Notes. ID: cluster identification number, # frag.: number of fragments, Δt: duration, Δυɡ: maximum difference in geocentric velocity, θ: maximum difference in radiant location, Shower: meteor shower linked to the cluster, Orbit: orbit type, Ntot: total number of expected clusters at the time of the detection. Strike-through clusters were ruled out as high-confidence cluster candidates as Δυɡ is significantly high.
