Heliographic longitude–latitude projection of the sample of trajectories of nanodust emitted from the orbit of the comet Ikeya–Seki. The trajectories end at 1 AU from the Sun. The points of emission are marked by squares. Separate panels show the results for nanodust with different Q∕m ratios. The cases of positive charge: Q∕m = 10⁻⁴ e/m_p and Q∕m = 10⁻⁵ e/m_p show the behavior of nanodust for the “defocusing” solar magnetic field polarity. The results for nanodust with Q∕m set to negative values: Q∕m = –10⁻⁵ e/m_p and Q∕m = –10⁻⁶ e/m_p represent also the behavior of the positively charged dust for the “focusing” polarity. For the Q∕m = –10⁻⁶ e/m_p case, the drift along the heliospheric current sheet occurs for some trajectories.
