Updated modeled activity (postdiction) of the λ-Sculptorid shower from the AE₁ simulation data set, for sub-mm (green) and mm-sized (cyan) particles. In Vaubaillon et al. (2023), only particles crossing the ecliptic plane closer than Δr = 0.02 AU and within ΔT ± 7 days from the Earth were retained in AE₁’s simulation. By increasing the time selection criterion to 20 days, more mm-sized particles ejected from 46P prior to 1908 approached the Earth in 2023. The resulting activity profile (dark blue) is a better match to the observations when including the contribution of older trails.
