Introduction

The Long Baseline Observatory (LBO) invites scientists to participate in the LBO's Semester 2017B Call for Proposals for the Very Long Baseline Array (VLBA), the High Sensitivity Array (HSA), and the Global 3mm VLBI Array (GMVA).

The submission deadline for Semester 2017B proposals is Wednesday, 1 February 2017, at 17:00 EST (22:00 UTC).

The LBO strongly encourages proposers to read through the "News and Opportunities" page carefully as there are changes throughout the call for proposal.

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 VLBA capabilities should submit help requests via the NRAO Helpdesk.

Approximately 1400 to 1600 hours of VLBA observing time are expected to be available for Open Skies in observing semester 2017B.

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.
