Weight Of Chelyabinsk Meteorite Will Be Measured Again
(Source: http://darkgoldforum.net/viewtopic.php?f=137&p=14788)

Special equipment for measuring of the accurate weight of the largest fragment of the Chelyabinsk meteorite will be brought in the Chelyabinsk Regional History Museum on January 26 at 13:00. According to recent data, the weight of “the stranger” is 470 kg - this result was showed by gravimetric measurements of the stone held in November of last year by the scientists from the Institute of Geophysics of the Ural Branch of the Russian Academy of Sciences.

      However, the figures of the meteorite scanning might be not at all accurate, since such devices are very sensitive: they react even to the building vibration and seismic vibrations being echoes of distant earthquakes. According to one of the scientists, Arkadiy Ovcharenko, the accuracy of measurement was negatively affected by the movement of visitors around the museum showcase. A permanent interest to the exhibit made it necessary to finally decide the question of the exact weight of the space visitor. Museum staff managed to find a spring balance capable of measuring very heavy loads weighing over a ton. Scientific officers of the institution hope that the scales would not break down, unlike those used to weight the meteorite on the day it was lifted from the bottom of the lake.
