Introduction
The National Radio Astronomy Observatory (NRAO) invites scientists to participate in the Semester 2024B 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 mm VLBI Array (GMVA).
The submission deadline for Semester 2024B proposals is Wednesday, 31 January 2024, at 17:00 EST (22:00 UTC).
For the VLA, the A-configuration will be available. It is anticipated there will be around 1715 hours on the VLA and 800 hours on the VLBA available for science observing. Opportunities for Joint proposals will be available for ALMA, JWST (see What’s New in 24B?), HST, Swift, Chandra, XMM-Newton, and NICER. Joint Proposals with ALMA or JWST need to be submitted to the facility requesting the larger amount of observing time.
The array configurations available for joint ALMA/VLA will be: ALMA C-1 to C-10 and VLA A, D, and C configurations.
The NRAO 2024B Call for Proposals is for observations with the VLA and VLBA/HSA/GMVA; the corresponding call for the GBT can be found at the GBO Call for Proposals.
