Changes to Submitted Observatory Proposals

For semester proposals, proposers have the ability to withdraw their proposal directly through the PST without needing to contact the NRAO Science Helpdesk. If this action is taken prior to the proposal deadline, a new proposal can be submitted. Note that the PST currently permits proposal withdrawal only if it’s initiated a minimum of fifteen (15) minutes before the deadline. Beyond this time frame, proposers will need to contact the NRAO Science Helpdesk to withdrawal a proposal. After the proposal deadline, a submitted proposal may be withdrawn but no longer modified. Requests for withdrawal should be made via the NRAO Science Helpdesk. It is at the discretion of the Observatory to permit withdrawal however; if the review process has begun, the proposal will not be withdrawn.

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
