Comparison between the observed flux profile of the λ-Sculptorids with the predictions of Vaubaillon et al. (2023). Coloured lines indicate the maximum activity time predicted by the different models presented in Table 2 of Vaubaillon et al. (2023), and marked by the initials of the co-authors. The solid lines illustrate the modeled activity predicted by AE for particles with sizes above (blue) or below (red) one millimetre, with nodal-crossing locations closer than 0.02 AU from the Earth’s orbit at the time of the shower (AE₁ model). The black symbols represent the flux measured by GMN at a limiting magnitude of +6.5.
