Given time is an estimate based on approximate radiant position. H is the height above sea level, $L_{\rm obs}$is the length of observed trajectory. The subscript ``B'' denotes values at the beginning of the atmospheric trajectory, the subscript ``E'' at the end point. N is the number of stations where the fireball was photographed. Values of individual entries are given with an accuracy of one or two last digits.
