Radiant positions of the particles modeled using an orbit obtained by backward integration of observed meteors. The positions of radiants are shown in the same way as those in Fig. 1a. However, the initial orbit to model the stream was that of video meteor SNTC-118490, which was obtained via numerical integration of the current orbit for time 30 kyr before the present in this case. The P-R drag influencing the motion of modeled particles characterized with β = 0.003 was considered, too.
