To the Geoscience Synchrotron User Community: As you may be aware, late last year NSF issued a Dear Colleague Letter to announce plans for a competition for the management and operation of synchrotron-hosted analytical capabilities for Earth Science research. While a call for proposals has not yet been released by NSF, we have taken the step of establishing asteering committee to assist the Geoscience synchrotron user community in responding to the new initiative from NSF. A request for suggestions for committee members was sent to the community in December 2020. Based on the response, a committee has been established which includes representation from existing organizations (COMPRES, GSECARS) as well at-large members from the user community.The committee was selected to include representatives from many of the Geoscience disciplines that access synchrotron facilities.Tom Duffy (Princeton) is serving as Chair of the Steering Committee.Information about the committee and our activities can be found at: https://gsecars.uchicago.edu/synchrotron-geoscience/ <https://gsecars.uchicago.edu/synchrotron-geoscience/> A number of workshops and townhalls have been held, and plans for future activities are on-going.The website will be updated with information on these activities going forward. We welcome input and comments from the community. Tom Duffy on behalf of the Geoscience Synchrotron Users Steering Committee
