2020 Geminids Timed CollectionParticles from the 2020 Timed Collection of the Geminid meteor shower are announced as available for request. Six particles identified as Cosmic are included in the catalog for this collection. The parent body for the Geminid shower is "rock comet" 3200 Phaethon, the target for the upcoming JAXA Destiny+ flyby mission. Particles from this collection may originate from 3200 Phaethon or may be constituents of the sporadic IDP background - Cosmic Dust cannot differentiate between these possibilities using standard preliminary examination analyses. Consortium studies are encouraged for these particles. This catalog is presented as an initial release with possible announcement of additional particles in a subsequent Newsletter. There is an additional set of collectors from this timed collection that have not been fully processed and may contain additional particles. When the collection occurred, we shipped two sets of collectors for use, one intended for collection and a second contingency set. It was recently discovered that the collectors were changed out between the two collection flights, and the contingency collectors could also contain particles. These particles will be processed, and the catalog updated as soon as possible, so stay tuned to future issues of this newsletter for more material from this timed collection.
