The National Radio Astronomy Observatory (NRAO) invites scientists to participate in the Semester 2020B 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 2020B proposals is Monday, 3 February 2020, at 17:00 EST (22:00 UTC). 

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.
