Tucson Region In our Tucson paper this morning: Streaking fireball a vivid spectacle in daytime sky By Shelley Shelton Arizona Daily Star Tucson, Arizona | Published: 08.24.2008 A fireball hurtled across the southern Tucson sky in broad daylight Saturday morning, startling and inspiring awe in those who saw it. Chelsey Dever was working a yard sale at her grandmother's house on the Northwest Side around 10:30, she said, when she looked toward the south and saw the ball arcing through the sky. At first I was like, 'Is that an airplane that's on fire?' she said. Then she realized it wasn't. The other two people outside with her at the time didn't see it. Across town, Catherine O'Sullivan was riding her bicycle southbound on Sabino Canyon Road when she looked up and saw it, she said. It looked like someone put a fiery ball in a catapult and launched it, she said. O'Sullivan said she used to work in a planetarium and was guessing the fireball was a bollide a big meteorite. For one to come this close in the atmosphere and be seen during the day, it's just unheard of, she said. Richard Dougall, equipment loan coordinator for the Tucson Amateur Astronomy Association, said he was thrilled to see the meteor as he drove south on Kolb Road. It was a fireball. It was beautiful, he said. I've been in seventh heaven all morning. He was so entranced, he almost forgot to pay attention to his driving, he said. When asked how common it is to see such a thing in broad daylight, he responded, Not. I've always wanted to see one in daytime, he said. He's been a member of the astronomy group since 2001 and has seen quite a few at night, he said. This one had the bright reddish-orange color of a road flare, he said. He guessed that it was probably 200 or 300 miles to the south, maybe farther, but said it's always hard to tell. Even though it's unusual to see a meteor or meteorite during the day, Dougall said they are pretty common. The Earth gets struck constantly by meteorites. Constantly, he said.

[meteorite-list] follow up on Ziz vs. new iron RFSPOD August 14
to all interested, The Hmanis asked me to forward a follow up on their new irons including a 34kg specimen they had displayed at this year's Enisheim/France meteorite fair. One of the new finds acquired from another dealer was kindly posted by Michael Johnson as Rocks from Space Picture of the Day on August 14. M. Hmani informed me that he had meanwhile been issued a certificate by the Etudes Metallurgiques et de Traitment Thermique (EMTT) which arrives to the conclusion that grain size and structure of the new material is identical with Ziz (NWA 854). Mr. Hmani was so kind to forward me the certificate on my request and allowed me to upload the paper on my website: http://www.meteorite-recon.com/en/Meteoritensammlung.htm (see Inventory # B-0243) To my understanding the paper states that the questioned iron is an og octehedrite such as Ziz. According to the certificate a microscopic analysis of an etched surface has been performed but no element mapping or neutron activation scan. I assume, the certificate does not intend to claim a pairing. Please note that this is my personal opinion. cheers Svend www.meteorite-recon.com __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Even though it's unusual to see a meteor or meteorite during the day, Dougall said they are pretty common. The Earth gets struck constantly by meteorites. Constantly, he said. Sounds like if the interviewer had probed Mr. Dougall's thoughts a bit deeper, he might have said: I'm always dodging the damned things left and right. They're mighty pesky critters, them meteorites. Had a really close call with one last Thursday. Almost got it right in the teeth. Just one little misstep or miscalculation as to their speed or trajectory and you're fried mush. It's a bloomin' wonder more people aren't hit by the rascally things. But then maybe that's why we seem to be having so many mysterious disappearances lately. People that are hit by a fast, sizable fireball are immediately vaporized. Happens so fast nobody notices. Just the smell lingers a bit. But even that's gone in a hurry if there's any breeze. Yep, meteorites are probably the culprit, all right. Seems like it's way past time for a major government investigation into the matter. Or not.

Re: [meteorite-list] A Crater Wrong?
Hi, EP, If we were looking at The Moon instead of Australia, it would be less confusing. We are so much less opinionated about the Moon than the home planet. Not mentioned in this article is that there is already a huge crater in Australia, the Acraman Crater, with a ring at 90 km and another at 160-km, which has been dated to 578mya, virtually the same age as has been proposed for this crater (584mya). This is the Late Vendian period, geologically, and the time of a major extinction. Acraman required a 3-mile (5 km) diameter impactor, and produced at least a 1,000,000 Megaton impact, and has a 300-mile ejecta blanket. The Acraman event has been suggested as having a major effect on the evolution of life on Earth: http://aca.mq.edu.au/files/ahill_SETINews2003.pdf The upper 2500 meters of the Acraman crater has eroded away in the half billion years it's been there! When I stand back from the planet with Google Earth, I see a vaguely defined giant outer ring, but not a circular one as mapped in the article. It is clearly an east-west elliptical feature and the outline is not marked by any consistently elevated features (mountains, hills, faults) as a rim would be. It is largely a gigantic contrast feature. It may be the outline of that pre-Cambrian inland sea that we know did exist there. It looks suspiciously like an ancient ejecta blanket to me. And, it could be both: an ancient seabed filled with a kilometer(s)-deep ejecta blanket. Or, it could be nothing but a coincidental contrast feature. The Acraman crater is right on the rim of the ejecta blanket ellipse. About the right size for a secondary crater from so huge an impact, if one happened. (Any secondaries closer in would be buried by ejecta.) The guy's whole case is entirely suggestive rather than evidential, at least up to the pseudotachylite.. It's no surprise the government geologists in Australia were uninterested. You have to remember that impact is not entirely accepted theory in Australia. As late 1978, the man called the dean of Australian geology, was writing textbooks that asserted that the craters on the Moon were all volcanic, that tektites were produced in cryptovolcanic events, not impact craters (because there are no impact craters on Earth), and that the impact theory was an American fantasy. I would imagine Australian geologists are just getting free of that training. Connelly should send his data to the Australian geologists who found (and recognized) the Acraman crater. Any impact this huge should have left a massive amount of evidence in subsurface strata. On the other hand, Connelly could be finding and conflating evidence of Acraman into his picture of events. Or, there could be another crater, even bigger than Acraman, probably very deeply buried under that old seabed. Connelly's small gravity map doesn't show very circular or radial features. It's doesn't look like Chicxulub, for example. If anyone wants to look at the full-sized gravity map of Australia, here it is (it's a JPEG of about 7 Megabytes!): http://www.ga.gov.au/image_cache/GA11515.jpg Acraman doesn't show up on it, either, at least not on this scale or in any obvious (to me) way, but it was gravitic anomalies that got it spotted in 1997. Look at the Ring-and-Rift patterns for Australia (p. 169)! http://books.google.com/books?id=K4tv9_cRtvUCpg=PA169lpg=PA169dq=acraman+gravity+mapsource=webots=zgCvftVNMUsig=PPxR790YeI4-SxuwDCZ7D735Lxkhl=ensa=Xoi=book_resultresnum=2ct=result#PPA169,M1 You couldn't ask for a better map of the ancient basined surface of an earlier Earth than that. Wow! Not convinced yet... but I would never tell anybody with a whacky idea to quit, just keep digging. It is interesting that a local came up with a similar idea from different (and on the ground evidence). And there is that pseudotachylite evidence. Time will tell. Sterling K.

[meteorite-list] Acraman Corections
Hi, EP, List, George E. Williams, a mining geologist at Broken Hill Mine, first suggested Acraman was a crater as long ago as 1986: http://www.sciencemag.org/cgi/content/abstract/233/4760/200 Gene Shoemaker wrote about it in 1996. (Sorry, no link.) The Acraman impact was bigger than I said: 5 or 6 million megatons, rather than only one million megatons! There are the required iridium traces and some big shatter cones, too, so all the signs are there for Acraman. It appears now that more like 5000 meters of crust have eroded out of the crater since it formed. There is suspicion that the event extincted the mysterious Ediacaran fauna. http://www.informaworld.com/smpp/content~db=all?content=10.1080/08120090500181036 And the Australians are now officially referring to Acraman as the Acraman-Bunyeroo Event. Don't ask me what a Bunyeroo is... Maybe a relative of the Bunyip? Sterling K.
