Kozak P. Photometry and kinematics of meteors from TV observations

The methods for kinematical and photometric processing of the double-station meteor TV observational results presented in digital form are developed. The methods include: carrying out of the analysis and investigation of efficiency for the application of different astrometry reduction models, minimization of astrometry calculation errors; development of the original method for determination of trajectory parameters of a meteor in Earth's atmosphere and its heliocentric orbital elements; computation of the errors of all investigated parameters for each individual meteor with the help of statistical and numerical methods; development of the original calibrated photometrical system and calculation of the meteor magnitude along its visible trajectory by means of the experiment "artificial meteor", realization of all necessary corrections; development of the appropriate software. The carried out methods was applied to process the meteor observational results of Leonid shower in 2002. Trajectory parameters of 28 meteors and their orbital elements were obtained. Three meteors with begin heights of 140-150 km ware registered. 11 meteors, which were observed during one hour at peak of meteor shower activity and which compose a compact group with mean radiant coordinates: RA=154°.25±0°.45, Dec=21°.90±0°.52 have been selected.
