Simulation results and observation image of the dust tail on October 23, 2013. Panels a-f show simulated dust tails with an ecliptic longitude of a rotation axis of 70^°, and local latitudes of 40^°, 50^°, 60^°, 70^°, 80^°, and 90^°, respectively. Panels g-k show simulated dust tails with an ecliptic longitude of a rotation axis of 250^°, and local latitudes of −40^°,−50^°,−60^°,−70^°, and −80^°, respectively. Panel 1 is an observational image from the Hubble telescope (program number 13475; Jewitt et al. 2015b). The direction of the antisolar vector (-S), the direction of the anti-velocity vector (-V), the northern direction (N), the eastern direction (E), and the scale bar are marked in panel 1.
