Abstract: 

Based on infrasound signal observations made by 17 infrasound stations and published in the literature, the statistical analysis of the basic signal parameters (time delay, celerity, duration, oscillation period, and amplitude) has been performed as a function of the horizontal distance from the luminosity region of the Indonesian super-bolide to the place of a corresponding infrasound station. The approximating relations for the signal parameters as a function of range are presented. Correlation diagrams are constructed and analysed. The principal meteoroid parameters, the corrected infrasound wave celerity, and the mean troposphere-stratosphere wind speed are estimated.

Keywords: fitted dependences, infrasonic signal, main parameters, meteoroid
