Observing > Call For Proposals > NRAO Call for Proposals: Semester 2021A


The National Radio Astronomy Observatory (NRAO) invites scientists to participate in the Semester 2021A 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 2021A proposals is Monday, 3 August 2020, at 17:00 EDT (21:00 UTC). 

We would like to highlight that NRAO is offering staff assistance with VLBA observation setup and data reduction for new and novice VLBA users.  For more information see the VLBA, HSA and GMVA Proposal Guide.

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.
