Distribution of geocentric radiants of modeled particles, which approach the Earth’s orbit within 0.05 au at the present. These radiants are indicated by full black circles. The streams were modeled for t_ev = 500 P_o and the strength of the P-R drag characterized with value of parameter β = 0 (plot a)); 0.001 b); 0.005 c); and 0.009 d). The particles of the 12P-associated stream approach the Earth’s orbit in a maximum of four filaments. These are labeled F1, F2, F3, and F4 in plot a). The radiants of the observed video meteors from two corresponding showers are also shown, indicated by green crosses. All radiant positions are shown in the Hammer projection of celestial sphere in the equatorial coordinates. The sinusoid-like curve illustrates the ecliptic.
