The Green Bank Observatory (GBO) invites scientists to participate in the GBO's Semester 2017A Call for Proposals for the Green Bank Telescope (GBT).  Proposals requesting the GBT as part of High Sensitivity Array (HSA), and Global 3mm VLBI Array (GMVA) should be submitted through the Long Baseline Observatory's call (available here).

The submission deadline for Semester 2017A proposals is Monday, 1 August 2016, at 17:00 EDT (21:00 UTC).

The GBO especially wishes to highlight continuing opportunities for joint observations with the Chandra X-ray Observatory, the Hubble Space Telescope and the Swift Gamma-Ray Burst Mission.

The GBO strongly encourages proposers to read through the "News and Opportunities" page carefully as there have been a number of changes made to instrument availability and student support opportunities for 17A.

Proposal preparation and submission remain via the NRAO Proposal Submission Tool (PST) available at NRAO Interactive Services. Note that PST use requires registration.  Proposers who need assistance with proposal preparation or have questions regarding the Call or GBT capabilities should contact Observatory staff via the Helpdesk.

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.
