Computation characteristics
We'd like to present the results of Finlayid meteor stream simulation aimed to the prediction of shower activity in the years 1901-2100. Simulation was made for the trails of latest 28 revolutions, i.e, from the 1807 trail, as well as evolution of the next 17 trails to be ejected in the future, up to 2093 trail. The Author used the program by S. Shanov and S. Dubrovsky "Comet's Dust 2.0" to calculate orbital elements of ejected meteor particles. To estimate expected ZHRs for different encounters the model described in [3] was used with some Author's alterations made in order to adopt the model for ejection velocity (Vej) instead of da0 (difference in a-semimajor axis) and to turn the model from the Leonid stream (for which it was originally created) to the Finlayids. The computation considered only gravitational forces. The following parts of trails were computed: the first 15 rev. trails for ejection velocities [-50;100] m/s, 16-30 rev. trails - [-30;50] m/s, 31-50 rev. trails - [-20;30] m/s.
Finlayid predictions are given as short conclusions for the years for which possible activity enhancements are found.

Orbit of the comet 15P in 1901-2100
The Author used initial orbital elements of 15P, starting from the perihelion of 1807 and up to 2100 one, presented by Kazuo Kinoshita [2]. Orbital elements of 15P in the period 1901-2100, as well as values of minimal distances to the Earth orbit for these elements and relative solar longitudes are given in Table A2.

Orbital elements are given for the Epoch J2000. The following of them are denoted with symbols: q - perihelion distance; e - eccentricity; AOP - argument of perihelion; LAN - longitude of ascending node; i - inclination. MD - minimal distance to the Earth's orbit, SL - solar longitude of MD-point. Positive value of minimal distance means that point of such minimum lies outside the Earth orbit, and negative value means that this point is inside the Earth orbit.
