Filler Programs

There are opportunities for so-called “filler” programs on all telescopes. Observing programs that exploit frequencies below 10 GHz, do not have scheduling constraints, and could benefit from short scheduling blocks are eligible to be considered for “filler” time. The proposal should make clear in the abstract and in the science justification that “filler” time is being requested. If “filler” time is requested, the proposal will be ineligible for scheduling priority A or B. A proposal requesting filler time should not require fixed time or guaranteed monitoring periods.

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.
