The method is designed for use with video material (regardless of the motion speed of the video recorder) for daytime bolide events. Kinematic parameters are obtained for the superbolide event followed by the Chelyabinsk meteorite shower on February 15, 2013. The (geodetic) azimuth of the meteoroid\u2019s trajectory in the Earth\u2019s atmosphere is 283.39\u00b0 \u00b1 1.7\u00b0 (or 101.09\u00b0 \u00b1 1.7\u00b0 toward the radiant). The radiant altitude over the site with observations of the end of the first fragmentation phase is 20.5\u00b0. The geodetic coordinates of the beginning of the bolide phenomenon and the point of suspension of the radiating material at the end of the first fragmentation phase are (64\u00b000\u203202.74\u2033 \u00b1 2.1\u2032 east longitude; 54\u00b030\u203254.66\u2033 \u00b1 3.0\u2032 north latitude) and (61\u00b011\u203201.88\u2033 \u00b1 1.6\u2032 east longitude; 54\u00b052\u203206.68\u2033 \u00b1 3.1\u2032 north latitude), respectively. The atmospheric entry velocity is 19.29 \u00b1 0.89 km s\u22121. The height of the start of the light emission is 102.4 km; those of the main fragmentation phases are 28.0 and 24.4 km. The calculated elements for the heliocentric orbit of the Chelyabinsk meteoroid are: Q = 2.66 \u00b1 1.20 AU, q = 0.73 \u00b1 0.01 AU, a = 1.67 \u00b1 0.10 AU, e = 0.57 \u00b1 0.03, i = 7.07\u00b0 \u00b1 0.54\u00b0, \u03a9 = 326.42\u00b0, and \u03c9 = 106.28\u00b0 \u00b1 2.54\u00b0. These parameters are compared with the results obtained by other authors.<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Golubaev, A. V.
