later explained to Brian Marsden and Tim Spahr at MPC, I missed it because it was hugging one of the superimposed gridlines. By the time of the 7/5 image, though, the comet had enough separation from the grid line to draw attention to itself. I e-mailed Eric Christensen at Catalina Sky Survey (with whom I'd been working on a different SWAN candidate) that our old phantom had disappeared, but had been replaced by something much more promising, and I would get back to him once I confirmed it wasn't a known comet. By 11 am I had checked known bright comets and found no matches, but wrote Eric back that due to the sky location, the southern hemisphere was the only hope for confirmation. I measured pixel positions for six nights from 6/20 to 7/5, converted to ecliptic coordinates and then to equatorial. I checked residuals on a parabolic orbital solution, tweaked a few positions until I was satisfied, and at 1:22 pm sent a discovery report and rough ephemeris to Brian and Tim Spahr at MPC. Ten minutes later I sent the same positions to Eric. Since the southern hemisphere was the only hope for confirmation, the next step was to contact Rob McNaught and Gordon Garradd at Siding Spring Observatory to see what they could do. Like most observatories, SSO was down for full moon and wasn't planning their next run until Thursday. But just in case, I sent Rob and Gordon predicted comet positions for Monday and Tuesday, and told them if no additional SWAN images appeared by Wednesday, I'd extend the ephemeris a few more days. That evening I was able to check my e-mail and confirm that Tim had gotten my message; also, Rob replied that he would try for the comet on Thursday from the Uppsala telescope. There were no new SWAN images Tuesday so I went ahead and extended the ephemeris through Friday for Rob, running some excursions to give him an idea of positional uncertainty. A few hours later, Rob replied that Michael Matiazzo had independently found the same comet and reported it to him. He also indicated that he was thinking about heading up to SSO a day early if the weather cooperated. Well, late Tuesday night (Wednesday afternoon for Australia) Rob informed me that Terry Lovejoy had located the comet in one of his June 30th survey images from Thornlands, QLD, and forwarded me Terry's crop of an image stack showing a noticeably green cometary object. The weather had cleared sufficiently for Rob to make the decision to head up to Siding Spring, so I checked Terry's position against my rough orbit to see if it needed some real-time tweaking before Rob made the recovery attempt. I didn't have all of my astronomy tools on my laptop, but working from my hotel room I decided that my predicted position needed to shift a bit to the east and to the north. I forwarded the correction to Rob and at 1 am cross my fingers and called it a night. Wednesday morning I got the blow-by-blow in a series of messages from Rob. The comet wasn't at the nominal position (no surprise), but it was off by quite a bit more than I would have expected -- nearly 3 degrees. Indeed -- it is a testament to Rob's skill and perseverance that he was able to spiral out and locate it before the comet set at his location. - Original Message - From: Matson, Robert [EMAIL PROTECTED] To: meteorite-list@meteoritecentral.com Sent: Wednesday, August 30, 2006 3:13 PM Subject: [meteorite-list] Meteorwrong ;-) falls in Brazil Hi All, Not quite a new meteorite fall, but the manmade equivalent: http://noticias.terra.com.br/brasil/interna/0,,OI1113465-EI306,00.html Will work on trying to identify the likely satellite that decayed... --Rob __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Preliminary MOSS meteorite classification
Hi all - Dammit! The only way that you would have an annual fall would be if a debris stream intersected the Earth at the same time each year. This is highly unlikely. What these people (I can't do it myself any longer) need to be looking for is regular intervals, and multiples of those intervals, between falls. Then they could establish a debris stream's orbit. If a debris stream intersection period could be established, then one could stay up on the appropriate nights, watch for bolides, triangulate, and voila, meteorites on demand so to speak. good hunting, Ed --- Bjorn Sorheim [EMAIL PROTECTED] wrote: Jeff Grossman wrote: Yes, I noticed that too.

Hi Ed: That is almost as hard to believe as meteor showers (debris from a comet) occurring on the same day each year! Actually, probably does not have to be every year, just every few years. If these come from the breakup of a near Earth asteroid, the debris would probably spread out from the asteroid in a manner similar to a comet tail. Larry Quoting E.P.

Hi Doug, I see you've been surfing around on the SOHO website! A pity that C/2006 M4 happened to have such poor timing as far as its perihelion passage. I was looking forward to seeing it brighten as it traversed SOHO's LASCO C3 and C2 fields of view, but alas it was very dim when it entered C3, and the egress was blocked by the arm that holds the solar occulting disk. (Images have also been infrequent for the last week due to the seasonal keyhole). Hopefully it will be bright enough to pick up in binocs later in September.
