Introduction
The National Radio Astronomy Observatory (NRAO) invites scientists to participate in the Semester 2023A Call for Proposals for the Karl G. Jansky Very Large Array (VLA) and the Very Long Baseline Array (VLBA), High Sensitivity Array (HSA), and Global 3mm VLBI Array (GMVA).
The submission deadline for Semester 2023A proposals is Monday, 1 August 2022, at 17:00 EDT (21:00 UTC).
We would like to highlight that the AGN science category will be split into two in order to manage the increasing number of proposals received in this science area. Please see News & Opportunities for more information.
Proposal preparation and submission are handled via the NRAO Proposal Submission Tool (PST) available at NRAO Interactive Services. Proposers who need assistance with proposal preparation or have questions regarding the Call for Proposals or NRAO telescope capabilities should contact Observatory staff via the NRAO Helpdesk. Note that using these tools (both the PST and the Helpdesk) requires registration.
