Comparison of observed and modeled light curves (upper panel) and deceleration (lower panel) of the 4:58:28 UT meteor. Observed data are given as crosses, and the model is shown with smooth solid lines. Deceleration is expressed as the difference of the length along the trajectory (of the brightest part of meteor streak) at the given time from the length expected for constant meteor velocity of 63.35 km s⁻¹. CIRA72 model atmosphere was used to compute the drag.
