Introduction
The Long Baseline Observatory (LBO) invites scientists to participate in the LBO's Semester 2019A 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 2019A proposals is Wednesday, 1 August 2018, at 17:00 EDT (21:00 UTC).
The LBO strongly encourages proposers to read through the "News and Opportunities" page carefully as there are changes throughout the call for proposals.
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. We especially urge proposers new to proposing for the VLBA/HSA or even those who have less experience in VLBI to use the Helpdesk in a timely fashion in advance of the proposal deadline to understand the technical use of the VLBA/HSA.
Approximately 1000 to 1200 hours of VLBA observing time are expected to be available for Open Skies in observing semester 2019A.
