All VLBA proposals must be submitted with a VLBI Proposal Cover Sheet, which is available as described in Section 18.3. The cover sheet can be used to request the VLBA and/or VLBA affiliates.

VLBA propoals should be sent to: Director, NRAO, 520 Edgemont Road, Charlottesville, Virginia 22903-2475, USA. All EVN proposals must be submitted with a VLBI Proposal Cover Sheet. EVN propoals should be sent to: R. Schwartz, EVN Scheduler, MPIfR, Auf dem Hügel 69, D-53121 Bonn, GERMANY. Global VLBI observations require proposals to both the VLBA and EVN, using the addresses given above.
Proposals requesting antennas unaffiliated with the VLBA or the EVN must be sent to the directors of those antennas.
