Positions of radiants of theoretical particles representing the quasi-stable part (filaments F1 and F2) of the modeled stream of comet C/1979 Y1, which currently move in orbits, along which they can approach the Earth’s orbit within 0.05 au (plot a). The radiant positions of the meteors of corresponding showers separated from the CAMS (red crosses for F1 and D_lim = 0.07 and blue asterisks for larger D_lim and both F1 and F2) and SonotaCo (green empty squares) video databases are shown in plot b. The shown theoretical radiants of filaments F1 and F2 were obtained in the models for t_ev = 20 kyr and β = 0.00001. The positions are shown in the equatorial coordinate frame. The sinusoid-like curve illustrates the ecliptic.
