Re: [meteorite-list] terminology
With such a massive object, I sure hope we will see data come out on the sonic boom (traveling wave) and then the burst. Sonic booms can happen on any size object (pretty much) and the smaller the object, the harder the boom to hear. So after the main event, were the pops something on the ground, small sonic booms, or bursts from smaller objects...as you say releasing energy??? A lot of this information will be dependant on what kind of environmental monitoring they do in Russia. I know energy from the main burst was recorded in Antartica via infrasound.

Re: [meteorite-list] What was the true azimuth of the Russian meteor?
Hi Bjorn, I've been gone on vacation for 5 days so I don't know if your question below was adequately answered yet, but there is no discrepancy between the two pictures. As I pointed out last week in one of my posts, while the trajectory appears to be parallel to the Kazakhstan/Russian border in the Meteosat-9 image, the meteor was NOT travelling parallel to the ground, so its ground track was definitely oriented more clockwise than the ~80-degree azimuth of the country border. From Meteosat 9's perspective, the bolide was very nearly on the limb, so you are seeing it severely foreshortened. More importantly, the east end of the contrail (right side) is at a higher altitude than the west end. As a result, when you project the 3D track down to the ground, it will actually start on the Kazakhstan side of the border. --Rob -Original Message- From: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] On Behalf Of Bjorn Sorheim Sent: Sunday, February 17, 2013 10:52 AM To: meteorite-list@meteoritecentral.com Subject: [meteorite-list] What was the true azimuth of the Russian meteor?

On Sol 3221 (Feb. 14, 2013), it was planned to have the rover perform a very small turn to position the robotic arm for an acceptable surface target, but a Deep Space Network issue prevented the command sequences from reaching the rover. With imagery subsequently returned from Opportunity, an acceptable target was found within reach of the arm, negating the need for a turn. On Sol 3224 (Feb. 17, 2013), Opportunity used the Rock Abrasion Tool (RAT) to brush the surface target 'Maley,' which was then followed by a Microscopic Imager (MI) mosaic and a placement of the Alpha Particle X-ray Spectrometer (APXS) for an overnight integration. With work complete at this location, on Sol 3227 (Feb. 20, 2013), the rover drove approximately 120 feet (36.5 meters) to the southeast towards the rock target 'Big Nickel' to begin an in-situ investigation there. No 'amnesia' events with the Flash file system have occurred since Sol 3183 (Jan. 6, 2013), and the rover is otherwise in good health.

There was extreme detail of this fireball from my location, Leslie A. of La Crescenta reported to AMS. I actually saw flames with a trail of glowing lime green attached to it. very large in size. We are up toward the mountains. One user on Instagram posted a photo, with the caption, Truly feel lucky ti [SIC] have seen one of these tonight! #meteor #small #toclose [SIC] #scary #exciting! Slavik L. of Los Angeles wrote, The glowing long trail was with it the entire time it was in my vision. From overhea until it looked like it went into the Silver Lake Reservoir. He continued, The glow of the fireball was very thick and then at the end very small trail. Everything was blue and white. The LA light show Thursday was particularly memorable for Micah P. of Glendale. I've seen a few astronomical occurrences in my lifetime but nothing like this, he said. I'm an amateur photographer and I was too shell shocked to grab my camera!! But I'll never forget it either!!! The sightings come days after Bay Area residents witnessed a stunning fireball shoot across the sky, and Floridians witnessed a meteor shower.

[meteorite-list] Injured Russians Leave Hospital, Analysis of Meteorite Fragments Begins
http://www.cnn.com/2013/02/22/world/europe/russia-meteor/index.html Injured Russians leave hospital, analysis of meteorite fragments begins By Laura Smith-Spark CNN February 22, 2013 (CNN) -- Twenty-five people were discharged from hospital Friday, state media reported, a week after a meteor exploded in spectacular fashion in the skies above Russia's Urals region, shattering glass in thousands of buildings. Eleven children were among the patients who went home Friday morning, the state-run RIA Novosti news agency reported. More than 60 people were hospitalized across the region, the local emergencies ministry said. The total count for those hurt climbed in the days after the meteor's arrival on February 15 to more than 1,500, according to RIA Novosti. Most of the injuries were minor and caused by flying glass. The Chelyabinsk region, the hardest-hit area, asked federal authorities Monday for $16.6 million in aid, RIA Novosti said. The total bill for the damage is estimated at 1 billion rubles ($33 million), with more than 4,000 buildings affected, many of them apartment blocks. About 200,000 square meters (almost 240,000 square yards) of glass were broken in total, authorities said. Meanwhile, the first fragment of meteorite arrived in Moscow on Friday for analysis, RIA Novosti reported. About 50 small fragments have been found so far, the news agency reported earlier this week, some in a crater in the Chelyabinsk region's Lake Chebarkul. Images taken soon after the meteor blast showed a hole in the ice covering the lake where a chunk of meteorite was believed to have fallen. Because the meteor exploded in a huge fireball in the atmosphere, the fragments could be scattered over a huge area. A couple of purported pieces of Chelyabinsk meteorite were advertised for sale on the eBay online auction site Friday. The national space agency, Roscosmos, said scientists believe one meteoroid entered the atmosphere, where it burned and disintegrated into fragments. Amateur video footage showed a bright white streak moving rapidly across the sky before exploding with an even brighter flash and a deafening bang. According to NASA estimates, the meteor measured 55 feet (17 meters) across and had a mass of 10,000 tons. The space agency put the amount of energy released in the meteor's explosion at nearly 500 kilotons. By comparison, the nuclear bomb the United States dropped on Hiroshima in 1945 released an estimated 15 kilotons of energy. The whole event, from the meteor's atmospheric entry to its disintegration in the air above central Russia, took 32.5 seconds, NASA said. Residents told CNN of their shock as they saw, heard and felt the awesome blast, and the chaos and confusion they witnessed in the moments afterward, when no one knew what had happened. Denis Kuznetsov, a 23-year-old historian from Chelyabinsk, told CNN via e-mail of his experience. At first there was a blinding flash lasting several seconds, which made him want to shut his eyes. The light shone like 10 suns, he said. This is no exaggeration. Kuznetsov said he experienced what felt like a push, as a sound wave passed through his body. For some seconds I simply stood, he said, amid the sound of breaking glass. Interior Minister Vladimir Puchkov told state news agency Itar-Tass this week that he wanted to see scientists develop new technologies that would allow such meteors to be spotted in advance. I believe that this emergency situation will push us towards generating new resources, approaches and ideas in tackling this serious problem, he is quoted as saying. The European Space Agency said that events of the magnitude of the Chelyabinsk meteor blast are expected once every several of tens to 100 years. It calculates that the meteoroid burst and disintegrated about 15 to 20 kilometers (nine to 12 miles) above the ground. The terminal part of the explosion probably likely occurred almost directly over Chelyabinsk, said Detlef Koschny, of the European Space Agency. This was perhaps the single greatest contributor to the blast damage. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

There was extreme detail of this fireball from my location, Leslie A. of La Crescenta reported to AMS. I actually saw flames with a trail of glowing lime green attached to it. very large in size. We are up toward the mountains. One user on Instagram posted a photo, with the caption, Truly feel lucky ti [SIC] have seen one of these tonight! #meteor #small #toclose [SIC] #scary #exciting! Slavik L. of Los Angeles wrote, The glowing long trail was with it the entire time it was in my vision. From overhea until it looked like it went into the Silver Lake Reservoir. He continued, The glow of the fireball was very thick and then at the end very small trail. Everything was blue and white. The LA light show Thursday was particularly memorable for Micah P. of Glendale. I've seen a few astronomical occurrences in my lifetime but nothing like this, he said. I'm an amateur photographer and I was too shell shocked to grab my camera!! But I'll never forget it either!!! The sightings come days after Bay Area residents witnessed a stunning fireball shoot across the sky, and Floridians witnessed a meteor shower. But by far the most spectacular was, also this month, a meteor that blazed across the western Siberian sky and exploded with the force of 20 atomic bombs, injuring more than 1,000 people. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list -- Jim Wooddell jimwoodd...@gmail.com 928-247-2675 __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Video selection criteria
Hi Mike - From what you are saying, it looks like some musicians have gotten hold of the original videos and added their own songs to them, intending to get royalties from the views of videos which they had no rights to use in any way. At the same time, the original Russian musicians whose music was playing on those car radios have no way to earn any royalty money from those views. 100,000,000 views so far. It looks to me like this is going to end up like the Tetons Fly-by movie, so if any of you have the ability to snag any of the original videos, I suggest you do so. good hunting, Ed --- On Fri, 2/22/13, Galactic Stone Ironworks meteoritem...@gmail.com wrote: From: Galactic Stone Ironworks meteoritem...@gmail.com Subject: Re: [meteorite-list] Video selection criteria To: E.P.

Above all, I wanted clear videos of higher quality. Many videos are low-resolution and pixelated. Some are out of focus and jumpy. And a few had very loud and awful music blaring the entire time. A large portion of the videos showed the same thing - the trail in the sky and the damage afterwards. A relatively-small number are clear, well-shot, and contain intelligible audio as well - those are the ones I was looking for. And some personal bias slipped in - the video with the dog, the woman screaming in surprise, etc. Those kinds of videos just struck me in some way. I finished up looking through several dozen more last night and today, and I didn't find any more worth sharing - just more of the same. I keep hoping to run across another video like #7 (which turned out to be fake) - something that clearly shows the leading edge of the bolide while the trail is being formed. I have yet to find a genuine video of that.

[meteorite-list] Russian: A preliminary reconstruction of the orbit of the Chelyabinsk Meteoroid byJorge I. Zuluaga Ignacio Ferrin
From the email updates of Stefan Geens' site: http://ogleearth.com/2013/02/reconstructing-the-chelyabinsk-meteors-path-with-google-earth-youtube-and-high-school-math I learnt that a paper has been written regarding the entry path, working back to possible orbits: http://arxiv.org/abs/1302.5377 A preliminary reconstruction of the orbit of the Chelyabinsk Meteoroid Jorge I. Zuluaga, Ignacio Ferrin Instituto de F´ısica - FCEN, Universidad de Antioquia, Calle 67 No. 53-108, Medellın, Colombia Abstract In February 15 2013 a medium-sized meteoroid impacted the atmosphere in the region of Chelyabinsk, Russia. After its entrance to the atmosphere and after travel by several hundred of kilometers the body exploded in a powerful event responsible for physical damages and injured people spread over a region enclosing several large cities. We present in this letter the results of a preliminary reconstruction of the orbit of the Chelyabinsk meteoroid. Using evidence gathered by one camera at the Revolution Square in the city of Chelyabinsk and other videos recorded by witnesses in the close city of Korkino, we calculate the trajectory of the body in the atmosphere and use it to reconstruct the orbit in space of the meteoroid previous to the violent encounter with our planet. In order to account for the uncertainties implicit in the determination of the trajectory of the body in the atmosphere, we use Monte Carlo methods to calculate the most probable orbital parameters and their dispersion. Although the orbital elements are affected by uncertainties the orbit has been sucesfully reconstructed. We use it to classify the meteoroid among the near Earth asteroid families finding that the parent body belonged to the Apollo asteroids. The authors cite Stefan Geens' work as the starting point for their calculations. They have an updates page: http://urania.udea.edu.co/sitios/facom/research/chelyabinsk-meteoroid.php This paper is also linked to and cited within the Wikipedia page: http://en.wikipedia.org/wiki/2013_Russian_meteor_event which mentions another page of potential interest: http://www.amsmeteors.org/2013/02/large-daytime-fireball-hits-russia/ - Robin __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Zuluaga, Ignacio Ferrin Instituto de F´ısica - FCEN, Universidad de Antioquia, Calle 67 No. 53-108, Medellın, Colombia Did not know the precise location of the Korkino marketplace video: http://www.youtube.com/watch?v=odKjwrjIM-k and they based their range of trajectories on a rough estimate of vertical elevation from the Korkino area. I wrote to them referring to parts of Stefan Geens' page: http://ogleearth.com/2013/02/reconstructing-the-chelyabinsk-meteors-path-with-google-earth-youtube-and-high-school-math/#comment-7594 where the marketplace is identifies. Further comments: http://ogleearth.com/2013/02/reconstructing-the-chelyabinsk-meteors-path-with-google-earth-youtube-and-high-school-math/#comment-7584 enable us to locate roughly which lane of the market place the camera was located. It doesn't really matter which lane it was - the important thing is to know the angle of the lanes with respect to east-west. Maybe they will be able to narrow down their estimation for this middle part of the path. They used Lake Cherbarkul as the other reference point, however, this is after the fragments have slowed their horizontal movement and been more affected by gravity, so it would not be correct to assume a straight line trajectory from the approximately above Korkino area at a given altitude, determined by Stefan Geens' (or the authors') triangulation from the Revolution Square video. Perhaps a better straight line approximation could be found by using the meteorite fall location which is most to the west. That object would presumably have been traveling faster and so be less affected by gravity than those which fell more to the east. I pointed them to the video of the rapid slowing of the multiple objects after the main conflagration: http://www.youtube.com/watch?v=gQ6Pa5Pv_io I suggest switching to full-screen and starting the player at 4:30. http://postimage.org/image/zdzm79g95/ and I mentioned this mailing list. I will write to them again with the above and suggest they might like to join this list and ask for guidance on how to estimate the slowing of the objects and therefore the bending of the trajectory before it reaches ground. Is there any consensus on the most westerly location where fragments came to Earth? - Robin __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

There's no mention of the exact location of this report: http://www.bbc.co.uk/news/world-europe-21552923 Just look for the holes in the snow and start digging. The reporter and crew found four fragments after just a few minutes digging in the snow.

People were scared when the meteorite flew above us. But now, everyone is excited and will be excited for probably a hundred years. Other locals, who are also named, hold meteorites and say they will sell some of them. I guess the biggest fragments would generally be more to the west. I haven't seen a map of the strewn field.
