METEORITE CHELYABINSK: continuation of the story Sergei V. Kolisnichenko, Verkhnyaya Sanarka, Chelyabinsk oblast. [email protected] n February 15th, 2013 a massive 6 x 8 meter hole was discovered in the thick ice of Lake Chebarkul. Scattered around the lake were tiny stone Оfragments that contained the mineralogical characteristics of chondrite. Evidenced by the size of the hole in the ice, it was inferred that an object weighing half a ton, and with a diameter slightly less than one meter, impacted the surface at termi- nal velocity. Subsequent examinations of the bottom of the lake by geophysical meth- ods gave various results, but it was generally agreed that a large extraterrestrial body was lodged in the lakebed. In those early days of discovery in February the idea of lifting the meteorite out from the bottom of the lake seemed quite feasible; after all, it was only under about 12 meters of water and 7 meters of silt! Chelyabinsk's regional administration assumed the cost of this historic mission, assess- ing the work at three million rubles. The company Aleut from Ekaterinburg quoted the 1.

Small Near-Earth Asteroids As a Source of Meteorites
Small Near-Earth Asteroids as a Source of Meteorites Jiří Borovička and Pavel Spurný Astronomical Institute of the Czech Academy of Sciences Peter Brown University of Western Ontario __________________________________________________________________________ Small asteroids intersecting Earth’s orbit can deliver extraterrestrial rocks to the Earth, called meteorites. This process is accompanied by a luminous phenomena in the atmosphere, called bolides or fireballs. Observations of bolides provide pre-atmospheric orbits of meteorites, physical and chemical properties of small asteroids, and the flux (i.e. frequency of impacts) of bodies at the Earth in the centimeter to decameter size range. In this chapter we explain the processes occurring during the penetration of cosmic bodies through the atmosphere and review the methods of bolide observations. We compile available data on the fireballs associated with 22 instrumentally observed meteorite falls. Among them are the heterogeneous falls Almahata Sitta (2008 TC3) and Benešov, which revolutionized our view on the structure and composition of small asteroids, the Příbram-Neuschwanstein orbital pair, carbonaceous chondrite meteorites with orbits on the asteroid-comet boundary, and the Chelyabinsk fall, which produced a damaging blast wave. While most meteoroids disrupt into fragments during atmospheric flight, the Carancas meteoroid remained nearly intact and caused a crater-forming explosion on the ground. 1. INTRODUCTION Well before the first asteroid was discovered, people unknowingly had asteroid samples in their hands. Could stones fall from the sky? For many centuries, the official answer was: NO. Only at the end of the 18th century and the beginning of the 19th century did the evidence that rocks did fall from the sky become so overwhelming that this fact was accepted by the scientific community.

GEO Quarterly No 38 the Group for Earth Observation June 2013
Group for Earth Observation The Independent Amateur Quarterly Publication for 38 Earth Observation and Weather Satellite Enthusiasts June 2013 Inside this issue . This issue of GEO Quarterly is aimed firmly at newcomers to the hobby—particularly readers who may be setting up their receiving system for EUMETCast for the first time. Mike Stevens has updated and expanded the guide to installing EUMETCast that he originally prepared some nine years ago, and in addition has penned an introduction to MSG DataManager, the software you require to convert the received files into satellite images. Last February’s spectacular meteor event over Russia emphasises the importance of observing away from Earth as well as directly down upon it. Les Hamilton has delved deeply into contemporary Russian news reports to piece together a fascinating illustrated account of the event. For readers migrating to the new Windows 8 operating system, David Taylor provides some helpful notes. There are also articles on phytoplankton blooms, Antarctic icebergs, the Northwest Passage, and ice on Lake Erie.

R.E. Alekseev, Nizhny Novgorod, 603950, Russia 3Institute of Applied Physics, Nizhny Novgorod, 603950, Russia Correspondence to: Andrey Kurkin ([email protected]) Abstract. The results of the numerical simulation of possible hydrodynamic perturbations in Lake Chebarkul (Russia) as a consequence of the meteorite fall of 2013 (Feb. 15) are presented. The numerical modeling is based on the Navier-Stokes 10 equations for a two-phase fluid. The results of the simulation of a meteorite entering the water at an angle of 20 degrees are given. Numerical experiments are carried out both when the lake is covered with ice and when it isn’t. The estimation of size of the destructed ice cover is made. It is shown that the size of the observed ice-hole at the place of the meteorite fall is in good agreement with the theoretical predictions, as well as with other estimates. The heights of tsunami waves generated by a small meteorite entering the lake are small enough (a few centimeters) according to the estimations. However, the danger 15 of a tsunami of meteorite or asteroid origin should not be underestimated. 1 Introduction February 15, 2013 at 9:20 a.m. local time, in the vicinity of the city of Chelyabinsk, Russia (Fig. 1) a meteorite exploded and collapsed in the earth's atmosphere as a result of inhibition.

A Timeline of Meteoric Descent
A Timeline of Meteoric Descent What excited Marshall astronomer Bill Cooke most about publication of the papers related to the Chelyabinsk fireball is how they "present a complete picture of the [event]," he said. He shared the following breakdown of the meteoroid's brief, startling voyage: 1. The approximately 62-foot-wide asteroid, weighing roughly 12,000 tons, enters the atmosphere over Russia, moving slightly north of due east at 42,600 mph. It is first detected on video at an altitude of 59 miles. In Chelyabinsk, on the slopes of the southern Ural Mountains, it is 9:20:21 a.m. 2. Approximately 9.5 seconds later, the fireball begins to break apart. Its speed is still nearly 42,600 mph, but it has quickly dropped in altitude; it is now 28 miles up. 3. The burning meteor continues to drop, and severe fragmentation occurs. As its altitude dips from 25 miles to 16 miles, approximately 500 kilotons of energy -- or about 40 times the explosive energy of the atomic bomb dropped on Hiroshima in 1945 -- are dumped into the atmosphere in just 2.7 seconds. 4. The peak of this event happens at about 19 miles in altitude, where more than 100 kilotons of energy erupt as the meteor travels just one mile. Also at this height, the meteor breaks into 20 boulder-sized fragments, each weighing more than 10 tons and each still moving at approximately 40,000 mph (On the ground directly below the fireball, it shines more than 30 times as bright as Earth's sun, and a cylindrical blast wave is generated, which shortly will affect the Chelyabinsk area -- breaking windows, damaging buildings and causing approximately 1,600 injuries).

The light pollution makes it easy to set up telescopes in the middle of subzero Michigan nights, but that's the best I can say for it. I love my neighborhood, but it's the worst place to observe I've ever had to deal with. Sometimes, though, you just have to deal with it. Our target was the new Type Ia supernova in M82, 2014J. Galaxy observing here is a bad joke, but I can find M81 and M82 in my sleep, and with a 25mm 2" wide-angle eyepiece, they're just barely bright enough to be detectable despite my eyes tearing up and freezing over.

Sapunov1 1Ural Federal University, 19 Mira Street, Ekaterinburg 620002, Russia 2Institute of Geophysics Ural Branch of RAS, Ekaterinburg, Russia a)Corresponding author: [email protected] b)[email protected] Abstract. Increased sensitivity and resolution of geophysical instruments significantly enhances the effectiveness of non- destructive investigation methods for standard geological problems and allows new experiments. We suggest to use modern highly sensitive scalar magnetometers for identification and study of geological and artificial low-contrast objects in a magnetic field. We present application results of a modern nuclear precession magnetometer POS based on the processor Overhauser sensor. The device is developed and produced by the Quantum Magnetometry Laboratory, Ural Federal University, Yekaterinburg, Russia. Experiments conducted in the laboratory and observatories allowed to determine the device absolute accuracy of 0.5 nT and sensitivity of 0.02 nT, and to confirm its operability in large magnetic field gradients. This sensitivity is sufficient for detection of magnetic field changes caused, for example, by tectonomagnetic, seismomagnetic, piezomagnetic effects and electrokinetic phenomena in the geological environment. We conducted field experiments comparing POS magnetometers metrological characteristics with similar instruments from Scintrex and Geometrics. The results confirm measurement high stability in long-term observations of the magnetic field change due to geodynamic processes. We tested POS instruments in various geophysical applications, including prospecting and exploration of minerals (placer and ore gold, hydrocarbons, kimberlites); identification of ferromagnetic objects in cover environments; archaeological sites mapping.
