“In the morning of June 21, 2018 (1:16 Universal Time (UTC)) the space body entered the Earth atmosphere in the Lipetsk region, Russia. This event was detected by a number of registration systems in cars, satellite observations of bolide light curve and subsequent dust trail. The videos, photos, satellite data allow us to calculate the trajectory and the orbit of the Ozerki bolide. The atmospheric entry velocity is 14. 9\u202f\u00b1\u202f1\u202fkm\/s. The height of the depression point is 32.8\u202f\u00b1\u202f0.9\u202fkm and that of the maximum brightness is 27.2\u202f\u00b1\u202f0.9\u202fkm. The pre-atmospheric orbit of the Ozerki meteoroid was also calculated: q\u202f=\u202f0.67\u202f\u00b1\u202f0.04 AU, a\u202f=\u202f0.84\u202f\u00b1\u202f0.02 AU, e\u202f=\u202f0.199\u202f\u00b1\u202f0.030, i\u202f=\u202f18.44\u00b0 \u00b13.05\u00b0, \u03a9\u202f=\u202f89.6561\u00b0 and \u03c9\u202f=\u202f335.29\u00b0 \u00b15.15\u00b0. The geocentric radiant position is RA\u202f=\u202f307.515\u00b0\u00b13 and DEC\u202f=\u202f43.107\u00b0\u00b13. The found material was called Ozerki meteorite and is classified as an ordinary chondrite (L6). The estimated: mass of the meteoroid is 94\u202f\u00b1\u202f20 tons, the energy is 2.5\u202f\u00b1\u202f0.54\u202fkt TNT, diameter is 3.65\u202f\u00b1\u202f0.45\u202fm.”<\/p>\n","protected":false},"excerpt":{"rendered":"
