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.

Presented at the 68th Annual Meeting of the Meteoritical Society, Abstract number 5012.
