NRAO/GBO Users Committee

The Users Committee (UC) is made up of users and potential users of NRAO and GBO facilities from throughout the scientific community. It advises the NRAO and GBO Directors and the Observatory staff on all aspects of Observatory activities that affect the users of the telescopes. This committee, which is appointed by the NRAO and GBO Directors, meets annually.
