Abstract

IDP flag U2108 flew for 8.05 hours November 19–23, 2002 shortly after the Leonid meteor shower associated with comet Tempel-Tuttle. Flags L2054, L2055, and U2121 flew together for 7.90 hours on April 30–31, 2003 coinciding with Earth’s passage through the dust of comet Grigg-Skjellerup. We analyzed He, Ne, and Ar isotopic compositions in a suite of 16 of these particles. Distinguishing characteristics of their origin were sought by comparing with previous IDP analyses.
