Comparison of the λ-Sculptorid flux observed by SAAMER (blue boxes) and GMN (black symbols) in 2023. The meteoroid fluxes measurements provided in Vaubaillon et al. (2023); Vida et al. (2024) are compared with the modelled flux, when retaining particles that approached the Earth within Delta;× = 0.02 AU (left panel) or Delta;× = 0.005 AU (right panel). Coloured lines indicate the maximum activity time predicted by the different models of Vaubaillon et al. (2023), marked by the initials of the co-authors. While only small particles from the 1974 were retained in the second scenario, mm-sized particles ejected from the comet prior to 1900 were found to approach the Earth within 0.02 AU (pink area in the left panel). Both dynamical models suggest that if larger particles from older trails provide a good match with the activity reported by GMN, smaller particles from the 1974 trail are necessary to explain the first peak detected by SAAMER.
