On the morning of October 11, the reporter of Beijing Youth Daily contacted Songyuan municipal government and natural resources bureau. The staff said that they had not received the relevant report yet. Zhang Baolin, a senior meteorite expert at the Beijing Planetarium, told the Beiqing daily that the scientific researchers concerned are looking for accurate satellite positioning data, and finally determine whether it is a meteorite Crash Based on the discovery of the real object.
Where did the meteorite fall
At about 0:16 a.m. on the 11th, the news that a meteorite suspected of falling near Songyuan City, Jilin Province was hot on the Internet.
On the morning of November 11, the reporter of Beiqing daily contacted Zhang Baolin, a senior meteorite expert at the Beijing Planetarium. He introduced that citizens not only in Shenyang, Changchun, Songyuan and other places, but also in Tibet, Guangdong and other places saw the fire of the suspected meteorite falling. At present, the news of the suspected meteorite falling has attracted attention among the professional and amateur teams of meteorites, as well as meteorite lovers and meteorite collectors. Many people have rushed to the scene to understand the situation.
Zhang Baolin told the Beiqing daily that from the relevant videos released by netizens, it should be the Fire Meteor phenomenon, that is, the meteor phenomenon produced when larger meteoroids fall. The firelight phenomenon seen by netizens should occur at an altitude of 12 km to 120 km from the ground. In this space, the meteoroid will shine. It enters the atmosphere very fast, and friction will generate heat. It will heat the surrounding air to tens of thousands of degrees, and the surface temperature can reach 4000 degrees. At this time, it will shine. In general, meteorites may burst under the resistance of air when they are close to the ground.
With regard to the determination of the location of the meteorite falling, Zhang Baolin said that at present, there are relatively accurate satellite monitoring methods in the world. In addition, according to the location provided by the witnesses, the angles of the witnesses in three different directions can roughly determine the location of the meteorite falling. " But in the end, we have to determine whether it is a meteorite fall according to the discovery of the real object. At present, the scientific researchers concerned are looking for accurate satellite positioning data. " Zhang Baolin said that according to the existing situation, it is speculated that meteorites should fall. It is speculated that the falling area is most likely at the junction of Heilongjiang and Jilin and around Songyuan. However, at present, the amount of meteorites falling is not large, and only a few kilograms of meteorites may fall on the surface.
On the morning of November 11, the reporter of Beiqing daily contacted the office of Songyuan municipal government. The staff said that they had not received any news about the meteorite landing. Subsequently, the staff of Songyuan Natural Resources Bureau said that they need to carry out work according to the arrangements of relevant departments. At present, they have not received the relevant notice.
