Notes. Δt is an uncertainty in the beginning time, Hbeg and Hend are observed beginning and terminal heights, HbegS and HendS are beginning and terminal heights observed by a photographic spectral camera at station Churáňov (CS), L is the observed length of the atmospheric trajectory, ZDR is the zenith distance of the radiant at Hend, Mabs is the absolute (100 km distance) magnitude, vinf is the initial velocity, N is the number of stations where the meteor was observed (number in parentheses is number of stations used for the trajectory solution), and Cam refers to cameras by which the meteor was recorded (abbreviations follow the designation as in Table 1). (a) Beginning of video meteor at 4:51:24 UT was not in the FOV of our regular cameras, the beginning is from the supplementary ZWO camera with lower sensitivity; (b)record from Křišťanov was not used since the meteor was recorded on the very edge of the FOV and the trajectory shows systematic shift of 70 m in comparison to final solution.
