The relative distribution of atmospheric encounter speeds at constant mass for observations made as part of the Harvard Radio Meteor Project synodic year observations has been recalculated using a cumulative mass index, α = 1.1 ± 0.1, and the mass velocity relation from F. Verniani (1973, J. Geophys. Res. 78, 8429-8462), γ = 4.23 ± 0.07. A discrepency in the bias-corrected values reported by Z. Sekanina and R. B. Southworth (1975, NASA Contractor Report CR 2316, Smithsonian Institution, Cambridge, MA) is identified as a possible typographical error with the relative numbers of high speed meteors increased by 10 2 times over that of the previous analysis. The reappraised distribution is in good agreement with that reported by J. E. Erickson (1968, J. Geophys. Res. 73, 3721-3762) but is based on data with considerably improved statistical reliability and samples a mass range more directly applicable to spacecraft impact studies. The mean impact speed weighted to equivalent crater diameter using a mass-velocity relation, mv 2, is 23.6 km sec -1. This value moves the S. G. Love and D. E. Brownlee (1993, Science 262, 550-553) mass influx peak to 8 × 10-6 g (175-μm-diameter particles), half the previous mass, and brings their cumulative flux curve into much closer agreement with Grün et al. (1985, Icarus 62, 244-272).
