Dynamic and Fixed-Date Scheduling

$Most projects on the VLA are observed dynamically, based on a combination of the scheduling priority and the expected properties of the array and the weather. Such dynamic scheduling enhances science data quality and the array's ability to discharge time-sensitive science. Some projects requiring coordinated observations with other telescopes will be scheduled on a fixed sidereal date.$

$Please see the scheduling officers' home page for further information, at http://science.nrao.edu/facilities/evla/sched/schedsoc$

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.
