People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave according to a Reuters correspondent in the industrial city 1,500 km (950 miles) east of Moscow. A fireball blazed across the horizon, leaving a long white trail in its wake which could be seen as far as 200 km (125 miles) away in Yekaterinburg. Car alarms went off, windows shattered and mobile phone networks were interrupted. "I was driving to work, it was quite dark, but it suddenly became as bright as if it was day," said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. "I felt like I was blinded by headlights," he said. http://news.yahoo.com/possible-meteor-shower-reported-easter n-russia-052833588.html ----------------------------------------------- ----------------------------------------------------------------------- http ://news.yahoo.com/asteroid-gives-earth-record-setting-close-shave-today-07140928 4.html An asteroid half the size of a football field will buzz Earth today (Feb. 15) in a big way, coming closer to the planet than many satellites, and you can watch the cosmic encounter live online. At its closest approach at 2:24 p.m. EST (1924 GMT) today, the 150-foot-wide (45 meters) asteroid 2012 DA14 will cruise within 17,200 miles (27,000 kilometers) of Earth. The encounter marks the closest flyby by such a big asteroid that's ever been known about in advance, but there's no chance that the space rock will hit us, experts stress. "No one on Earth is in danger, nor will any of our satellites be hurt or damaged," Jim Green, director of NASA's planetary science division, said in a video released by the space agency Thursday (Feb. 14). You can watch the asteroid 2012 DA14 flyby on SPACE.com today during a series of free webcasts. NASA will provide two webcast views of the asteroid, with several other professional and amateur groups joining in with other broadcasts. Scientists are excited about the flyby, for it gives them a rare chance to get an up-close look at a decent-size asteroid. Photos of the asteroid captured on Thursday show it as a growing pinpoint moving across a star-filled background. [Asteroid 2012 DA14's Flyby: Complete Coverage] "We're going to use our radars to bounce radio waves off this asteroid, watch it spin, look at the reflections and understand its size, its shape and perhaps even a little bit about what it's made of," Green said. See an asteroid in the sky The flyby of 2012 DA14 will be a treat for some well-placed skywatchers, too. While the close approach occurs during daylight hours in the Western Hemisphere, shutting out observers there, stargazers in parts of Europe, Asia, Africa and Australia have a shot at seeing the asteroid today. Even if geography favors you, you'll still need binoculars or a small telescope to spot 2012 DA14. Through such optical aids, the asteroid will appear as a point of light streaking across the sky at a rate of 0.8 degrees per minute. (For reference, the apparent diameter of the full moon as seen from Earth is about 0.5 degrees.) And wherever you may be, you can watch the flyby live on your computer. In addition to NASA's main webcast and evening broadcast by the agency's Marshall Space Flight Center, the online Slooh Space Camera will provide views from observatories in Africa and Arizona. The Virtual Telescope Project will provide images from Italy, and the Bareket Observatory in Israel also plans to host a webcast. Meanwhile, the nonprofit Planetary Society will air footage that includes NASA's telescope views and a live tour of the La Sagra Observatory in Spain where amateur astronomers first discovered asteroid 2012 DA14 in February 2012.

The present estimated energy of the air blast is a few thousand tons of TNT equivalent -- perhaps 15 to 30 percent of the first nuclear bombs. There are no reported deaths so far, which I think very lucky, considering the amount of falling glass at a time of day when many were on the sidewalks. xvvx Member send PM   block PM add to buddies Send: 2/15/2013 3:42:49 PM   Danny is going to visit the site in Russia- he is going by train direct from Australia to Russia ha ha.

Rick4girl Member send PM   block PM add to buddies Send: 2/15/2013 6:50:46 PM   I have a friend there who said it was pretty wild. Having visited there I know it reasonably well and my first reaction was "it could have been catastrophically worse" The reason is that the Mayak nuclear fuel reprocessing plant with its tons of plutonium and other weapons grade materials is only 90 miles away. Additionally, there is a VK and sarin gas incinerator located close to the lake in which part of the meteor crashed. A zinc factory was hit by part of the meteor collapsing a wall and ceiling. amazing no one was seriously hurt or killed. durak Member send PM   block PM add to buddies Send: 2/16/2013 8:52:16 AM   @kiwi: Witnesses described the flash as "blinding" in the broad daylight of yesterday morning. I've seen several videos that clearly indicate a flash MUCH brighter than the sun. __________________ Meanwhile, Russians are responding with their usual mordant humor. My favorite refers to the devastating pollution of Chelyabinsk. Reportedly, it is one of the most polluted places on earth, and its inhabitants have a short life expectancy that is wretched even by the miserable standard of Russian public health. A Russian tweeted: "The asteroid's inhabitants watched in horror as they neared Chelyabinsk, where of course neither sin nor soul nor, certainly, the air is purified." durak Member send PM   block PM add to buddies Send: 2/16/2013 9:49:58 AM   Last night, NASA made a much higher estimate of the explosion's energy, almost 500 kiloton TNT equivalent. This matches the yield of the warheads on today's US Minuteman ICBMs, and is dozens of times the yield of the nuclear bombs dropped on Japan in 1945. That the damage to Chelyabinsk was so limited, owes much to the high altitude of the blast. As awesome as the scale of the explosion may have been, it was due to simple heating of the air as the large object entered at a Mach number in excess of 50 (!!!). Its estimated speed was more than twice that of the old Space Shuttle on reentry. The NASA computation was based on data from a network of stations that monitor infrasound -- variations in atmospheric pressure at frequencies below audibility. NASA estimated the meteor's mass in the range of 7000 to 10000 tons, and its diameter in the range of 15 to 17 meters. The meteor may have been the largest space object to reach earth since the 1908 Tunguska explosion (about 100 times more energetic), also over Siberia. ________________________________________________ In other news, for those of you who are more connected to Ukraine, on Wednesday a roof collapsed at the Chernobyl nuclear station. There was no elevation of radiation readings, and no health consequence is expected. ragingbull Member send PM   block PM add to buddies Send: 2/16/2013 12:27:04 PM   If you saw it coming, how can you destroy it other than nuking it? durak Member send PM   block PM add to buddies Send: 2/16/2013 4:08:31 PM   I have seen a map of reported findings of meteorites (bits that made it to the ground). I was skeptical of first reports -- for example, people may have supposed that the collapsed factory roof was due to an object impact, but the collapse might have been caused by the pressure wave alone. As big as the meteor was, a fairly large object can be vaporized by the heat of reentry, so it is hard to predict whether meteorites will make it to earth. Along the path of the meteor, reported finds stretch from as far south as Orenburg (near the Kazakhstan border) to Tyumen. Cross-range, debris was reported as far west as Yekaterinburg (NNW of Chelyabinsk), and as far east as Kurgan (ENE of Chelyabinsk). ragingbull Member send PM   block PM add to buddies Send: 2/16/2013 7:50:24 PM   It's hard to believe that the dinosaurs were destroyed by a meteor. As big as the explosion was, no one was killed. durak Member send PM   block PM add to buddies Send: 2/16/2013 8:38:41 PM   @rb: Well, there's big, and then there's big. In TNT equivalent (a measure of energy, usually applied to abrupt releases), the recent Siberian event was probably less than 500 kt (kilotons, or thousands of tons of TNT), or 0.5 Mt (megatons, or millions of tons of TNT). The impact believed by many paleontologists to be the likely main cause of dinosaur extinction, is estimated to have released about 100,000,000 Mt of energy. So if you want to understand how big that was (impossible, of course, for the human imagination to really encompass such an event) -- then you have to think of 200 million explosions like that over Chelyabinsk, all occurring in the same split second. The crater from the impact that ended the Cretaceous era is more than 110 miles (!) in diameter. The resulting tsunami is calculated as more than 10,000 feet in height, and would of course have swept all of the world's oceans. The asteroid whose collision with earth triggered this calamity is estimated to have been more than 6 miles in diameter. It's likely that earth was violently heated by all of that energy, and then rendered cold by the vast amount of material propelled into the atmosphere. (Although it's expected from atmospheric models that the dust would circulate worldwide, we don't have to trust them, because geologists have found debris from the impact in every corner of the world.) ______________________________________________ To consider a much more recent case, the 1908 Tunguska event was (by comparison) a tiny one. The estimated energy is perhaps 10 to 30 Mt. But it flattened about 800 square miles of forest -- the trees broke at their bases like matchsticks. Quite possibly, no one died in that event (it's hard to be sure about this) because the territory was so empty at that time. But if it had occurred over a populated area, or worse an urban area, the death toll might have been vast. ragingbull Member send PM   block PM add to buddies Send: 2/16/2013 8:58:02 PM   Have they determined where the ancient meteor landed, Mr. Durak? durak Member send PM   block PM add to buddies Send: 2/16/2013 9:28:57 PM   @rb: Yes, less than 5 miles off the coast of the Yucatan peninsula of Mexico. The crater was discovered only in recent years, because it is (a) very old and therefore mostly weathered down, (b) about evenly split between land and sea, and (c) so gigantic that nobody was looking at the subtle variations in topography and thinking, "oh, this is part of a crater that is 350 miles in circumference." ragingbull Member send PM   block PM add to buddies Send: 2/17/2013 10:56:59 AM   Too bad the dinosaurs didn't have nukes. durak Member send PM   block PM add to buddies Send: 2/17/2013 1:36:22 PM   Can you PROVE dinosaurs didn't have nukes? http://tinyurl.com/ajg6hym durak Member send PM   block PM add to buddies Send: 2/17/2013 8:00:36 PM   Another great comment from Russia (in translation, of course): “It was a fantastic feeling how we were all united by our common [doom], as everybody was sharing with everybody else how scared he was and how he had his pants full" ragingbull Member send PM   block PM add to buddies Send: 2/17/2013 8:21:54 PM   That's a good one, Mr. Durak. That would mean a dinosaur figured out e=mc2 a millions of years before Einstein. http://tinyurl.com/a6vpse9 kiwinorth Member send PM   block PM add to buddies Send: 2/18/2013 3:25:44 AM   In other news, for those of you who are more connected to Ukraine, on Wednesday a roof collapsed at the Chernobyl nuclear station. There was no elevation of radiation readings, and no health consequence is expected. 20 something year old steel structure,, i'm a little surprised it has rusted away, i have heard it is rusting(i presume we are talking of the cover made for the plant that has collapsed?? if you look around ukraine and russia,,, things just dont rust away like other parts of the world,,, they dont even bother to protect a lot of metal work over there because of this.. makes one wonder if its to do with the radiation or the compounds they dumped on the place? i was told the meteor in Siberia 1908, they think was actually ice, for no meteor bits have ever been found. CHELYABINSK its lucky that shit didnt happen during the cold war,,, it possible all you Americans and maybe Briton would have had russian warheads up your good ol @ss. rather frightening when when you think about it, theres been a few wars started from dumb accidents as we know. durak Member send PM   block PM add to buddies Send: 2/18/2013 12:17:33 PM   @kiwi: I've long wondered how much danger exists, of a meteor impact being mistaken for a missile attack. In some ways they can look identical (at first, anyway). I *hope* that the states with nuclear ballistic missiles are smart enough to have realized that the probability of such a false alarm is pretty high, and have provided for this in their attack assessment. On the other hand, I know that a Scandinavian launch of a small scientific rocket triggered the Russian system, and it was left to the discretion of drunken president Yeltsin to decide whether to counterattack. Oi! About Chernobyl -- I haven't yet seen any analysis of the failure, other than the collapse being triggered by the weight of snow. From the photos I have seen, the roof (reportedly constructed since the accident) is concrete, but this doesn't mean that corrosion of metal parts wasn't a factor. Luckily, the collapse was in a turbine building, where (to my understanding) no great quantity of radioactive material would be present.
